The benefit of decomposing an application into different smaller services are numerous:
- Modularity: This makes the application easier to understand, develop, test, and become more resilient to architecture erosion. This benefit is often argued in comparison to the complexity of monolithic architectures.
- Scalability: Since microservices are implemented and deployed independently of each other, i.e. they run within independent processes, they can be monitored and scaled independently.
- Integration of heterogeneous and egacy systems: microservices is considered as a viable mean for modernizing existing monolithic software application. There are experience reports of several companies who have successfully replaced (parts of) their existing software by microservices, or are in the process of doing so. The process for Software modernization of legacy applications is done using an incremental approach.
- Distributed development: it parallelizes development by enabling small autonomous teams to develop, deploy and scale their respective services independently. It also allows the architecture of an individual service to emerge through continuous refactoring. Microservice-based architectures facilitate continuous delivery and deployment.
