Distributed Domain

An SCA Domain (complete runtime configuration) that is "distributed over a series of interconnected runtime nodes".

...

Provides an environment inside which SCA component instances execute. It's an operating system process, separate from other Nodes. Its form may be as simple as a single Java VM or it may take the more scalable and reliable form, such as a compute cluster.

Each node must be capable of supporting at least:

• one implementation type
• one binding type (which may be restricted to binding.sca)

A node must be able to expose the service endpoints required by the components it runs. It must be able to support the client technology for the references of associated components.
