What Are Microservices?
Microservices is an architectural style that structures an application as a collection of small, autonomous services. Each service implements a specific function and communicates with lightweight APIs.
Unlike monolithic architectures, microservices allow teams to develop and deploy individual components independently, fostering faster innovation and improved scalability.

Decentralized Data
Each service owns its database. This prevents tight coupling between components and allows teams to choose the best database for their needs.
Automated Deployments
CI/CD pipelines enable frequent, reliable updates to microservices without system-wide disruptions.
Resilient Communication
Services use REST/GraphQL or message queues for communication, with built-in timeouts and retries to handle failures.

Each service operates independently. The API Gateway handles authentication, request routing, and rate limiting.
Best Practices
Service Decomposition
- Organize services around business capabilities
- Use bounded contexts in domain modeling
- Ensure loose coupling between components
Monitoring & Security
- Implement distributed tracing
- Enforce mutual TLS
- Use service meshes for policy enforcement
- Monitor health with circuit breakers
