Integrated Facilities for LINUX (IFLs)
The Linux on the IBM mainframe System z9 and zSeries environment is a good, relatively inexpensive choice for high transaction applications requiring a high level of security and scalability. It can run on either z/OS or S/390 operating systems. The processing units, known as Integrated Facilities for Linux (IFLs) can be added as required to meet usage peaks and troughs.

The chief appeal is that it keeps you on your Z-Series IBM mainframe, which be honest, is where you want to be. Reliability, security and manageability are second to none and now you get all the benefits of a centralized virtual Linux open source "world" without a mess of multiple servers. Harnessing the virtualization technologies the mainframe is famous for and using Hipersockets for superfast virtual TCP/IP is really worth considering as an alternative to an ever more complex and "stressed" server to server network.

1. IFLs are significantly less expensive than z/OS CPUs on the same mainframe and the fee is one-off.
2. Your MSU rating and your zSeries model designation are unchanged when running extra Linux applications on IFLs, leaving you in the very pleasant position of owing IBM no extra charges.
3. Centralising on the mainframe rather than going for the traditional plethora of non-scalable servers reduces software, labour, network hardware and other costs. These costs savings can be significant - do not be one of the many companies and organisations that do no sufficiently take this into account.

For a detailed look at why a strategic combination of DB2 Connect and zLinux is a particularly strong proposition, take a look at the article by Paul C. Zikopoulos, BA, MBA. You will also find here useful discussion of Hipersockets technology and IBMs "On Demand" offering.

For a history and quite detailed discussion of zLinux and IFLs written in straightforward Engish you cannot do much better than go to WIKIPEDIA.
