Service Oriented Architecture (SOA) promises a great leap forward in the re-use of applications by simplifying application composition. The technology that simplifies application composition is Service Component Architecture (SCA). SCA is an open component architecture for wiring services together to build composite applications.
WebSphere Enterprise Service Bus provides the on-ramp and off-ramp to incorporate many different applications and services into an SOA solution.
In this IBM Redbooks publication we introduce SCA and how it has evolved from earlier application integration architectures. We explain how WebSphere ESB connects applications and components to the service bus by using adapters and other types of SCA imports and exports.
Our main focus is helping you sort through the many choices that need to be made when deciding how to connect applications together to meet the requirements of a business scenario. We propose six different solution patterns, each with alternative implementations to choose from, to take on most integration scenarios. We also provide seven worked examples of some of the alternatives, which are fully described in the text, and are also available as working samples from the ITSO Redbooks Web site.
