This article discusses how to transform and modernize the mainframe into an active, industry-standard participant of SOA implementations. It provides step-by-step guidelines to ensuring that the mainframe's strengths are leveraged, allowing it to become a full-fledged member of service-oriented solutions. Available technology approaches that enable the mainframe to both provide and consume Web services are also discussed. (First published in The SOA Magazine Issue VI, April 2007.)
