Benefits
While the IBM Mainframe has great performance, it can also be very expensive due to high hardware and software licensing costs. A common objective for all IBM Mainframe users—large or small—is cost reduction. The biggest cost savings for all z System Mainframe users will be delivered by offloading MSUs from GPP to lower cost alternatives. Systems such as the Integrated Facility for Linux (IFL) or Distributed Systems—x86, POWER, SPARC—are often faster and much lower in cost.
The unit cost per MSU decreases as the MSU capacity utilized increases, while optimizing MSU usage releases MSUs for other processing, reducing TCO accordingly. The typical yearly IBM MLC software cost for an about 100 MSU z/OS user will be about $1.25 million. For an about 500 MSU user, the cost would be about $5 million. Reducing MSU resource optimization by about 5–10 percent clearly delivers worthwhile cost savings.
Reliable
Reducing cost while maintaining performance is a requirement for all IBM z System Mainframe users. At Proximal Systems Corporation, we have created a solution that will save your business money, while remaining at least as reliable as the Mainframe. The result is a unified computing complex, where various tasks can be easily migrated between computing systems for cost and processing efficiency, while still being able to interoperate as if hosted on the same system.
However a z System Mainframe user chooses to deploy the Proxy Coupling Technology, the fundamental platform choice is maintained; the z System Mainframe and its related Operating System remain as the underlying architecture.
The fact that the proxy task maintains the same interface as the application being replaced is crucial. Many past IBM Mainframe migration projects have failed due to fatal interoperability problems between the IBM Mainframe and Distributed Systems. Should the proxy Distributed Systems platform not be readily available for whatever reason, the Proxy Coupling Technology will default to native z System Mainframe usage.
Accessible
Quite simply, the Proxy Coupling Technology is an agnostic and open solution that can be deployed for any application software code that has z System and Distributed Systems runtime interoperability. Your business can maintain its application investment and associated ecosystem, while your process will run as if nothing has changed and you save money and maintain reliability.
