Complex or not complex – that is the question

Microservices can be simple, complicated, or complex, and if we do not understand them, we can fall into chaos. So, we can then use a process—or rather, a framework— to help us to decide whether we are dealing with a simple, complicated, or complex situation in order to determine what type of microservice we are building and what level of effort and resources we will need to build that service, be it people, time, or effort. We can determine whether we can buy something off the shelf for simple situations, or we can implement an existing framework. We can also determine whether we need to involve an expert to tell us which frameworks and tools we need and how to configure such tools. Finally, we can determine whether we are dealing with a complex problem and, if so, we need to assign the best people, resources, and efforts to build our microservice.

The following diagram illustrates that different microservices...
