« GT and Skyway Team Up | Main | Live from SOA Exec Forum: Verizon's SOA Architecture »

At InfoWorld's SOA Executive Forum here in sunny NYC today, there's a panel going on called SOA Reality Check, which has various top IT architects from a variety of different industries sharing their stories on their real-life experiences with SOA.

Eric Peebles, the chief application architect for the Windy City, said that Chicago's transition to SOA started about three years ago, when the CIO looked in consternation at the city's twelve different systems with about fifteen different business units and departments all over the city, all with their own IT shops.

Peebles said the CIO sat down and mapped all the different systems and business units, and "it looked like a bag of spiders. It was brittle, breaking constantly and hard to maintain."

The CIO then looked to the architecture team and asked them to find a better way. "We didn't know that was going to involve a move to SOA [at the time]," Peebles said. "We were just looking for a better way."
