Soa

Eight Principles

• Normalized service contract.
• Loose coupling between consumers and services, and between the services themselves.
• Abstraction from implementation details; the consumers only know the contract without worrying about implementation details.
• Ability to compose other services regardless of the complexity of the composition.
• Run-time environment autonomy.
• Statelessness.
• Reusability.
• Discoverability through meta data or public contract definitions.
