We can focus on building services and supporting flexible composition of services and essentially we get the benefits of integration as a result of service composition.
Ron Schmelzer, a consultant with analyst firm ZapThink, just made a disturbing observation — the pool of new vendors in the enterprise software space seems to be drying up altogether.
It’s important to realize that SOA is really a rather loose collection of best practices. It’s not necessarily a well-defined list where you have some checklist of things to do SOA and if you miss one, you’re not doing SOA.
Acceleration is certainly a huge part of the value, But if we’re looking at the XML message.
EAs need to become wholeheartedly selfish: meet the requirements of the business in an agile manner by reducing the penalty for failure. In such an environment, startup solutions are not only feasible, but very appropriate.
“As their customers started figuring out that SOA success didn’t depend on buying new software after all, but rather was a better way to organize existing IT assets, now cloud computing may replace the need to own those assets altogether.”

The platform vendors are running scared. They were caught by surprise by the SOA debacle, and now they see the same writing on the Cloud Computing wall. As their customers started figuring out that SOA success didn’t depend on buying new software after all, but rather was a better way to organize existing IT assets, now Cloud Computing may replace the need to own those assets altogether. Imagine a world where <a href=”http://www.zapthink.com/2009/10/28/is-there-a-future-for-enterprise-software/”>enterprises no longer purchase software at all</a>! Why bother, when they can rent it on the Cloud, pay as they go, and never have to worry about maintaining or upgrading the big packages that have kept the vendors’ stock prices up for so long?
SOA builds on computer engineering approaches of the past to offer an architectural approach for enterprise systems, oriented around the offering of services on a network of consumers. A focus of this service-oriented approach is on the definition of service interfaces and predictable service behaviors. A set of industry standards, collectively labeled “Web Service” standards in this paper, provide and implement the general SOA concept and have become the predominant set of practical tools used by enterprise engineers for current SOA projects. Some Web Service standards have become foundational and more widely adopted, while many are still seeking broad industry or Government acceptance.
Using a Service-Oriented Architecture (SOA) approach allows organizations to become both more efficient in meeting their current needs and more agile in meeting future—and possibly unknown—challenges. SOA, however, is not a panacea. As with any large-scale systems integration effort, there are challenges with employing SOA techniques effectively. This article presents industry best practices to deal with key SOA challenges.
