This battle of giants is inevitable. From my point of view both sides have solid statements. Personally I prefer Microsoft Private Cloud as I think it provides more business value. Only the time will show who will prevail but I think Microsoft are currently the leading side with System Center 2012 and with the upcoming Windows Server 2012 they will provide a very solid solution for Private Cloud. An indication that Microsoft is starting to be the leader not the follower in this area is this statement from VMware’s CTO, Dr. Stephen Herrod at a recent VMUGIT event (scroll to the YouTube video at 3:12):
“VMware Cloud Infrastructure Suite is really more of a marketing term. Those of you know our products deeply know that they don’t fit this well together as they need to. Some of them have multiple databases, some don’t look the same, some install differently, and what I can’t stand that is Site Recovery Manager doesn’t currently work with vCloud Director. So, what we are basically able to say is that we created and acquired companies that led to a lot of individual products that don’t work well enough together yet.”
This statement is important not because Dr. Herrod is pointing the flaws in their products but because in their next releases in these products they will try to integrate them together and sell them as one products a strategy which Microsoft already applied to System Center 2012.
This statement is taken from an MS article titled “The facts about the value of a Microsoft private cloud”. You can read by your self and decide which product gives more business value.
You can also try this tool http://servervirtualization.cloudapp.net/ to calculate the costs between the products. Similar tool provided by VMware can be found here: http://www.vmware.com/technology/whyvmware/calculator/.
