How does the microservice architecture work?

Until now, we have discussed various things about the microservice architecture, and we can now depict how the microservice architecture works; we can use any combination as per our design approach or bet on a pattern that would fit in it. Here are a few points that favor the working of the microservice architecture:

• It's programming of the modern era, where we are expected to follow all SOLID principles. It's object-oriented programming (OOP).
• It is the best way is to expose the functionality to other or external components in a way so that any other programming language will be able to use the functionality without adhering to any specific user interfaces, that is, services (web services, APIs, rest services, and so on).
• The whole system works as per 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.
