There has been a tremendous movement in the form of virtualization on IFL's with zLinux due to the closeness (spelled performance) of data on the zOS side of the machine. This solves the security, performance, power and consolidation questions, not to mention cost.<br /><br />As an example, I have one customer (I am currently a vendor) where their first virtualization platform is zLinux on IFL's (they have 33 IFL's currently with over 800 VM's running there), then go to VMware on x86 and then if you need a physical machine, you have to justify it. They have also reduce the high cost of MIPS based licensing on the mainframe (spelled zOS here) by moving applications off of zOS (WebSphere and more) onto zLinux. <br /><br />They use this model to host internal applications as well as hosting external customers who may or may not need access to the back end data in the same model. <br /><br />So a private cloud to internal company customers and a semi public cloud/hosting model to external customers. The bottom line is the security, cost and convenience (can I get there and move it when needed) all come into play.Bruce Stanleyhttps://www.blogger.com/profile/03434879653670558573noreply@blogger.comtag:blogger.com,1999:blog-8750297140750368021.post-14821828622972925382011-07-01T09:41:03.822+01:002011-07-01T09:41:03.822+01:00Thanks so much for posting all of the awesome info...Thanks so much for posting all of the awesome info!
