This document summarizes application server platforms used by Utah state government and provides recommendations for migrating systems. It finds that the most common application servers include BEA WebLogic, JBOSS, Microsoft IIS, Oracle Application Server, Sun Java Studio, Sybase, and WebSphere. It recommends migrating selected servers to the Java EE5 version, creating a Glassfish test environment, and establishing Glassfish as the new standard if testing succeeds. It also recommends organizing an enterprise support team for application servers.

2. Introduction Application server platforms are one of the most important categories of application platform software for the State. An application server platform is infrastructure software for building Web and composite applications and, increasingly, applications based on service-oriented architecture (SOA) design principles. An application server platform integrates an application server, which manages user requests, data access, and business logic, with portal servers and integration/business process management (BPM) servers. Integration with Enterprise Service Bus environments and other specialized services are also often available. Much of what has been done with application orchestration takes place within application server platforms.
