The following are the benefits of Microservices:
- Microservices architecture satisfies the need to respond to change quickly. The software market is really competitive nowadays. If your product can't provide a feature that's in demand, it will lose its market share very quickly.
- It fulfills the need for a business-domain-driven design. The architecture of an application needs to match the organization structure, or the structure of the business functions within the organization.
- The Microservices architecture makes use of automated test tools. We've already seen that in a Microservices architecture, transactions are distributed, and therefore, a transaction will be processed by several services before it's complete. The integration between those services needs to be tested, and testing these Microservices together manually might be quite a complex task. Automated test tools help us to perform this integration testing, reducing the manual burden.
- Cloud-compliant Microservices can reduce the burden of deployment and release management.
- The Microservices architecture provides a platform to adopt new technology. Because the systems are made of several moving parts, we can easily change one part, that is, a Microservice from one technology stack to another technology stack in order to get a competitive edge.
- By using asynchronous communication, the distributed transaction does not have to wait for individual services to complete their tasks before it's complete.
- Microservices have shorter development times. Because the system is split up into smaller moving parts, we can work on a moving part individually, can have teams working on different parts concurrently, and because Microservices are small in size and they have a single focus, the teams have less to worry about in terms of scope.
- The Microservices architecture also offers us increased uptime, because when it comes to upgrading the system, we will probably deploy one Microservice at a time without affecting the rest of the system.
Netflix adopted the Microservices architecture; the lessons learnt on architectural designs are summarized in this link along with a video: https://www.nginx.com/blog/microservices-at-netflix-architectural-best-practices/.
