No enterprise data center today runs just one platform. They have Intel/Windows or some flavor(s) of UNIX/Linux as their main production systems, but they generally run a mix of platforms and operating systems, even throwing Apple, VMware, and mainframes into the mix.
Organizations end up with this mix of platforms for perfectly understandable reasons, such as acquisitions or to meet special software requirements, but it results in a certain amount of inefficiency and added cost.





Thanks for the repost of Choice of Hybrid Systems.
not a problem, I have no problem repost what I like and hope others will do the same for me.
