    Abstract

    This IBM Redbooks publication describes how Linux can be combined with z/VM on zSeries and S/390 hardware - the mainframe. This combination of hardware and operating systems enables Internet Service Providers (ISP) and Application Service providers (ASP) to more efficiently provide services. We assume a broad definition of ASP to include production enterprise solutions as simple as file serving.

    In a world of discrete servers, when a new resource is required, workload can either be added to an existing server or a new one can be purchased. Often a new server is installed and the server farm grows in the enterprise.

    S/390 and zSeries hardware, microcode and software allow physical resources to be made virtual among Linux systems. This allows many hundreds of Linux systems to exist on a single server. Running multiple Linux images as guests of VM/ESA or z/VM is a smart choice.
