Service Component Architecture (SCA) is a set of specifications which describe a model for developing business solutions using a Service-Oriented Architecture. One of the main goals of SCA is to provide developers with a simple methodology and programming model for creating applications and systems based on SOA.
SCA applications are composed of service components that implement business logic, offer their capabilities through service-oriented interfaces and consume functions offered by other components through service-oriented interfaces, called service references. The SCA client and implementation specification defines a programming model for implementing service components and invoking services. The SCA assembly model specification defines how you wire together and assemble components into composite applications.
SCA also allows the service implementation and service assembly to be decoupled from the details of infrastructure capabilities and the access methods used to invoke services. SCA components only need to use a minimum of middleware APIs. Infrastructure capabilities and access methods are handled declaratively through SCA policies and SCA binding profiles.
In this session, we will introduce the SCA specifications and show through coding examples how to implement services, consume services, and assemble service components. We will also show how to use SCA policies and binding profiles.
This session will explore how the Tuscany runtime works. We will work through coding examples and how to use Tuscany to implement service components, build, deploy and run composite SCA applications and communicate with Web Services. We will present how to get involved in the development of Tuscany and embed the Tuscany runtime or extend it to support additional component types, programming languages, bindings and communication protocols. We will also cover the latest developments and ongoing work with the Tuscany code base, with a demonstration of some of the latest features.
