Microservices and SOA The difference between

One 、 Differences and connections ？

After the service-oriented transformation of the business system , The originally shared business is split into sharable services , The repeated construction of shared services can be avoided to the greatest extent , Resource connection bottleneck , Whether the split services also need to be split and deployed in the dimension of business functions , To reduce business coupling and improve fault tolerance ？
Microservices are such a solution , From the name , Service oriented （SOA） And microservices are essentially an embodiment of the idea of service , If SOA It is the rudiment of service-oriented development , So microservice is a further optimization for reusable business services , We can SOA As a superset of microservices , Once the service scale is expanded, it means the construction of services 、 Release 、 The complexity of operation and maintenance will also increase exponentially , Therefore, the premise of implementing microservices is the maturity of software delivery links and infrastructure , Therefore, microservice is not a new concept in my opinion , In essence, it is the best practice direction of service-oriented thinking , because SOA And microservices have different concerns , This makes a big difference between the two .

• SOA It focuses on the reusability of services and solving the problem of information island .
• Microservices focus on decoupling , Although decoupling and reusability are the same from a certain point of view , But in essence, it is differentiated by , Decoupling is to reduce the coupling between services , Reusability focuses on the reuse of services
• Microservices will pay more attention to DevOps Continuous delivery of , Because after the service granularity is more refined , Make development, operation and maintenance more important , Therefore, the combination of microservices and container technology is closer
