A look back

For many years the mainframe platform had been considered outdated and was the object of replacement strategies. However, as the applications, often programmed in COBOL, contain complex and critical business processes, replacement projects tend to drag on or were postponed until an unspecified date.

The replacement strategy had considerable consequences for system architectures and the staff responsible: mainframe architectures were not being modernised in accordance with technical progress, nor were staff being increased in the continuously developing technology stack.

During this time, so-called “hybrid applications” developed, whose databases and business logic are still found on the mainframe platform and whose interfaces were implemented as modern web applications on X86 servers.

Due to the development of the mainframe as a high performance platform for modern architectures and the things now being required of big data and IoT due to digitisation, “the host” is now regaining considerable significance.

A closer look

Like other IT service providers, T-Systems faces two challenges:
modernising mainframe architectures and increasing young mainframe personnel

The solution

Image
In 2017, together with PKS, T-Systems began its mainframe innovation journey.

Conclusion

Image
PKS’s comprehensive experience in modernising legacy applications and developing system architectures based on the modern mainframe technology stack, and the enthusiasm of young IT talents were combined with T-Systems’ in-depth knowledge of customer processes and architectures. The result was a forward-looking mainframe strategy called zFuture, which aims to implement a long-term innovation process.  The idea is optimum deployment of the IT budget for functional enhancements such as Java on zLinux. Excellent technology is thereby combined with optimum functionality.
