Microservice is getting widely used in day to day application building. Clear cut understanding of the concept it needed.
There are 9 attributes of Microservices. You need to evaluate each of them. And then which one applies for your project.
- Componentization via Services: Microservices are structured as independent components or services, each responsible for a specific business function. This modular approach enables flexibility, scalability, and ease of maintenance, as each service can be developed, deployed, and scaled independently.
- Organized Around Business Capabilities: Microservices are aligned with business capabilities or domains, ensuring that each service corresponds to a specific business function. This organizational principle promotes agility and focuses development efforts on delivering value to the business.
- Products, Not Projects: Microservices are treated as long-term products with ongoing ownership and responsibility. This approach encourages teams to prioritize quality, reliability, and maintainability, fostering a culture of continuous improvement and customer-centricity.
- Smart Endpoints and Dumb Pipes: Microservices communicate via lightweight protocols, such as HTTP or messaging queues, with minimal reliance on complex middleware. This design philosophy emphasizes self-contained services that are easy to understand, test, and evolve.
- Decentralized Data Management: Each microservice has its own database or data store, allowing teams to choose the most suitable solution for their service's requirements. This decentralized approach minimizes dependencies and supports autonomy, enabling teams to innovate and iterate independently.
- Infrastructure Automation: Microservices rely on automation for deployment, scaling, monitoring, and recovery, enabling rapid and reliable delivery of software at scale. Continuous integration/continuous deployment (CI/CD) pipelines, containerization, and orchestration tools streamline operations and enhance efficiency.
- Design for Failure: Microservices are designed to handle failures gracefully, with mechanisms such as redundancy, circuit breakers, and graceful degradation. This resilience-focused approach ensures that the system remains responsive and available, even in the face of unexpected failures or disruptions.
- Evolutionary Design: Microservices prioritize evolutionary design and incremental improvement over upfront planning and monolithic architectures. Services evolve iteratively based on feedback, changing requirements, and emerging business needs, enabling organizations to adapt quickly to market dynamics.
- Decentralized Governance: Decision-making authority and control are distributed across autonomous teams, empowering them to make decisions independently within the boundaries of their respective services. This decentralized approach fosters agility, innovation, and accountability, enabling teams to respond effectively to local requirements and business needs.
