Server farms full of Unix or Windows NT servers have proliferated over the past few years. The first few servers installed were cost-effective, but as the server farms grew, so did their complexity. Server farms consume a lot of space and power, and their operating costs multiply with each new server added.

By migrating to Linux, your company can garner some real savings in operating costs by consolidating your server farms back to the mainframes those servers were supposed to replace long ago. A single IBM mainframe can run Linux alongside existing data and applications, or support hundreds of Linux virtual machines.

Enterprise-grade middleware is now available for Linux for zSeries. Mission-critical applications implemented on Linux can now be integrated with legacy applications and databases on the native z/OS mainframe applications. For example:

WebSphere Application Server can support Java-based Web applications in a Linux partition or on a Linux virtual machine on the mainframe.

DB2 Universal Database provides a relational database in a Linux partition or on a Linux virtual machine on the mainframe, just like DB2 UDB for Unix or Windows NT.

WebSphere Commerce can support e-business commerce applications running on Linux on a highly scalable mainframe.

DB2 Connect, IMS Connect, CICS Transaction Gateway and WebSphere MQ all allow integration and interoperation between applications running in Linux partitions on one side and existing data and applications running on the native z/OS of the mainframe.
