So CloudCamp in London on the 6th July has the tagline “Serverless and the the death of devops”. OMG folks can you please stop doing this? I really like the CloudCamp folks – it’s a fun event and a really vibrant community, but the whole “death of devops” thing really grinds my gears. I blame Simon Wardley. 😉
In orchestration, there is a controller (the ‘orchestrator’) that controls the interaction between services. It dictates the control flow of the business logic and is responsible for making sure that everything happens on cue. This follows the request-response paradigm.In choreography, every service works independently. There are no hard dependencies between them, and they are loosely coupled only through shared events. Each service listens for events that it’s interested in and does its own thing. This follows the event-driven paradigm.
