It is often said that SOA is dead simply because it does not appear to have been adopted in any great way by many enterprises but nothing could be further from the truth.
We need to consider here that enterprises change very very slowly for good reasons. They have systems running for many years that have served them very well. Many have learned through painful experience that making quick changes can costs millions in lost business and productivity through systems working slowly or not being available.
The point is that 2, 3 or even 5 years in the IT cycle of an enterprise is not a huge amount of time. Many will IPL (reboot to readers unfamiliar with this term) their enterprise systems (normally large mainframes) only once or twice a year which may surprise many people who see Windows and Linux as being the be all and end all of computing and a regular reboot as being a fact of life. Many enterprises have adopted a SOA approach over the years already so SOA is really just a new term for what they have been doing before it was called SOA.
Many enterprises have been using services for many years and will continue to align these with the external services provided via the Web and other new channels over time and more than likely even when someone has come up with some new term for it. The SOA Gateway is a simple way of introducing a SOA structure into your enterprise.
