What are microservices?

Microservices are a software development style that has recently been developed to set up practices intended to increase the efficiency and speed of developing and managing software solutions so that they can be scaled easily. This set of practices is technology agnostic, which means that there is not one single programming language or technology to build microservices. In fact, you can build microservices with any programming language. It's more about applying a certain number of architectural patterns and principles to your program.
