Oracle CEO Larry Ellison has admitted that the rate of SOA adoption is slow but said that the emergence of the technology offered an opportunity for the company.

Ellison said he had read news articles about the slowing adoption of SOA but stressed that SOA required a change in architecture, which takes time to implement.

"While I've read [these articles], people have to understand when you have a fundamentally new computer software architecture, SOA, it takes a long time for adoption," Ellison said. Moving to SOA is not as easy as flipping a switch, he said.
