How OpenStack is designed?

Amazon rules• 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 inter-process 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 allowed is via service interface calls over the network.

Amazon rules

• It doesn’t matter what technology they use.

• All 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.

–Jeff Bezos, Amazon Founder and CEO
