What Are Microservices?
Microservices architecture structures applications as a collection of loosely coupled, independently deployable services.
Key Characteristics
- Single responsibility
- Independent deployment
- Decentralized data management
- Failure isolation
- Technology diversity
When to Use Microservices
Good Fit
- Large, complex applications
- Multiple development teams
- Need for independent scaling
- Polyglot requirements
When to Avoid
- Small applications
- Small teams
- Simple domains
- Rapid prototyping
Design Patterns
API Gateway
Single entry point for all clients.
Service Discovery
Dynamic service location.
Circuit Breaker
Fault tolerance and resilience.
Event Sourcing
Event-driven communication.
Conclusion
Microservices enable scalability and agility but require careful design and operational maturity.
