The terms ‘Microservices’ and ‘Microservices Architecture’ refer to the same thing – the technique of developing a software application as a collection of loosely coupled services that can be developed, deployed, and maintained independently.
Microservices is a type of service-oriented architecture (SOA) where each of the services are fine-grained and, at the same time, responsible for a distinct task within the application. Each service communicates with other services through simple APIs, coming together to solve complex business problems.
