Run Web Services, SOA & Integration Workloads on the zIIP

Lower Costs/TCO, Improve Performance, Defer Upgrades

The value proposition of the System z Integrated Information Processor (zIIP) is compelling. Organizations that shift workloads from general purpose processors (GPs) to the less expensive and possibly faster zIIP can expand their use of certain workloads, reduce processing costs, and lower mainframe total cost of ownership (TCO). Many can also defer GP capacity upgrades, and those using all of their GP capacity may improve mainframe performance.

Of course, not all System z workloads are zIIP-eligible, as organizations reliant on CICS® know very well. Neither the CICS server nor traditional CICS applications are permitted to run on the zIIP. However, organizations that use software from licensed ISVs such as HostBridge for CICS integration – whether with other enterprise applications, SOAs, cloud architectures, or Web applications – can now zIIP-enable CICS Web services and integration/SOA workloads. And the larger their integration workloads, the greater the benefits they can realize with the zIIP.

zIIP-Enabled Integration: Two Use Cases

Two IBM and HostBridge customers provide cases in point. Like many organizations today, they continually seek ways to reduce operating costs while improving performance. Transferring CICS integration/Web services workloads from GPs to the zIIP has helped both achieve significant benefits.

A financial institution with five million customers, runs its business on a suite of CICS-based banking applications. While its GPs do not run at full capacity, the institution is interested in reducing its System z cost of ownership by shifting workloads to specialty engines. Its existing System z hardware has a zIIP installed but not utilized heavily. The institution’s customers live around the world and access the mainframe via the Internet from personal computers, tablet PCs, the latest smartphones, and ATMs in all twenty-four time zones. These millions of users execute very high volumes of transactions every day. These services-based transactions in turn represent a substantial percentage of all of the financial institution’s CICS-related processing. Today, all of it runs on the zIIP, and the institution has achieved considerable savings on processing cost and mainframe TCO.

A Department of Education in a major US city uses CICS applications to perform financial accounting. Their System z GPs run at 100% during peak processing times, and processing demand continues to grow. During peak periods, response times suffer for all workloads, and business units within the department battle over limited processing resources. The department’s Web services-based integration enables millions of educators, service providers, and parents to interact with the mainframe, so integration workloads represent a significant percentage of the total. By moving these workloads to the zIIP, the department reduced demand on its GPs and experienced performance improvements for all other System z processing, including dramatically faster response times. Equally important, the department postponed a capacity upgrade, saving even more.

HostBridge for zIIP

Both organizations use HostBridge for zIIP to zIIP-enable their integration/SOA processing. Due to its unique architecture, HostBridge software and all integration/Web services workloads that run on HostBridge are 100% zIIP-eligible. This means that any XML/Web services-based CICS integration – with applications, SOAs, clouds, or Web infrastructures – can run 100% on the zIIP. With HostBridge for zIIP – which is simply HostBridge integration software with a set of specific technologies that allow it to run according to zIIP rules – organizations can shift workloads to the zIIP and do more with CICS at substantially lower cost.
