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.
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.
不管Bezos的這個指令有多傳奇,多有真知灼見,但最重要的可能是第6點:Anyone who doesn’t do this will be fired。可想而知對非軟體工程團隊的人來說,這是一個多"不合理",多勞師動眾的一個要求。但若不是Bezos的這道指令,若不是這麼強悍的執行力,Amazon就不是今天這個樣子了。
