What is SCA?

SCA - Service Component Architecture, which is a specification backed by a growing number of leading industry vendors (http://www.OSOA.org) and being standardized at OASIS, the international open standards consortium . SCA is:

• language-neutral
• component model 
• assembly model

SCA terminologies:

• Composite: deployment unit
• Service: entry-point into composite
• Component: provides logic
• Reference: refers to external services
• Wire: connects services, components and references – no special semantic.

SOA Composite:

• SOA composite is a standards-based deployment unit
• Leverages the SCA assembly model
• Can mix variety of components: Mediator, BPEL, Human Workflow, etc.
