What is the microservice architecture?
We all know that microservice architecture is an architectural concept that aims to decouple solutions by decomposing functions into discrete services. You can think of it as being at the architectural level rather than getting services
Many SOLID principles are applied to the class. Microservice architecture is an interesting concept. Its main function is to decompose functions into discrete services, thereby reducing the coupling of the system and providing more flexible service support.
concept:
Split a large single application and service into several or even dozens of supporting microservices, which can extend a single component instead of the entire application stack to meet service level agreements.
definition:
Create applications around business domain components that can be developed, managed, and iterated independently. The use of cloud architecture and desktop deployment, management and service functions in distributed components makes product delivery easier.
Nature
Use some services with clearer functions and more refined business to solve larger and more practical problems.
How important is the change in the thinking of microservice architecture?
What microservices think about us is more of a change in thinking. For the microservice architecture: technology is not a problem, awareness is more important than tools.
Some design starting points about microservices :
1. The core of the application is business logic, which organizes resources according to business or customer needs (this is the most difficult)
2. Make a living product, not a project
3. First wolf team, full stack
4. The background service implements the Single Responsibility Principle (single responsibility principle)
5、VM->Docker （to PE）
6 、 DevOps (to PE)
At the same time, for development students, it is a good thing to have so many middleware and strong PE support. We also need to deeply understand the principles behind these middlewares, know what they are, and how to use open source technology with limited technical resources. Implement microservices?
Finally, it is generally mentioned that microservices are inseparable from DevOps and Docker. Understanding the microservice architecture is the core, and devops and docker are tools and means.
Let's use two documents to understand the microservice architecture and its design patterns. If you have any unique insights on the microservice architecture, please leave a message in the comment area.
