Introduction Spring AOP (Aspect Oriented Programming) compliments OOPs as it also provides modularity. But The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect. AOP breaks the program logic into distinct parts (called concerns). It is used to increase modularity by cross-cutting concerns such as transaction management, […]

41. What is the role of web and RESTful APIs in Microservices?A microservice architecture is based on a concept wherein all its services should be able to interact with each other to build a business functionality. So, to achieve this, each microservice must have an interface. This makes the web API a very important enabler
31.

In a distributed system involving multiple databases, we have two options to achieve ACID compliance: 2 Phase Commit should ideally be discouraged in microservices architecture due to its
11. How can we test the Microservices based architecture?One should have unit and integration tests where all the functionality of a microservice can be tested. One should also have component based testing.One should have contract tests to assert that the expectations by the client is not breaking. End-to-end test for the microservices, however, should only
1.
