Could be. I'm using VMware both as an individual, and as the System Admin for a small (<100 users) company where VMs are running on our servers and on our users' notebooks. I'm aware that there are big companies doing huge VM hosting applications; that's not my bag at present.
Don’t let the consultants fool you. Doing a 6,000+ application, storage and server optimization is no walk in the park. It takes a LOT of expertise and experience to make it happen without a disaster.
