VMware or HYPER-V or be in heterogeneous environment?

We are in the IT era of moving towards virtualization due to several factors. But from the IT business Decision makers are in the doubtful position of deciding which virtualization platform to consider. now it has become a boiling question of VMware ESX, Vsphere or Microsoft HYPER-V  v2.0.

Unfortunately for IT managers this is not a black and white question or a decision to take (at least most of them). So what the expert advise for this? Try and see both environment before moving to one platform, but this is not an easy task for busy admins. but if you carefully consider it makes real sense, most of the blogs and web sites talk about the product in biased method instead of been unbiased. Even a person who tried to be fail will be falling into biased method sine he must have been practically using one version more than the other.

The reasons for a heterogeneous environment are, well, heterogeneous. Some companies are in transition, moving their virtual environments from VMware to Hyper-V. Others choose to segment their servers according to geography or department. Still others pick their virtualization platform according to the underlying physical platform or application. As you can see moving to a vitalization platform is not all about the features but balance and reducing of the cost as well.

Most of the early virtualization adopt customers are coming from VMware background. Some are considering moving to HYPER-V  due to the software licensing cost in VMware. Some deciding keep existing VMware environment as it is and move new requirements to HYPER-V  to reduce cost and balance everything. So in that case heterogeneous environment come it picture automatically. So next question is how to manage heterogeneous environment? Well that is not that difficult as we think, since most of the ISV’s has already predict that and given solutions for that. As an example Microsoft Virtual Machine Manger (VMM 2008) is already supporting VMware ESX management as well. But of course this manageability will be depend on how the IT manger want to accept it (Hope you get what I mean 🙂 )

So cross virtualization platform is not a bad thing from my point of view. You’ll get your hands dirty on both technologies and will get the chance to evaluate them. But you may decide to move to one platform later since heterogeneous is a temporary transition period for most of the companies. So for the summarization I want to point out selecting the virtualization platform is not based on the features itself but various other factors as well.
