We could implement user authentication and accounts by simply adding a user model and a few routes and views to the existing Notes application. While that's easy, is this what is done in a real-world production application?
Consider the high value of user identity information and the super-strong need for robust and reliable user authentication. Website intrusions happen regularly, and it seems the item most frequently stolen is user identities. To that end, we declared earlier an intention to develop a user information microservice, but we must first discuss the technical rationale for doing so.
Microservices are not a panacea, of course, meaning we shouldn't try to force-fit every application into the microservice box. By analogy, microservices fit with the Unix philosophy of small tools, each doing one thing well, which we mix/match/combine into larger tools. Another word for this is composability. While we can build a lot of useful...
