Laurianne McLaughlin over at CIO.com Virtualization Drilldown posted a story up on June 30 that has me thinking about multiple-vendor virtualization environments. Is this something that is pervasive in today's environments of vendor consolidation? Why would you be running multiple virtualization environments anyway? I can see testing out XenServer, Hyper-V, but all three at once in a production environment? I just don't see it.

With all of the environments I've run into, companies are standardizing on one vendor in the server hardware space. Not that they don't look or test out others, but it's hard to replace an incumbent vendor for something completely new. I'm not saying that there aren't scenarios for multiple-vendor relationships, like Citrix and VMware, or Citrix and Hyper-V, etc. with the products of each vendor adding value to the overall solution. John Suit, CTO of Fortisphere makes his point with this here:
"1. Define what cross-platform and cross-OS solutions you need.
For instance, Suit says, are you considering keeping VMware for servers but using some Citrix technology for virtual desktops? Does your shop require Microsoft in certain spots, but perhaps not in as many as was the case in the past? Think about what technology fits where naturally in your virtualized environment, he says."
Now what does the future hold? As Laurianne points out in her article, the Open Virtualization Format (OVF) an open industry specification in development now, is designed to support movement of a VM between platforms. I can see this really opening up the ability to move VMs around, but it still begs the question, why?
