But good software engineering is not about fancy frameworks and solutions aggressively promoted by their vendors. It is not about doing something because Netflix or Google did it. It is about taking well-thought-out decisions based on facts and knowledge. That’s why it is important to be familiar basic architectural concepts like CQRS. It is...

In this article we are going to focus on service discovery, which is one of the fundamental concepts of microservice based architecture. Service discovery is a mechanism that allows services to find each others network location.
