So, we had a look at what a microservice is and why structuring our servers as collection of microservices is helpful. Now, let's take a look at the practicalities and use Flask to construct a functioning microservice.
Microservices can be pretty easily divided into those that use web technologies, such as HTTP, to communicate with each other and those that use a dedicated inter-process communication or a remote-procedure-called mechanism to communicate.
There are advantages to each, depending on the specific needs of a project and neither is inherently easier to work with. However, I'm going to refer to microservices that use web technologies to communicate as high level because they are inherently closer to the level at which users operate. Conversely, I'll refer to microservices that use specialized protocols as low...
