IBM DevOps for the Mainframe

March 27, 2015

DevOps is not just for distributed platforms. IBM has a DevOps strategy for large enterprises (usually mainframe shops) too. Nationwide, a longtime mainframe shop, is an early adopter of DevOps and already is reporting significant gains: reduction in critical software defects by 80% and a 20% efficiency gain in its maintenance and support operations in just 18 months.

DevOps, an agile methodology, establishes a continuous feedback loop between software development and deployment/operations that speeds development and deployment while ensuring quality. This is a far cry from the waterfall development methodologies of the mainframe past.

The IBM DevOps initiative, announced last November (link above), taps into the collaborative capabilities of IBM’s Cloud portfolio to speed the delivery of software that drives new models of engagement and business. Software has become the rock star of IT with software-driven innovation becoming a primary strategy for creating and delivering new value to customers. A survey of 400 business and IT executives by the IBM Institute for Business Value showed businesses that are more effective at software delivery are also more profitable than their peers nearly 70% of the time. As such, IBM notes, DevOps provides a way for businesses to remain competitive, applying lean and agile principles to software development to speed the delivery of software that meets new market requirements.

Some mainframe shops, however, continue to operate from a software standpoint as if client/server computing and PCs were still the new game in town. Meanwhile the business units keep complaining about how long it takes to make software changes while long backlogs drag on the IT budget.

DevOps is about continuous software development and deployment. That means continuous business planning, continuous collaborative dev, continuous testing, continuous release and deployment, continuous monitoring, and continuous feedback and optimization in a never ending cycle. Basically, continuous everything.  And it really works, as Nationwide can attest.

But DevOps makes traditional mainframe shops nervous. Mainframe applications are rock solid and crashes and failures almost unheard of. How can they switch to DevOps without risking everything the mainframe stands for, zero failure?

The answer: mainframe DevOps that leads straight into continuous testing, not deployment. The testing can and should be as rigorous and extensive as is necessary to reassure that everything works as it should and anything that will fail has failed. Only then does it go into production.

It would be comforting to the data centers to say that DevOps only addresses systems of engagement; those pesky mobile, collaborative, and social systems that suddenly are making demands on the core mainframe production applications. But that is not correct. DevOps is about integrating systems of engagement with systems of record, the enterprise’s mainframe crown jewels. The trick is to bring together the culture, processes, and tools across the entire software delivery lifecycle, as IBM says, to span it all—mobile to mainframe, slowing down only to conduct as exhaustive testing as the enterprise requires.

Mainframe tools from the era of waterfall methodologies won’t cut it. Rational offers a set of tools starting with Blue Agility. IBM also offers an expanded set of tools acquired through acquisitions such as UrbanCode (release automation) and GreenHat (software quality and testing solutions for the cloud and more) that offer an integrated developer experience on open cloud platforms such as Bluemix to expedite DevOps collaboration, according to IBM.

Expect push back from any attempt to introduce DevOps into a traditional mainframe development culture. Some shops have been developing systems the same way for 30 years or more. Resistance to change is normal. Plan to start gradually, implementing DevOps incrementally.

Some shops, however, may surprise you. Here the mainframe team senses they are falling behind. IBM, of course, has tools to help (see above). Some experts recommend focusing on automated testing early on; when testing is automated DevOps adoption gets easier, they say, and old school developers feel more reassured.

At IBM Edge2015, there are at least 2 sessions on DevOps: Light Up Performance of Your LAMP Apps and DevOps with a Power Optimized Stack; and CICS Cloud DevOps = Agility2. BTW, it is a good time to register for IBM Edge2015 right away, when you can still get a discount.

Vodafone Spain Picks IBM zSystem for Smarter Cities Initiative

March 19, 2015

The Vodafone initiative, as reported here previously, leverages the most advanced mobile communications technology including citywide sensors and a Global M2M Platform that will enable the connection of thousands of sensors to the intelligent Vodafone Connected City system. The new cloud-based system will run on IBM Linux z Systems. The Linux z Systems were selected for their high security, which protects cloud services while also delivering the speed, availability, and efficiency required to drive mobile services at scale.  To do something at scale you really do want the z System.

For Vodafone this represents the beginning of what they refer to as a Smarter Cities services initiative. The effort targets local governments and city councils with populations ranging between 20.000 – 200.000 citizens. The services provided will address customer’s needs in the following key areas: urban vitality, public lighting, energy efficiency, waste management, and citizen communications.

In effect, Vodafone is becoming a SaaS provider by leveraging their new zSystem. Vodafone’s customers for this are the government groups that opt to participate. The company announced the effort at the World Mobile Congress in Barcelona at the beginning of the month.

One of the initial participants will be Seville, the capital of the province of Andalucía, where a control and development center will be established by Vodafone. The telco will invest more than 243 million euros over two years on telecommunications infrastructure, encouraging the development of the technology sector and developing projects to create strategic growth in the region.

Initially, the center will focus on creating smart city solutions that can easily and efficiently be used by cities ranging from 20,000 to 150,000 residents; cities that otherwise may not have the funds to invest in smart city infrastructure projects on their own. This center is also expected to help make the Andalucía territory of Spain a leader in the development of Big Data and smart solutions.

IBM is delivering the full stack to Vodafone: a set of cloud services that include an enterprise zSystem Linux server (IBM zBC12), v7000 storage, IBM intelligent operations, an information services solution, and more.  Vodafone opted for the z and Linux to enable cost-efficient, highly secure cloud services while also delivering the speed, availability and efficiency required to drive mobile services at scale. IBM Intelligent Operations software will provide monitoring and management of city services. IBM’s MobileFirst platform will be used to create citizen-facing mobile applications while IBM Information Server and Maximo asset management software will round out the IBM stack.

Overall, IBM, the zSystem, and Linux brought a number of benefits to this initiative. Specifically, the zSystem proved the least expensive when running more than seven vertical services as Vodafone is planning. An example of such a vertical service is the public lighting of a city. This also is where scalability brings a big advantage. Here again, the zSystem running Linux delivers scalability along with greater security and regulatory compliance. Finally, another critical capability for Vodafone was the zSystem’s ability to isolate workloads.

In short, the zSystem’s security and regulation compliance; reliability, resilience, and robustness; strong encoding and workload isolation, workload management and ability to meet SLAs; scalability; and high efficiency clinched the Vodafone deal.

This could prove a big win for IBM and the zSystem. Vodafone has mobile operations in 26 countries, partners with mobile networks in 54 more, and runs fixed broadband operations in 17 markets. As of the end of 2014, Vodafone had 444 million mobile customers and 11.8 million fixed broadband customers. Vodafone Spain’s 14.811.000 mobile customers and 2.776.000 broadband ones will certainly take maximum advantage of the zSystem’s scalability and reliability.

…as a follow up to last week’s report on recent success coming from the OpenPower Foundation that string continued this week at the OpenPOWER Inaugural Summit with the OpenPOWER Foundation announcing more than ten hardware solutions spanning systems, boards, cards, and a new microprocessor customized for the Chinese market.  Built collaboratively by OpenPOWER members, the new solutions exploit the POWER architecture to provide more choice, customization and performance to customers, including hyperscale data centers.

Among the products and prototypes OpenPOWER members revealed are:

  • Firestone, a prototype of a new high-performance server targeting exascale computing and projected to be 5-10x faster than today’s supercomputers. It incorporate technology from NVIDIA and Mellanox.
  • The first GPU-accelerated OpenPOWER developer platform, the Cirrascale RM4950, resulting from collaboration between NVIDIA, Tyan, and Cirrascale.
  • An open server specification and motherboard mock-up combining OpenPOWER, Open Compute and OpenStack by Rackspace and designed to run OpenStack services.

Other member-developed new products leverage the Coherent Accelerator Processor Interface (CAPI), a hallmark feature built into the POWER architecture. DancingDinosaur initially covered CAPI here.

Reminder: it is time to register for IBM Edge2015 in Las Vegas May 10-15. Edge2015 combines all of IBM’s infrastructure products with both a technical track and an executive track.  You can be sure DancingDinosaur will be there. Watch for upcoming posts here that will highlight some of the more interesting sessions.

Recent IBM Successes Target Mobile

March 6, 2015

IBM introduced its latest set of MobileFirst for iOS apps at Mobile World Conference, held this week in Barcelona. Not coincidentally, Vodafone Spain, along with IBM, announced its Connected City Initiative to help Spanish cities drive new efficiency. BTW, IBM launched its first set of iOS business apps this past December.

The Vodafone initiative, according to the company, leverages the most advanced mobile communications technology including citywide sensors and a Global M2M Platform that will enable the connection of thousands of sensors with the intelligent Vodafone Connected City system. The new cloud-based system will run on IBM Linux z Systems. The Linux z Systems were selected for their high security, which enables cloud services while also delivering the speed, availability, and efficiency required to drive mobile services at scale.  To do something at scale you want the z System.

But more interesting to DancingDinosaur readers may be the latest set of MobileFirst for iOS apps that target banking and financial services, airlines, and retail. These are strong areas of interest at IBM z Systems shops. At the announcement, more than 50 foundational clients including Air Canada, American Eagle Outfitters, Banorte, Boots UK, Citi, and Sprint have signed on for apps that deliver the complete expertise and capabilities of those companies to their employees wherever they interact with clients and do it faster, more easily, and more securely than ever before via the Apple iPhone and iPad.

These apps promise to transform the job roles and effectiveness of hundreds of millions of professionals globally. For example, Boots UK staff will gain access to real-time data and insight from across the company through their iOS device, allowing them to offer shoppers even greater levels of service, such as real-time stock availability and easy in store ordering. The result: new levels of convenience and accessibility for Boots customers.

Specifically, the latest IBM MobileFirst for iOS applications address:

  • Passenger Care (Travel)empowers customer service agents to address traveler needs from anywhere by enabling a smoother, more personalized experience while speeding check-in and easing airport congestion.
  • Dynamic Buy(Retail)—retailers gain real-time perspective and data-driven recommendations on how products are performing and data-driven recommendations that help retailers realize better return on investments.
  • Advisor Alerts(Banking and Financial Services)—uses analytics to help financial professionals prioritize client-related tasks on-the-go while backed by customized analytics that tells the advisor what’s most important through a personalized dashboard that displays recommended next steps.

The new apps are designed to fundamentally redefine the ways enterprises empower their professionals to interact, learn, connect, and perform. Built exclusively for iPhone and iPad, IBM MobileFirst for iOS apps are delivered in a secure environment, embedded with analytics, and linked to core enterprise processes. The apps can be customized for any organization and easily deployed, managed and upgraded via cloud services from IBM specifically for iOS devices.

Making this happen behind the scenes at many organizations will be IBM z System-based data and logic, including not only CICS but also Hadoop and other analytics running on the z, increasingly in real time. Of course, it all revolves around IBM’s MobileFirst, which allows enterprises to streamline and accelerate mobile adoption. In addition to the IBM-Apple iOS applications organizations can develop their own mobile apps using streamlined tool sets like IBM Bluemix.

BMC and Compuware to Drive Down Mainframe Costs

February 20, 2015

This year jumped off to an active start for the mainframe community. The introduction of the z13 in January got things going. Now Compuware and BMC are partnering to integrate offerings of some their mainframe tools to deliver cost-aware workload and performance management. The combined tools promise to reduce mainframe OPEX even as z systems shops try to leverage their high-value mainframe applications, data, and processing capacity to meet rapidly evolving business challenges.

 compuware bmc logos hi res

Not that things had been quiet before, especially if you consider IBM scrambling to reverse successive quarters on poor financial performance with a slew of initiatives. During that time Compuware went private last fall; about a year earlier BMC went private. Now you have two companies collaborating to deliver tools that will help mainframe shops reduce their software costs. DancingDinosaur has covered previous cost-saving and efficiency initiatives from each of these companies here and here.

Driving this collaboration is the incessant growth of new mainframe workloads, which will likely accelerate with the new z13. Such workload growth is continually driving up the Monthly License Charge (MLC) for IBM mainframe software, which for sub-capacity environments are generally impacted by the highest rolling four-hour average (R4HA) of mainframe utilization for all applications on each LPAR, as measured in MSUs. IBM is helping with discounts for mobile workloads and its new ICAP and country multi-plex pricing, which DancingDinosaur covered here, but more is needed.

The trick requires continually managing those workloads. In effect, IT can most effectively reduce its sizable IBM z Systems software costs by both 1) tuning each application to minimize its individual consumption of mainframe resources and 2) orchestrating application workloads to minimize the LPAR utilization peaks they generate collectively at any given time.  Good idea but not easy to implement in practice. You need automated tools.

According to Frank DeSalvo, former research director at Gartner: “The partnership between BMC and Compuware launches an integrated opportunity for mainframe customers to manage workload inefficiencies in a manner that has not been achievable to-date.”   This partnership, however, “helps organizations leverage their IT budgets by enabling them to continuously optimize their mainframe workloads, resulting in cost effective decisions for both current and future spending.,” as DeSalvo was quoted in the initial announcement.

Specifically, the Compuware-BMC collaboration brings together three products: BMC Cost Analyzer, BMC MainView, and Compuware Strobe.

  • BMC Cost Analyzer for zEnterprise brings a financially intelligent workload management tool that enables z data centers to identify MLC cost drivers and take appropriate measures to reduce those costs.
  • BMC MainView provides real-time identification of application performance issues, enabling customers to quickly eliminate wasteful MSU consumption.
  • Compuware Strobe delivers deep, granular and highly actionable insight into the behavior of application code in the z systems environment.

The partners integrated the products so they actually work together. One integration, for instance, allows BMC Cost Analyzer to call Compuware Strobe for a detailed analysis of the specific application component for peak MLC periods, enabling customers to proactively tune applications that have the greatest impact on their monthly software licensing costs. A second integration with BMC MainView allows customers to either automatically or manually invoke Strobe performance analysis—empowering mainframe staffs to more quickly, efficiently, and consistently when performing cost-saving tuning tasks.

BTW, at the same time Compuware introduced the latest version of Strobe, v 5.2. It promises deep insight into how application code—including DB2, COBOL 5.1, IMS and MQ processes—consume resources in z environments. By providing these insights while making it easy for multi-discipline mainframe ops teams to collaborate around these insights Strobe 5.2 enables IT to further drive down mainframe costs. At the same time it improves application responsiveness.

Besides the software licensing savings that can result the organization also benefits from performance gains for these applications. These too can be valuable since they positively impact end-user productivity and, more importantly, customer experience.

DancingDinosaur feels that any technology you can use to automate and streamline your systems operations will benefit you because people are always more expensive and less efficient than technology.

New Software Pricing for IBM z13

February 6, 2015

Every new mainframe causes IBM to rethink its pricing. This makes sense because mainframe software licensing is complex. The z13 enables different workloads and combinations of uses that merit reexamining the software licensing. But overall, IBM is continuing its strategy to enhance software price/performance with each generation of hardware. This has been the case for as long as DancingDinosaur has been covering the mainframe. (click graphic below to enlarge)

 IBM z13 technology update pricing

DancingDinsosaur along with other mainframe analysts recently listened to Ray Jones, IBM Vice President, z Systems Sales go through the new z13 software pricing. In short, expect major new structural enhancements coming in the first half of 2015. Of particular interest will be two changes IBM is instituting:

  1. IBM Collocated Application Pricing (ICAP), which lets you run your systems the way that make sense in your organization
  2. Country Multiplex Pricing, an evolution of Sysplex pricing that allows for greater flexibility and simplicity which treats all your mainframes in one country as a single sysplex.

Overall, organizations running the z under AWLC should see a 5% discount on average.

But first let’s take a moment to review AWLC (Advanced Workload License Charge). This monthly program from the start has been intended to allow you to grow hardware capacity without necessarily increasing software charges. Most organizations under AWLC can grow hardware capacity without necessarily increasing software charges. In general you’ll experience a low cost of incremental growth and you can manage software cost by managing workload utilization and deployment across LPARs and peak hours.

A brief word about MSU. DancingDinosaur thinks of MSU as mainframe service unit. It is the measurement of the amount of processing or capacity of your mainframe. IBM determines the MSU rating of a particular mainframe configuration by some arcane process invisible to most of us. The table above starts with MSU; just use the number IBM has assigned your z configuration.

OK, now we’re ready to look at ICAP pricing. IBM describes ICAP as the next evolution of z Systems sub-capacity software pricing. ICAP allows workloads to be priced as if in a dedicated environment although technically you have integrated them with other workloads. In short, you can run your systems and deploy your ICAP workloads the way you want to run them. For example, you might want to run a new anti-fraud app or a new instance of MQ and do it on the same LPAR you’re running some other workload.

ICAP is for new workloads you’re bringing onto the z. You have to define the workloads and are responsible for collecting and reporting the CPU time. It can be as simple as creating a text file to report it. However, don’t rush to do this; IBM suggested an ICAP enhancement to the MWRT sub-capacity reporting tool will be coming.

In terms of ICAP impact on pricing, IBM reports no effect on the reported MSUs for other sub-capacity middleware programs (adjusts MSUs like an offload engine, similar to Mobile Workload Pricing for z/OS). z/OS shops could see 50% of the ICAP-defining program MSUs will be removed, which can result in real savings. IBM reports that ICAP provides a price benefit similar to zNALC for z/OS, but without the requirement for a separate LPAR. Remember, with ICAP you can deploy your workloads where you see fit.

For Country Multiplex Pricing a country multiplex to IBM is the collection of all zEnterprise and later machines in a country, and they are measured like one machine for sub-capacity reporting (applicable to all z196, z114, zEC12, zBC12, and z13 machines). It amounts to a new way of measuring and pricing MSUs, as opposed to aggregating under current rules. The result should be flexibility to move and run work anywhere, the elimination of Sysplex pricing rules, and the elimination of duplicate peaks when workloads move between machines.

In the end, the cost of growth is reduced with one price per product based on growth anywhere in the country. Hardware and software migrations also become greatly simplified because Single Version Charging (SVC) and Cross Systems Waivers (CSW) will no longer be relevant.  And as with ICAP, a new Multiplex sub-capacity reporting tool is coming.

Other savings also remain in play, especially the z/OS mobile pricing discounts, which significantly reduces the level at which mobile activity is calculated for peak load pricing. With the expectation that mobile activity will only grow substantially going forward, these savings could become quite large.

IBM z13 Chip Optimized for Top Enterprise Performance

January 23, 2015

With the zEC12 IBM boasted of the fastest commercial chip in the industry. It is not making that boast with the z13. Instead, it claims a 40% total capacity improvement over the zEC12. The reason: IBM wants the z13 to excel at mobile, cloud, and analytics as well as fast extreme scale transaction processing. This kind of performance requires optimization up and down the stack; not just chip speed but I/O processing, memory access, instruction tweaks, and more.

 z13 mobile

Testing mobile transactions on the z13

This is not to suggest that the machine is not fast.  It is.  Timothy Prickett Morgan writing in his 400 blog notes that the z13 chip runs a 22 nm core at 5 GHz, half a GHz slower than the zEC12. The zEC12 processor, the one touted as the fastest commercial processor, was a 32nm core that clocked at 5.5 GHz.  Still, the z13 delivers about a 10 percent performance bump per core thanks, he writes, to other tweaks in the core design, such as better branch prediction and better pipelining in the core. The slightly slower clock speed reduces heat.

Up and down the stack IBM has been optimizing the z13 for maximum performance.

  • 2X performance boost for cryptographic coprocessors
  • 2X increase in channel speed
  • 2X increase in I/O bandwidth
  • 3X increase in memory capacity
  • 2X increase in cache and a new level of cache

At 5 GHz, the z13, given all the enhancements IBM has made, remains the fastest. According to IBM, it is the first system able to process 2.5 billion transactions a day, equivalent of 100 Cyber Mondays every day of the year.  Maybe even more importantly, z13 transactions are persistent, protected, and auditable from end-to-end, adding assurance as mobile transactions grow to an estimated 40 trillion (that’s trillion with a T) mobile transactions per day by 2025.

Given that mobile is shaping up to be the device of the future the z13 is the first system to make practical real-time encryption of all mobile transactions at any scale, notes IBM. Specifically, the z13 speeds real-time encryption of mobile transactions to help protect the transaction data and ensure response times consistent with a positive customer experience.  With mobile overall, the machine delivers up to 36% better response time, up to 61% better throughput, and up to 17% lower cost per mobile transaction. And IBM discounts transactions running on z/OS.

To boost security performance the machine benefits from 500 new patents including cryptographic encryption technologies that enable more security features for mobile initiated transactions. In general IBM has boosted the speed of encryption up to 2x over the zEC12 to help protect the privacy of data throughout its life cycle.

Combined with the machine’s embedded analytics it can provide real-time insights on all transactions. This capability helps enable an organization to run real-time fraud detection on 100 percent of its business transactions.  In terms of analytics, the machine deliver insights up to 17x faster at 13x better price performance than its competitors.

Further boosting performance is the increase of memory in the machine. For starters, the machine can handle up to 10 TB of memory onboard to help with z/OS and Linux workloads. To encourage organizations to take advantage of the extra memory IBM is discounting the cost of memory. Today memory runs $1500/GB but organizations can populate the z13 with new memory starting at $1000/GB. With various discounts you can get memory for as little as $200/GB.

So what will you do with a large amount of discounted memory? Start by running more applications in-memory to boost performance.  Do faster table scans in memory to speed response or avoid the need for I/O calls. Speed sorting and analytics by doing it in memory to enable faster, almost real-time decision making. Or you can run more Java without increasing paging and simplify the tuning of DB2, IMS and CICS. Experience 10x faster response time with Flash Express and a 37% increase in throughput compared to disk.

As noted above IBM optimized just about everything that can be optimized. It provides 320 separate channels dedicated just to drive I/O throughput as well as performance goodies only your geeks will appreciate like simultaneous multithreading (SMT), symmetric multiprocessing (SMP), and single instruction, multiple data (SIMD). Overall about 600 processors (in addition to your configurable cores) speed and streamline processes throughout the machine.

Mainframes have the fastest processors in the industry –none come close–and with the addition of more memory, faster I/O,  and capabilities like SMT and SIMD noted above, the z13 clearly is the fastest. For workloads that benefit from this kind of performance, the z13 is where they should run.

IBM’s z13 Redefines Mainframe Performance, Economics, and Versatility

January 14, 2015

With the introduction of the new IBM z13, the latest rev of the 50-year old mainframe product line introduced today, it will be hard for IT people to persist in the mistaken belief that the mainframe can’t handle today’s workloads or that it is too expensive. Built around an 8 core, 22nm processor, the IBM z13’s 141 configurable cores (any mix of CP, IFL, zIIP, ICF, SAP) delivers a 40% total capacity improvement over the zEC12.

 IBM z113

The z13 looks like the zEC12 but under the hood it’s far more powerful

The IBM z13 will handle up to 8,000 virtual enterprise-grade Linux servers per system, more than 50 per core.  Remember when Nationwide Insurance consolidated 3000 x86 servers mainly running Linux on a System z and saved $15 million over three years, a figure later revised considerably higher. They got a lot of press out of that, including from DancingDinosaur as recently as last May. With the IBM z13 Nationwide could consolidate more than twice the number of Linux servers at a lower cost and the resulting saving would be higher still.

If you consider Linux VMs synonymous with cloud services, the new machine will enable superior Cloud services at up to 32% lower cost than an x86-based cloud. It also will cost up to 60% less than Public Cloud over three years. In almost every metric, the IBM z13 delivers more capacity or performance at lower cost.

IBM delivered an almost constant stream of innovations that work to optimize performance and reduce cost. For example, it boosted single thread capacity by 10% over the zEC12. It also delivers 3x more memory to help both z/OS and Linux workloads. The more memory combined with a new cache design, improved I/O bandwidth, and compression will boost analytics on the machine. In fact, with the z13 you can do in-memory analytics if you want it.

The one thing it doesn’t do is boast the fastest commercial processor in terms of sheer speed. The zEC12 processor still is the fastest but with all the optimizations and enhancements IBM has built in the z13 should beat the z12 in handling the workloads organizations most want to run. For instance, the z13 performs 2X faster than the most common server processors, 300 percent more memory, 100 percent more bandwidth and delivers vector processing analytics to speed mobile transactions. As a result, the z13 transaction engine is capable of analyzing transactions in real time.

Similarly, simultaneous multi-threading delivers more throughput for Linux and zIIP-eligible workloads while larger caches optimize data serving. It also improved on-chip hardware compression, which saves disk space and cuts data transfer time.  Also, there is new workload container pricing and new multiplex pricing, both of which again will save money.

In addition, IBM optimized this machine for both mobile and analytics, as well as for cloud. This is the new versatility of this redefined mainframe. Last year, IBM discounted the cost of mobile transactions on the z. The new machine continues to optimize for mobile with consolidated REST APIs for all z/OS transactions through z/OS Connect while seamlessly channeling z/OS transactions to mobile devices with the MobileFirst Platform. It also ensures end-to-end security from mobile device to mainframe with z/OS, RACF, and MobileFirst products.

For analytics, IBM continues to optimize Hadoop and expand the analytics portfolio on the z13. Specifically, the massive memory capability, up to 10TB, opens new opportunities for in-memory computing. The ability to perform analytics by combining data from different data sources and do it in-memory and in real-time within the platform drives more efficiencies, such as eliminating the need for ETL and the need to move data between platforms, as had previously often been the case. Now, just use Hadoop on z to explore data there within the secure zone of the mainframe. This opens a wide variety of analytics workloads, anything from fraud prevention to customer retention.

In addition to improved price/performance overall, IBM announced Technology Update Pricing for z13, including AWLC price reductions for z13 that deliver 5% price/performance on average in addition to performance gains in software exploitation of z13. DancingDinosaur will dig deeper into the new z13 software pricing in a subsequent post.

And the list of new and improved capabilities with the z13 just keeps going on and on.  With security IBM has accelerated the speed of encryption up to 2x over the zEC12 to help protect the privacy of data throughout its life cycle.  It also extended enhanced public key support for constrained digital environments using Elliptic Curve Cryptography (ECC), which helps applications like Chrome, Firefox, and Apple’s iMessage. In addition, the z13 sports a few I/O enhancements, like the first system to use a standards based approach for enabling Forward Error Correction for a complete end-to-end solution.

Finally, IBM has not abandoned hybrid computing, where you can mix a variety of blades, including x86 Windows blades and others in the zBX extension cabinet. With the z13 IBM introduced the new Mod 004 zBX cabinet, an upgrade from the previous Mod 002 and 003.

DancingDinosaur expects the introduction of the z13 along with structural organization changes, will drive System z quarterly financial performance back into the black as soon as deliveries roll. And if IBM stays consistent with past behavior within a year or so you can expect a scaled down, lower cost business class version of the z13 although it may be not be called business class. Stay tuned; it should be an exciting year.

The Mainframe at the Heart of the Security Storm

December 18, 2014

A survey of Chief Information Security Officers (CISOs) released by IBM in early December found more than 80% of security leaders believe the challenge posed by external threats is on the rise, while 60% also agree their organizations are outgunned in the cyber war. Even mainframe shops—the zEC12 has received the highest security rating, EAL 5+ —should not get complacent. There are a lot of bad guys gunning for the data center. Just ask Sony.

 ciso study ibm 2014

At least top management is putting resources into security. Three quarters of the CISO respondents expect their security budgets to increase dramatically over the next 3-5 years. IBM is jumping in with a security paper geared specifically for mainframe shops titled Security Intelligence for Mainframe Environments.

So what are the threats keeping CISOs awake at night?  Based on the study sophisticated external threats were identified by 40% of security leaders as their top concerns. Expect the extra budget to be thrown at these threats, which will require the most organizational effort over the next three to five years, as much as regulations, new technologies, and internal threats combined, according to the IBM analysts.

Although a majority of the CISOs surveyed appear confident their mature, traditional technologies that focus on network intrusion prevention, advanced malware detection, and network vulnerability scanning will fend off outside threats, nearly half reported that deploying new security technology is the top focus area for their organization. Their top worries: data leakage, cloud security, and mobile/device security.

Some other interesting findings from the survey:

  • While concern over cloud security remains strong, still close to 90% of respondents have adopted cloud or are currently planning cloud initiatives. Of this group, most expect their cloud security budget to increase dramatically over the next three to five years.
  • Over 70% of security leaders said real-time security intelligence is increasingly important to their organization. Yet about half found areas such as data classification and discovery and security intelligence analytics have relatively low maturity and require improvement or transformation.
  • Not surprisingly, despite the growing mobile workforce, only 45% believe they have an effective mobile device management approach. According to the study, mobile and device security ranked at the bottom of the maturity list.

Although your data center provides a tempting target to attackers, it also can protect you with an effective counter-punch. That counter-punch is delivered through increasingly powerful and fast analytics, especially real-time analytics. The objective is to identify attacks as they are underway. Otherwise, you are left scrambling to close the proverbial barn door after the horses (data) have left.

This will entail systems that identify who did what and when, recognizing what’s normal behavior versus abnormal, and obtaining visibility into subtle connections between millions of data points. This requires a great deal of contextual data and the analytical means to make sense of it. And here is where you come in: your team needs to integrate mainframe data with distributed events to gain insights that apply to the entire enterprise.

In fact, IBM identifies a series of issues that put the mainframe squarely at the heart of the challenge and the solution:

  • Complexity: The mainframe is an integral component of multiple, often large and complex business services, making it difficult to identify and analyze threats.
  • Visibility: Mainframe processes, procedures and reports are often siloed, impeding cross-enterprise information sharing to combat threats. (But silos also help protect mainframe data—be selective in breaking down the silos.)
  • Compliance: Verification of compliance is frequently a manual task—with problem alerts all too often received only after a problem has occurred.
  • Cost: Mainframe management requires highly skilled administrators, who often are costly and in short supply.

You already have many of the solutions IBM recommends, like RACF, CA-Top Secret, and CA-ACF2. The mainframe security paper cited above covers the rest. Given what happened to Sony, it’s worth reading the paper closely.

IBM Brings Cloud DevOps to the Mainframe

December 3, 2014

Is your organization ready for DevOps?  It should be coming to System z data centers almost any day now, riding in on newly announced IBM cloud-based DevOps services, software, and infrastructure designed to help large organizations develop and deliver quality software faster.

IBM Launches Bluemix Garage at London's Level39

Launch of the Bluemix Garage in London

DevOps streamlines enterprise workflow by truncating the development, testing, and deployment process. It entails collaborative communications around the end-to-end enterprise workflow flow and incorporates a continuous feedback to expedite the process. DevOps evolved out of Agile methodologies over a decade ago.

Agile was intended to streamline the traditional waterfall IT development process by putting developers and business unit people and the deployment folks together to build, test, and deploy new applications fast. Agile teams would deliver agreed upon and tested functionality within a month. Each deliverable was short, addressing only a subset of the total functionality. Each was followed by the next containing yet more functionality. In the process, previously delivered functionality might be modified or replaced with a new deliverable.

IBM is streamlining the process further by tapping into the collaborative power of the company’s Cloud portfolio and business transformation experience to speed the delivery of software that supports new models of engagement.  To be clear, IBM definitely is not talking about using DevOps with the organization’s systems of record—the core transaction systems that are hallmark of the z and the heartbeat of the enterprise. The most likely candidates will be systems of engagement, systems of innovation, and analytics systems.  These are systems that need to be delivered fast and will change frequently.

According to IBM software-driven innovation has emerged as a primary way businesses create and deliver new value to customers. A survey of 400 business and IT executives by the IBM Institute for Business Value showed businesses that are more effective at software delivery are also more profitable than their peers nearly 70 percent of the time. DevOps provides a way for businesses to remain competitive, applying lean and agile principles to software development to speed the delivery of software that meets new market requirements.

Agile represented a radical departure from the waterfall process, which called for developers to take a full set of business requirements, disappear to two years, and return with a finished application that worked right.  Except that it often took longer for the developers to return with the code and the application didn’t work as promised. By then the application was well over budget and late.  System z shops know this well.

DevOps today establishes a continuous, iterative process flow between the development team and the deployment group and incorporates many Agile concepts, including the active involvement of the business people, frequent testing, and quick release cycles. As the IBM survey noted  DevOps was spurred by the rise of smartphones and mobile computing. Mobile users demand working functionality fast and expect frequent updates. Two-year release cycles were unacceptable; competitors would be out with newer and better apps long before.  Even six-month release cycles seem unresponsive. This is one of the realities DevOps addresses.  Another reality is extreme scaling, something z data centers understand.

According to IBM, the company’s new DevOps Innovation Services help address the challenge of scaling development, enabling enterprises to shorten their software delivery lifecycle. The hybrid cloud services combine IBM’s industry expertise from hundreds of organizational change and application development projects with the industry’s leading application development portfolio, especially Bluemix, IBM’s open DIY cloud PaaS platform. They also apply the flexibility of IBM’s enterprise-grade, hybrid cloud portfolio, which was recently ranked by Synergy Research Group as the leading hybrid and private cloud for the enterprise. These services are based on SoftLayer, IBM’s cloud infrastructure platform.

In a second DevOps-related announcement last month IBM described an initiative to bring a greater level of control, security and flexibility to cloud-based application development and delivery with a single-tenant version of Bluemix. The new initiative enables developers to build applications around their most sensitive data and deploy them in a dedicated cloud environment to help them capture the benefits of cloud while avoiding the compliance, regulatory and performance issues that are presented with public clouds. System z shops can appreciate this.

Major enterprise system vendors like IBM, EMC, Cisco, and Oracle are making noises about DevOps. As far as solid initiatives IBM appears far ahead, especially with the two November announcements.

New IBM Initiatives Speed System z to Hybrid Cloud and IoT

November 20, 2014

Cloud computing, especially hybrid cloud computing, is going mainstream. Same is happening with the Internet of Things (IoT).  For mainframe shops unsure of how to get there IBM promises to speed the journey with the two recent initiatives.

Let’s start with hybrid clouds and the z. As IBM describes it, enterprises will continue to derive value from the existing investments in IT infrastructure while looking to the cloud to bolster business agility. The upshot: organizations increasingly are turning to hybrid clouds to obtain the best of both worlds by linking on-premises IT infrastructure to public cloud.

To that end, IBM has designed and tested various use cases around enterprise hybrid architecture involving System z and SoftLayer. These use cases focus on the relevant issues of security, application performance, and potential business cost.

One scenario introduces the cloud as an opportunity to enrich enterprise business services running on the z with external functionality delivered from the cloud.

hybrid use case

Here a retail payment system [click graphic to enlarge] is enriched with global functionality from a loyalty program that allows the consumer to accumulate points. It involves the z and its payment system, a cloud-based loyalty program, and the consumer using a mobile phone.

The hybrid cloud allows the z data center to maintain control of key applications and data in order to meet critical business service level agreements and compliance requirements while tapping the public cloud for new capabilities, business agility, or rapid innovation and shifting expenditure from CAPEX to OPEX.

Since the z serves as the data backbone for many critical applications it makes sense to connect on-premises System z infrastructure with an off-premises cloud environment. In its paper IBM suggests the hybrid architecture should be designed in a way that gives the businesses the flexibility to put their workloads and data where it makes most sense, mixing the right blend of public and private cloud services. And, of course, it also must ensure data security and performance. That’s why you want the z there.

To get started check out the uses cases IBM provides, like the one above. Already a number of organizations are trying the IBM hybrid cloud: Macy’s, Whirlpool, Daimler, and Sicoss Group. Overall, nearly half of IBM’s top 100 strategic outsourcing clients already implementing cloud solutions with IBM as they transition to a hybrid cloud model.

And if hybrid cloud isn’t enough to keep you busy, it also is time to start thinking about the IoT. To make it easier last month the company announced the IBM Internet of Things Foundation, an extension of Bluemix. Like Bluemix, this is a cloud service that, as IBM describes it, makes it possible for a developer to quickly extend an Internet-connected device such as a sensor or controller into the cloud, build an application alongside the device to collect the data, and send real-time insights back to the developer’s business. That data can be analyzed on the z too, using Hadoop on zLinux, which you read about here a few weeks ago.

IoT should be nothing new to System z shops. DancingDinosaur discussed it this past summer here. Basically it’s the POS or ATM network on steroids with orders on magnitude more complexity. IDC estimates that by 2020 there will be as many as 28 billion autonomous IoT devices installed. Today it estimates there are nine billion.

Between the cloud, hybrid clouds, and IoT, z data centers will have a lot to keep them busy. But with IBM’s new initiatives in both areas you can get simple, highly secure and powerful application access to the cloud, IoT devices, and data. With the IoT Foundation you can rapidly compose applications, visualization dashboards and mobile apps that can generate valuable insights when linked with back office enterprise applications like those on the z.
