Apache Tuscany provides an open source services infrastructure for building SOA solutions. It's based on emerging Service Component Architecture (SCA) specifications. With the Tuscany implementation of SCA, application developers can easily create or reuse services in different languages (Java, C++, BPEL, XQuery or various scripting languages), assemble and deploy them in a distributed environment. It now becomes a reality that application developer can really focus on the business logic without being puzzled by the plumbing technologies. In this session, we will introduce the key aspects of SCA by real examples and demonstrate how simple, flexible and powerful the experience can be to develop SOA solutions with Tuscany.
