Many of today's management tools are not granular enough to work in an SOA environment, says Rich Colton, application-integration manager at engineering and construction company Washington Group International in Boise, Idaho. "That's what has been lagging. Everybody says we need to manage the infrastructure, but first I need to understand what kind of resources we're demanding out of that infrastructure," he says.

The complex nature of SOA requires more than monitoring in production networks. IT managers must apply the technology trifecta of governance, quality and management tools, industry watchers say.

"Enterprise IT managers need to understand what part of SOA they are dealing with and what part they want to manage right now. It's not often a stand-alone product situation," says Randy Heffner, a Forrester Research analyst. "Sooner or later, if you are doing strategic SOA, you will need robust SOA management; and to get comparable functionality, you may have to get a set of products, rather than just one."

So, despite the promised benefits of a services-oriented approach, the complexity of SOA environments and applications demands management tools from inception to deployment to operations and beyond. In the face of such complexity, numerous vendors -- newcomers and veterans alike -- have taken on the challenge of SOA management. Some are tackling a specific stage in an SOA project's life cycle, while others are promising to address SOA in its entirety.
