However, a recent report indicates that for SOA adoption this may not be the case. As the authors point out, most of the oft-quoted SOA success stories are in Europe, Canada, Asia and Australia, with companies in these geographical areas apparently more ready to embrace SOA than their American counterparts. But what are the reasons for this? Is it, as the authors posit, that large vendors dominate the US market and create so much noise about SOA as to confuse "local" users? Or is it that EAI was so dominant in the US compared to elsewhere that it is difficult for SOA based solutions to break the strangle-hold? The only thing that appears to be globally accepted, according to the report, is that SOA has reached acceptance much faster than previous technologies.

The report discusses a number of possible reasons for European dominance of the take-up of SOA. These include that enterprise architecture as a practice is more widely respected and practiced in Europe than it is in the US.
