Microservice architecture is an architectural style that structures an application as a collection of loosely coupled services. These services can intercommunicate or be independent of each other. The overall working architecture of a microservice-based application depends on the various patterns that are used to develop the application. For example, microservices could be based on backend or frontend patterns. We will discuss various patterns in Chapter 10, Design Patterns and Best Practices.
Up until this point, we have discussed various aspects of microservice architecture, and we can now depict how it works; we can use any combination according to our design approach or predict a pattern that would fit. Here are some benefits of working with microservice architecture:
- In the current era of programming, everyone is expected to follow all of the SOLID principles. Almost all languages are object-oriented programming (OOP).
- It is the best way is to expose functionality to other, or external, components in a way that allows any other programming language to use that functionality without adhering to any specific user interfaces (that is, services such as web services, APIs, REST services, and so on).
- The whole system works according to a type of collaboration that is not interconnected or interdependent.
- Every component is liable for its own responsibilities. In other words, components are responsible for only one functionality.
- It segregates code with a separation concept, and segregated code is reusable.
