IBM Introduces Cloud Private to Hybrid Clouds

November 10, 2017

When you have enough technologies lying around your basement, sometimes you can cobble a few pieces together, mix it with some sexy new stuff and, bingo, you have something that meets a serious need of a number of disparate customers. That’s essentially what IBM did with Cloud Private, which it announced Nov. 1.

IBM intended Cloud Private to enable companies to create on-premises cloud capabilities similar to public clouds to accelerate app dev. Don’t think it as just old stuff; the new platform is built on the open source Kubernetes-based container architecture and supports both Docker containers and Cloud Foundry. This facilitates integration and portability of workloads, enabling them to evolve to almost any cloud environment, including—especially—the public IBM Cloud.

Also IBM announced container-optimized versions of core enterprise software, including IBM WebSphere Liberty, DB2 and MQ – widely used to run and manage the world’s most business-critical applications and data. This makes it easier to share data and evolve applications as needed across the IBM Cloud, private, public clouds, and other cloud environments with a consistent developer, administrator, and user experience.

Cloud Private amounts to a new software platform, which relies on open source container technology to unlock billions of dollars in core data and applications incorporating legacy software like WebSphere and Db2. The purpose is to extend cloud-native tools across public and private clouds. For z data centers that have tons of valuable, reliable working systems years away from being retired, if ever, Cloud Private may be just what they need.

Almost all enterprise systems vendors are trying to do the same hybrid cloud computing enablement. HPE, Microsoft, Cisco, which is partnering with Google on this, and more. This is a clear indication that the cloud and especially the hybrid cloud is crossing the proverbial chasm. In years past IT managers and C-level executives didn’t want anything to do with the cloud; the IT folks saw it as a threat to their on premises data center and the C-suite was scared witless about security.

Those issues haven’t gone away although the advent of hybrid clouds have mitigated some of the fears among both groups. Similarly, the natural evolution of the cloud and advances in hybrid cloud computing make this more practical.

The private cloud too is growing. According to IBM, while public cloud adoption continues to grow at a rapid pace, organizations, especially in regulated industries of finance and health care, are continuing to leverage private clouds as part of their journey to public cloud environments to quickly launch and update applications. This also is what is driving hybrid clouds. IBM estimates companies will spend more than $50 billion globally starting in 2017 to create and evolve private clouds with growth rates of 15 to 20 percent a year through 2020, according to IBM market projections.

The problem facing IBM and the other enterprise systems vendors scrambling for hybrid clouds is how to transition legacy systems into cloud native systems. The hybrid cloud in effect acts as facilitating middleware. “Innovation and adoption of public cloud services has been constrained by the challenge of transitioning complex enterprise systems and applications into a true cloud-native environment,” said Arvind Krishna, Senior Vice President for IBM Hybrid Cloud and Director of IBM Research. IBM’s response is Cloud Private, which brings rapid application development and modernization to existing IT infrastructure while combining it with the service of a public cloud platform.

Hertz adopted this approach. “Private cloud is a must for many enterprises such as ours working to reduce or eliminate their dependence on internal data centers,” said Tyler Best, Hertz Chief Information Officer.  A strategy consisting of public, private and hybrid cloud is essential for large enterprises to effectively make the transition from legacy systems to cloud.

IBM is serious about cloud as a strategic initiative. Although not as large as Microsoft Azure or Amazon Web Service (AWS) in the public cloud, a recent report by Synergy Research found that IBM is a major provider of private cloud services, making the company the third-largest overall cloud provider.

Windows for IBM zEnterprise/zBX

April 18, 2011

Last week IBM published a general statement of direction, not an actual product announcement, that essentially said the zEnterprise will run Windows in the 4th quarter via an x blade for the zBX. The announcement reads, in part, “IBM intends to offer select IBM System x blades running Microsoft Windows in the IBM zEnterprise BladeCenter Extension Model 002.”

Along with the announcement came the usual disclaimer: “IBM’s plans, directions, and intent are subject to change or withdrawal without notice. Any reliance on these statements of general direction is at the relying party’s sole risk and will not create liability or obligation for IBM.”

This isn’t exactly new. IBM has been hinting about this since the zEnterprise announcement last July although it refrained from making any statement that might legally commit them to anything. DancingDinosaur has been writing about it for about as long. Here is a Windows on z piece from earlier this year.

Windows on z (or the zBX as is the case here) raises some interesting issues. Of immediate interest is the question of which Windows workloads might be best moved to the zEnterprise. Microsoft Exchange and Microsoft SharePoint, probably the company’s two most popular enterprise server applications, are good bets to stay where they are and not move to the z.

Similarly, the Microsoft Office Suite will stay where it is unless someone wants to attempt to virtualize a slew of Office desktops on a handful of zBX IBM x blades as a VDI play. Without knowing the performance and pricing details of the zBX System x blades it is impossible to intelligently make such decisions.

In response to which workloads, IBM’s reply is as follows: Enterprise clients with one or more applications running in a complex, heterogeneous, multi-tiered environment have the opportunity to upgrade that infrastructure with zEnterprise and enjoy the management benefits that the Unified Resource Manager brings. The most likely candidates are those Windows apps that make use of data or processing residing on the z. This is IBM’s basic fit-for-purpose strategy.

IBM also is not expecting a wholesale migration of Windows servers to the z. Again, the IBM spokesman explains: Many of the largest data centers already have far more blades and/or rack-mounted servers in their inventory than could realistically fit into the zBX.

What IBM does hope for, according to the spokesman, are workloads that rely on System z for data serving and application components, whether it is DB2 for z/OS, IMS, CICS, WebSphere, or even Oracle. In addition, they are workloads that require the strength of System z but often have application components on Power or Intel that are required to complete the end-to-end business process. Clients who have applications running in these two- or three-tier environments may be ideal candidates for zEnterprise running the new System x blades.

Beyond these basic fit-for-purpose statements IBM isn’t saying much about blade pricing, performance, or software licensing. This serves two purposes for IBM: 1) it avoids promises to which it might be held, and probably as importantly, 2) it freezes the competitive market. Multi-platform, multi-tier enterprises considering an upgrade of their Windows servers to the latest offerings from HP or Oracle (Sun) or others now know this option is coming in the fourth quarter and may wait until they see the pricing, licensing, and performance details.

With the System x blades running Windows as well as Linux IBM indeed can make a strong case for IT recentralizationg on the zEnterprise, especially for multi-tier, multi-platform enterprises. This case will be based on the zEnterprise’s centralized management efficiency, the potential for greater optimization, and the resulting performance improvements. It’s a good story that could catch on if IBM keeps the pricing competitive.

Upcoming pieces here will take up the corporate politics implications of such a recentralization effort. 

Should the IBM zEnterprise run Windows

January 3, 2011

Will the zEnterprise run Windows is a question IBM has been asked repeatedly starting almost as soon as the machine was introduced last summer, even before. It is a fair question given that the zEnterprise will support IBM x86 blades through the zBX extension cabinet, and Microsoft Windows runs on the x86 processor.

Here is the response of IBM’s Alan Altmark on July 22. to the Windows question.

Q: Will the zEnterprise System support for Microsoft Windows or IBM iOS operating systems?

A: No, Windows [and] iOS are not supported at this time. IBM will initially support AIX, Linux on System x (SOD available 1H 2011) and optimizers through the zBX. Support for additional operating systems will be evaluated over time based on demand from our clients.

DancingDinosaur also asked various IBMers the same question and got pretty much the same response: There is no technical reason the zEnterprise cannot run Windows; we’ll get to it if there is customer demand.

Will the z run Windows might not be the right question. Maybe the more important question is this: SHOULD organizations run Windows on the z? Is there a compelling business case for doing so?

Running Windows on the z will vastly increase the number of workloads organizations could run on the machine, and DancingDinosaur always welcomes new mainframe workloads. From that standpoint, it’s a no-brainer.

Licensing and pricing details of Windows on z aside, one could argue a solid business case for consolidating Windows server workloads on the z. Using Linux server consolidation on z as a guide, organizations should be able to consolidate hundreds if not thousands of virtual Windows servers on a single z. The organization would capture the savings from massive consolidation as well as achieve z levels of RAS compared to what they typically can achieve today with distributed x86 servers. (You can achieve high levels of RAS in the distributed world, but it doesn’t come cheap or easy.)

Although the business case may be advantageous, there is a political problem organizations will have to confront. Simply put, the chances are very high that any proposal to consolidate Windows apps on the z would encounter bitter resistance. Most organizations with mainframes also support distributed platforms. Data center managers already report resistance to consolidating distributed Linux severs on the mainframe. Just imagine the resistance from the Windows camp.

There are other considerations as well. To start, not every Windows server workload needs the capabilities the z brings. Some small Windows workgroup apps might not even be worth z MIPS.

The x86 blades for the zBX aren’t expected until sometime in the first half of 2011. After that there will be plenty of time to start advocating for Windows on z. Just be ready for an epic battle.
