The microservices architecture is a collection of small units (also addressed as containers) that together represent a finished application or solve a specific global task. Each microservice in the app is responsible for some specific functionality. The main advantage is that they can be independently deployed and tested, which brings more efficiency to the whole process of development as there is less downtime. Whereas with monoliths, it is almost impossible to do as it is a single-piece software.
Microservices can be located on different servers and operating systems and can be written in different programming languages. Many software development companies prefer to use Golang as it is suitable for microservices development. It’s a highly flexible language that works quickly and significantly cuts the time spent on compiling and testing new code.
