Versioning APIs

I have blogged in the past about microservices, and the advantages that architectural style can bring. These small, focussed and, most importantly, autonomous services commonly expose their functionality via a REST interface.

Inevitably there will come a time when you need to change that interface. Yes, in an ideal world, you will come up with a perfect API first time round and it will never need to change, but requirements change or new users come on board, and we must adapt. Read on to find some approaches to dealing with changing interfaces without breaking clients.

Microservices

A microservice is a small, focused piece of software that can be developed, deployed and upgraded independently. Commonly, it exposes functionality via a synchronous protocol such as HTTP/REST.

That is my understanding of microservices, at least. There is no hard definition of what they are, but they currently seem to be the cool kid on the block, attracting increasing attention and becoming a mainstream approach to avoiding the problems often associated with monolithic architectures. Like any architectural solution, they are not without their downsides too, such as increased deployment and monitoring complexity. This post will have a look at some of the common characteristics of microservices and contrast them with monolithic architectures.
