The Denver Water service-oriented architecture (SOA) implementation is occurring in the context of many different older applications, databases, interfaces, and machines that make up a loosely governed collection of “services.” The combination of these older and SOA services has contributed to the complexity of the Denver Water infrastructure, introducing risks that are expensive to mitigate. To address this challenge, Denver Water engaged The Confluence Group to help build a new service portfolio management tool called ServiceFolio. Based on an array of Microsoft technologies, Denver Water will use ServiceFolio to inventory current and planned services, and then to manage changes to the enterprise architecture.
