I’ve been asked a number of times recently by industry peers and technology journalists about “virtualization” as it relates to SOA.
Well, there are in fact at least 3 distinct ways that you can use virtualization concepts in SOA, so I think that it would be good for me to give you a definition of those three, and then in the next few days I will blog on each one of them independently.
Rich Seeley recently interviewed me for a SearchWebServices.com article on the first and most often mentioned type of virtualization I’ll introduce -- which is hardware virtualization. This is not a SOA specific thing. This is when you’re running many copies of the operating system within one physical hardware device so that you can get independence of those several virtual machines from each other -- from a configuration, app server and operating system point of view, but leveraging one piece of hardware to do that. I’m going to talk about why you do that in a future blog.
