As the name suggests, microservices are basically independent software services that provide a specific feature or function in a software application and serve a single purpose. These services should be independently maintainable, traceable and deployable.
Microservices are modular projects that have a single responsibility and do a single job and only carry out the works of that job.
What are the Advantages of Microservice Architecture?
Independent Deployment — Services can be deployed independently on any platform.
Independent Development — The entire microservice can be easily developed according to its own functionality.
Fault Isolation — Since a problem that may occur in any service of the project will not affect other services of the project, the system still continues to work.
Scalable — Each component can be scaled to its own needs, no need to scale all components.
Technology Diversity — Different languages and technologies can be used when developing different services for the same project.
Key features of Microservices:
Decoupling — Services in a system are largely independent of each other.
Componentization — Microservices are self-contained components that can be easily modified and upgraded.
Business Capabilities — A microservice is simple in structure and focuses on a single task.
Autonomy — Developers and teams can work independently, enabling rapid development and testing.
Continuous Delivery — Automatically allows for frequent software releases to go live with systematic automation of software development, testing, and validation. As services can be deployed individually, deployment time is shortened and cost is reduced over time.
Decentralized Governance — The focus is on using the right tool for the right job. This means that it does not enforce a standard technology or structure. Developers have the freedom to choose the best technology to solve their problems.
Agility — Microservices support agility. Any new feature can be rapidly developed and adapted to the system.
