Summary
At the start of the chapter, we looked at what microservices are philosophically and what their advantages are, and implemented an HTTP-oriented microservice using Flask.
We then looked at some of the advantages of process-based modularity and saw how applying those principles to web applications results in a microservice architecture. We looked at the details needed to use Flask to create a RESTful microservice and put that knowledge to use by building a simple person management microservice.
Next, we looked at using nameko's RPC mechanism to implement a microservice, which simplifies the code significantly, at the cost of requiring that we set up an AMQP infrastructure and a more difficult interface with systems outside the AMQP network.
In the next chapter, we'll look at how to interface between Python and compiled code to optimize performance bottlenecks in our code and access libraries written in other programming languages.
