1.1.4 Manifests
- The Twelve-Factor App
- The Reactive Manifesto
- The API Mandate by Jeff Bezos
- 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 allowed is via service interface calls over the
network.
- It doesn’t matter what technology they use. HTTP, Corba,
Pubsub, custom protocols – doesn’t matter. Bezos doesn’t care.
- 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.
- Anyone who doesn’t do this will be fired.
- Thank you; have a nice day!

- RAML - RESTful API Modeling Language (RAML) makes it easy to manage the whole API lifecycle from design to sharing. It’s concise - you only write what you need to define - and reusable. It is machine readable API design that is actually human friendly.
- Swagger - Design is the foundation of your API development. Swagger makes API design a breeze, with easy-to-use tools for developers, architects, and product owners.
