TLDR
Twitter’s Fail Whale is a story of growing up with a microservices-based architecture. Twitter started with a monolithic service called Monorail, represented as a gigantic box of functionality with enormous scope. The resulting services are autonomous —like the teams who manage them—, so they can be independently deployed. Getting a microservice architecture right is quite an engineering journey, it requires discipline and patience. The Microservices Maestro (i.e. you) must orchestrate principles of separation of concerns, failure degradation, security and privacy.via the TL;DR App
