#SOA Manifesto

In 2002, Jeff Bezos (CEO of Amazon), issued a mandate requiring all teams to expose their data and functionality through services interfaces. Jeff Bezos understood that in order for his company to be successful, he had to switch focus from creating a "perfect product" to creating a perfect platform for that product.

He mandated that:

  • All teams will henceforth expose their data and functionality through service interfaces
  • Teams must communicate with each other through these interfaces
  • There will be no other form of interprocess communication allowed: no direct linking, no direct reads of another team's data store, no shared-memory model, no back-doors whatsoever. The only communication is via service interface calls over the network.
  • It doesn't matter what [API protocol] technology you use
  • Service interfaces, without exception, must be designed from the ground up to be externalizable. That is to say, the team must plan and design to be able to expose the interface to developers in the outside world. No exceptions.
