Leave a comment

Don’t tell me that you’ve never found yourself thinking about what vMA or vCO or vCAC is in a documentation, because with soo many VMware products, there is another world out there to be remembered.

Well, in that case, don’t fear, as I have collected a VMware Acronyms list for your product searching pleasure.

Hey!, and it’s a nice downloadable PDF, to boot!


But in case you need to have a quick look and don’t need to download the file, here is the list:

Acronym Full Product/Technology Name Product Description
