Microservice is an architectural style that made up of smaller (micro) applications that communicate with each other, through open protocols like HTTP. Microservices have a much simpler and direct communication mechanism. Microservices typically deployed Docker platforms in the cloud environment will get maximum benefit.
Microservices architecture’s main aim is to break down the applications into smaller applications for maintainability and address the particular functionality. Microservices are scalable, and the maintainability of the application was as typical in monolithic applications. Below are some of the benefits of microservices architecture
- Time to market for new functionality
- Seamless integrations
- Adoption of new technologies
- Resource (Hardware) utilization effectively
- Security
- API based functions for reuse effectively
In monolithic apps, all the functionalities are part of a single application and deployed as a single war/ear file. Earlier days, most of the applications are building by using the MVC design pattern. Microservice architectures create applications that remain maintainable in the long run since the applications are can modify and deploy without impacting other services leads to flexibility. Development and deployment efforts are increasing, and testing should perform for each component or Service in Microservice applications
The biggest challenge is deciding how to partition the exiting system into Microservices. Some strategies have to adapt to decouple the Microservices from existing Monolithic applications. Below are some of the patterns uses in the different domains while decoupling the applications. The patterns are widely used in all domains
- Decompose by Business Capability
- Decompose by Sub Domain
- API Gateway
- Aggregator
- Circuit Breaker
- Distribute Tracing
- Log Aggregator
