Microservices are one of the most recent and prominent trends in software development and architecture. Nowadays, applications are designed as a set of loosely-coupled services in microservice architecture. These "micro" services are expected to be developed independently, and they focus on a small subset of business functionalities.

Therefore, it is inevitable for competitive organizations to engage in microservice architecture.
