What is SCA?

SCA - Service Component Architecture, which is a specification backed by a growing number of leading industry vendors ( 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.
