Microservice is a new Software Development methodology evolved in the last decade to support the vigorous usage of digital devices which works on multiple Software Development technology. Nowadays, Software is developed using Agile methodology, deployment over Containerization and Cloud using CI/CD, to support NoSQL databases, streamlined to a modern browser or smartphone and the devices are connected via a high-speed network. To meet out these challenges, Microservices Architecture emerged out 10 years back.
Monolith Architecture is the right approach for the applications that are lean in the long term and for application which is large and complex or has the potential to become large and complex, Microservice Architecture is the right solution. Modern Software development supports both Microservice Architecture and Monolith Architecture.
Microservices Best Practices
- Single Responsibility principle – Building single component to respond to single API fetch
- Separate Datastores approach- Exclusive Database for each microservice share
- Use Asynchronous Communication to achieve loose coupling – Dependencies can be called out asynchronously and using events for communicating between Microservices
- Fail fast by using a circuit breaker to achieve fault tolerance- Fail fast by using a circuit breaker to achieve fault tolerance
- Proxy your microservice requests through an API Gateway
- API changes are to be backwards compatible
- Provisioning of versions to Microservices
- Infrastructure hosting should be dedicated to each Microservice
- Separate release approach to each and every component
- Customize Microservices according to Enterprise’s business model
Advantages of Microservice Architecture
- Application scaling
- Improvised Development speed
- Autonomous Development scaling
- Independently deployable and release cycle happens with CI/CD techniques
- Loosely coupled highly cohesive Modularization designs of Microservice restricts the cross functional interfaces
- Easy replacement of single microservice with other gives the Modernization wherein increments happens one by one.
