What is SCA?An essential characteristic of SOA is the ability to assemble new and existing services to create brand new application that may consist of different technologies. Service Component Architecture defines a 'simple' service-based model for construction, assembly and deployment of network of services (existing and new ones) that is language-neutral. SCA programming model is highly extensible. SCA can easily be extended to work with - multiple languages component implementation types including Java, C++, BPEL, PHP, Spring,...
- multiple container technologies such as Tomcat, Jetty, Geronimo, OSGI,bindings including Webservice, JMS, EJB, JSON RPC, ...
- multiple service access methods hosting environments such as RMI, Axis2Tomcat, Jetty, Geronimo, OSGI,..
SCA separates infrastructure concerns from business logic and enables developers to focus on business logic. It does this by defining ways to declaratively apply policy and qualities of service such as reliability, security, and transactions to service invocations. For more information on the various SCA specifications, please visit the OSOA website.
SCA specifications have been submitted to OASIS for consideration to become standards. Apache Tuscany implements SCA specification 1.0 in Java and C++ (referred to as Native) runtimes. Resources |
