Microservices architecture structures an application as a collection of small, independent services that communicate over APIs. Each service handles a specific business function, can be developed and deployed independently, and can use different technologies. This contrasts with monolithic architecture where everything is in a single codebase.
Key Points
- Each service is independently deployable and scalable
- Services communicate via REST APIs, gRPC, or message queues
- Enables different teams to work on different services with different tech stacks
- Adds operational complexity — requires DevOps maturity (Docker, Kubernetes, monitoring)

Frequently Asked Questions
Start with a monolith for new projects — it's simpler and faster to build. Consider microservices when: your monolith becomes too large for one team, you need independent scaling of specific features, or you need different tech stacks for different components. Most Indian startups should start monolithic and migrate to microservices as they scale.
Key challenges: distributed system complexity (network failures, data consistency), operational overhead (monitoring many services), debugging across service boundaries, and data management (each service may need its own database). You need strong DevOps practices before adopting microservices.
