SoftLayer Direct Link Brings Hybrid Cloud to System z and Power

June 26, 2014

Back in February, IBM announced that SoftLayer was integrating IBM Power Systems into its cloud infrastructure, a move that promised to deliver a level and breadth of services beyond what has traditionally been available over the cloud. Combined with new services and tools announced at the same time, this would help organizations deploy hybrid and private cloud environments.

Back then IBM included the System z in the announcement as well by bolstering its System z cloud portfolio with IBM Wave for z/VM. IBM Wave promises to provide rapid insight into an organization’s virtualized infrastructure with intelligent visualization, simplified monitoring and unified management. Specifically, Wave helps the organization more easily manage large numbers of virtual machines.

Now it is June, the snow has finally melted and IBM’s SoftLayer is introducing Direct Link to the computing public. Direct Link had previously been available to only a select few customers. Direct Link, in effect, is a specialized content delivery network for creating hybrid clouds. Organizations would connect their private IT infrastructure to public cloud resources by going directly to the SoftLayer platform, which streamlines delivery over the network. Direct Link users avoid the need to traverse the public Internet.

The focus here is on hybrid clouds. When an organization with a private cloud, say a mainframe hosting a large amount of IT resources and services behind the firewall, needs resources such as extra capacity or services it doesn’t have, it can turn to the public cloud for those extra resources or services. The combination of the private cloud and tightly connected public cloud resources form a hybrid cloud.  If you’re attending a webinar on hybrid clouds at this point the speaker usually says …and then you just punch out to the public cloud to get x, y, or z resource or service. It always sounds so simple, right?

As far as the System z goes, SoftLayer was not actually integrated with the z in the February announcement, although DancingDinosaur expects it will be eventually if IBM is serious about enterprise cloud computing. For now, the z sits in the on-premise data center, a private cloud so to speak. It runs CICS and DB2 and all the systems it is known for and, especially, security. From there, however, it can connect to an application server, dedicated or virtual, on the SoftLayer Cloud Server to form a Hybrid System z-Enterprise Cloud. As presented at SHARE this past spring, the resulting Hybrid System z-Cloud Enterprise Architecture (slides 46-49) provides the best of both worlds, secure transactions combined with the dynamics of the cloud.

Direct Link itself consists of a physical, dedicated network connection from your data center, on-premise private cloud, office, or co-location facility to SoftLayer’s data centers and private network through one of the company’s 18 network Points of Presence (PoPs) around the world. These PoPs reside within facilities operated by SoftLayer partners including Equinix, Telx, Coresite, Terremark, Pacnet, InterXion and TelecityGroup, which provide access for SoftLayer customers, especially those with infrastructure co-located in the same facilities.

Direct Link, essentially an appliance, eliminates the need to traverse the public Internet to connect to the SoftLayer private network. Direct Link enables organizations to completely control access to their infrastructure and services, the speed of their connection to SoftLayer, and how data is routed. In the process, IBM promises:

  • Higher network performance consistency and predictability
  • Streamlined and accelerated workload and data migration
  • Improved data and operational security

If you are not co-located in any of the above facilities operated by one of SoftLayer’s POP partners then it appears you will have will to set up an arrangement with one of them. SoftLayer promises to hold your hand and walk you through the set up process.

When you do have it set up Direct Link pricing appears quite reasonable. Available immediately, Direct Link pricing starts at $147/month for a 1Gbps network connection and $997/month for a 10Gbps network connection.

According to Trevor Jones, writing for Tech Target, IBM’s pricing undercuts AWS slightly and Microsoft’s by far. Next month Microsoft, on a discounted rate for its comparable Express Route service, will charge $600 per month for 1 Gbps and $10,000 for 10 Bbps per month. Amazon uses its Direct Connect service priced at $0.30 per hour for 1 Gbps and 10 Gbps at $2.25 per hour.

Your System z or new Power server integrated with SoftLayer can provide a solid foundation for hybrid cloud nirvana. Just add Direct Link and make arrangements with public cloud resources and services. Presto, you have a hybrid cloud.

BTW, IBM Enterprise 2014 is coming in Oct. to Las Vegas. DancingDinosaur expects to hear a lot of the z and Power, SoftLayer, and hybrid clouds there.

Best System z TCO in Cloud and Virtualization

May 1, 2014

IBM recently analyzed various likely customer workload scenarios and found that the System z as an enterprise Linux server could consistently beat x86 machines in terms of TCO.  The analysis, which DancingDinosaur will dig into below, was reasonably evenhanded although, like automobile mileage ratings, your actual results may vary.

DancingDinosaur has long contended that the z Enterprise Linux Server acquired under the deeply discounted IBM System z Solution Edition program could beat comparable x86 based systems not only in terms of TCO but even TCA. Algar, a Brazilian telecom, acquired its initial z Enterprise Linux server to consolidate a slew of x86 systems and lay a foundation for scalable growth. It reports cutting data center costs by 70%. Nationwide Insurance, no newcomer to mainframe computing, used the zEnterprise to consolidate Linux servers, achieving $46 million in savings.

The point: the latest IBM TCO analyses confirm what IBM and the few IT analysts who talk to z customers have been saying for some time. TCO advantage, IBM found, switches to the z Enterprise Linux Server at around 200 virtual machines compared to the public cloud and a bit more VMs compared to x86 machines.

IBM further advanced its cause in the TCO/TCA battle with the recent introduction of the IBM Enterprise Cloud System. This is a factory-built and integrated system—processor, memory, network, IFLs, virtualization management, cloud management, hypervisor, disk orchestration, Linux OS—priced (discounted) as a single solution. IBM promises to deliver it in 45 days and have it production ready within hours of hitting the organization’s loading dock. Of course, it comes with the scalability, availability, security, manageability, etc. long associated with the z, and IBM reports it can scale to 6000 VMs. Not sure how this compares in price to a Solution Edition Enterprise Linux Server.

The IBM TCO analysis compared the public cloud, x86 cloud, and the Enterprise Cloud System in terms power and space, labor, software/middleware, and hardware costs when running 48 diverse (a range of low, medium, and high I/O) workloads. In general it found an advantage for the z Enterprise Cloud System of 34-73%.  The z cost considerably more in terms of hardware but it more than made up for it in terms of software, labor, and power. Overall, the TCO examined more than 30 cost variables, ranging from blade/IFL/memory/storage amounts to hypervisor/cloud management/middleware maintenance. View the IBM z TCO presentation here.

In terms of hardware, the z included the Enterprise Linux Server, storage, z/VM, and IBM Wave for z/VM. Software included WebSphere Application Server middleware, Cloud Management Suite for z, and Tivoli for z/VM. The x86 cloud included HP hardware with a hypervisor, WebSphere Application Server, SmartCloud Orchestrator, SmartCloud Monitoring, and Tivoli Storage Manager EE. Both analyses included labor to manage both hardware and VMs, power and space costs, and SUSE Linux.

The public cloud assumptions were a little different. Each workload was deployed as a separate instance. The pricing model was for AWS reserved instances. Hardware costs were based on instances in east US region with SUSE, EBS volume, data in/out, support (enterprise), free and reserved tier discounts applied. Software costs included WebSphere Application Server ND (middleware) costs for instances. A labor cost was included for managing instances.

When IBM applied its analysis to 398 I/O diverse workloads the results were similar, 49-75% lower cost with the Cloud System on z. Again, z hardware was considerably more costly than either x86 or the public cloud. But z software and labor was far less than the others. In terms of 3-year TCO, the cloud was the highest at $37 M, x86 came in at $18.3 M, and the Cloud on z cost $9.4 M. With 48 workloads, the z again came in with lowest TCO at $1 M compared to $1.6 M for x86 systems, and $3.9 M for the public cloud.

IBM kept the assumptions equivalent across the platforms. If you make different software and middleware choices or a different mix of high-mid-low I/O workloads your results will be different but the overall comparative rankings probably won’t change all that much.

Still time to register for IBM Edge2014 in Las Vegas, May 19-23. This blogger will be there hanging around the bloggers lounge when not attending sessions. Please join me there.
