4.4 Summary

In this chapter, we have presented two companies with typical Linux projects. ISPCompany supports the infrastructure of various customers with Linux images on the mainframe. This enables ISPCompany to offer lower rates to customers. ISPCompany grows horizontally, adding new Linux images on its mainframe.

StoreCompany, on the other hand, is integrating Linux into the fabric of its enterprise as a system for rapid deployment. Linux on the mainframe gives StoreCompany the opportunity to be very responsive to demands for new applications at a very low risk. StoreCompany will create new Linux images as new prototype projects require. Projects that succeed and grow can justify any additional IFL capacity. Projects that fail simply have their images deleted, and others can then use the resources.
