Just about a year ago, in an IT Business Edge 3 Questions interview, it made sense to ask an industry expert whether SOA had crossed over from the early adopter stage to the mainstream. In other words, the big SOA question at the close of 2005 was, has it arrived?
That's certainly not the case as we come to the close of 2006. SAP recently declared its intention to move 10,000 customers to SOA in the next 12 months. At this year's Oracle OpenWorld, a senior Oracle executive declared that SOA was "the standard way for customers to derive added business value from their current IT investments."
IBM, still the ultimate leader in enterprise IT, is so deeply into SOA that Gartner has declared it to be the "leading SOA market maker." And Microsoft now sponsors an SOA & Business Process Conference where, this year, it denounced the "big bang" approach to SOA favored (according to Microsoft) by the other above-mentioned companies.
Bottom line: Like it or not, SOA is here to stay.
