We have gone through a few definitions of microservices; now let's discuss them in detail.
In short, a microservice architecture removes most of the drawbacks of SOA. It is also more code-oriented than SOA services (we will discuss this in detail in the coming sections).
Before we move on to understanding the architecture, let's discuss the two important architectures that led to its existence:
- The monolithic architecture style
- SOA
Most of us know that when we develop an enterprise application, we have to select a suitable architectural style. Then, at various stages, the initial pattern is further improved and adapted with changes that cater to various challenges, such as deployment complexity, a large code base, and scalability issues. This is exactly how the monolithic architecture style evolved into SOA, and then led to microservices.
