SOA Saves On Grunt Work

Who would have thought that the basic principles of loose-coupling, consistent interfaces and reuse would result in the developers doing less ‘grunt work’. Me for one.

“Doing an analysis of production support issues,” he said, “I was really amazed to find more than half the time they were working on issues relating to transactions between applications in this point-to-point environment.”

Point-to-point EAI connections caused unique problems because there was no consistency in the way integration was being done. That made it time consuming to maintain.

“Sixty percent of the time our application team was working to keep the spaghetti wet, to maintain the point-to-point contacts,” Kelly said.

Starting last fall, implementation of an SOA approach based on the webMethods Enterprise Service Bus (ESB) from Software AG has greatly reduced the maintenance tasks that kept developers from developing new applications, the CIO said.

“By moving to a robust messaging bus I could have robust interaction between applications and reuse services over and over and over for transactions between applications as well as moving data,” he said. “That greatly reduced the production support activities.”

Without an SOA environment such maintenance is a major cost for IT, Kelly said. Creating a point-to-point connection for a specific integration may at first appear to be a quick way to deal with an individual problem, but in the long term having the development staff spending the majority of their time on production support is not cost effective, he said.

Prior to the ESB implementation, the application team was spending 64 percent of its time on support issues and 36 percent of its time on value-added development.

“What’s happening now is those percentages are reversed,” Kelly said. “I’m finding now that 64 percent of the time my applications team is working on development and 36 percent of their time is spent on production support activities.”
