In a recent post, David Linthicum does a bit of ranting about the long term memory of IT integration professionals by pointing out that much of what we currently think of as "new" technology and practice is really something old. Specifically, he points out that siloed systems of data can be integrated in place using "the old integration concepts of replication and abstraction".
It seems we don't hear the term "abstraction" much these days (certainly not in industry press), but I'm reminded of a computer science professor of mine (yes, despite drifting to marketing I do have a degree in C.S.) who said that computer science is the science of abstraction.
Instead, what we hear now is lots and lots of talk about "virtualization". As I think about why this is I can't escape the conclusion that this new trend and technology for virtualization is really just the notion of abstraction applied to discrete things in the IT world - disk storage and server blades. All well and good!
David Linthicum reminds us, though, that abstraction, er, virtualization can be applied to disparate instances of data sources as well to achieve much needed data integration through "virtual logical databases". So add a new flavor of virtualization to your list of important "new" technologies - real-time data virtualization. And stay tuned here for more announcements about new middleware-based solutions for bringing the benefits of virtualization to instances of data themselves!
