Since Verspieren's core databases were already running on IBM DB2 for z/OS, the logical choice was to deploy the portals on IBM WebSphere Portal software running on the mainframe to benefit from the platform's outstanding reliability.
Dominique Bourgain, Manager of Systems and Production at Verspieren, explains: "We selected SUSE Linux Enterprise Server for z Systems and LinuxONE as the operating system, because we were confident that it would provide 24/7 availability and an excellent price-performance ratio for our mission-critical applications."
Verspieren also runs IBM Content Navigator software, designed to help staff quickly find the content they are looking for in the company's electronic document management system, on two instances of SUSE Linux Enterprise Server on the same mainframe.
The SUSE Linux Enterprise Server environment is hosted on a z/VM virtualization layer on Integrated Facility for Linux (IFL) processors on Verspieren's zEC12 server.
While the environment currently runs on three IFLs, Verspieren is planning to use all six IFLs in its mainframe to support applications once their migration from the green-screen environment is complete.
"Our SUSE Linux Enterprise Server for z Systems and LinuxONE environment is very easy to manage, allowing our IT staff to focus on more productive tasks," said Dominique Bourgain. "Linux on IBM z Systems also offers high performance and low operational costs for these applications."
"The reliability of our key business systems is extremely important to us, since our internal staff, business partners and clients rely upon them to support their day-to-day activities," said Dominique Bourgain.
"SUSE Linux Enterprise Server for z Systems and LinuxONE provides round-the-clock availability for these systems, and we have never had any problems with the environment."
Deploying portals on SUSE Linux Enterprise Server for z Systems and LinuxONE within the mainframe also enables Verspieren to keep sensitive data not only in-house, but also within the same high-security landscape as its core databases.
Running both z/OS and SUSE Linux Enterprise Server for z Systems and LinuxONE on the mainframe also enables Verspieren to avoid adding cost and complexity of investing in additional servers, helping the company maintain the low operational costs it needs to sharpen its competitive edge.
Dominique Bourgain concludes: "We selected SUSE Linux Enterprise Server for z Systems and LinuxONE as our strategic platform because it provides low costs, high performance and requires little day-to-day administration. In fact, we are moving as many of our key applications as possible onto the platform."
