Microservices
Build scalable systems with independently deployable services
What is Microservices?
Microservices architecture structures an application as a collection of loosely coupled, independently deployable services. Each service is organized around a specific business capability and can be developed, deployed, and scaled independently. Services communicate via well-defined APIs, typically over HTTP/REST or message queues. Microservices architectures often combine patterns like Event Driven Architecture and CQRS for scalability.

Key Components of Microservices Architecture
| Component | Description |
|---|---|
| API Gateway | Single entry point for client requests |
| Service Registry | Service discovery between services |
| Message Broker | Async communication (RabbitMQ/Kafka) |
| Config Server | Centralized configuration |
| Observability | Monitoring, tracing, logging |
When to Use It
- Large teams working on different parts of the system
- Need for independent deployment and scaling of components
- Different technology stacks for different capabilities
- High availability and fault isolation requirements
- Rapid iteration and continuous delivery

Benefits
- Independent scaling of services
- Technology flexibility per service
- Fault isolation—one service failure doesn't cascade
- Team autonomy and parallel development
- Faster feature delivery
- Better system resilience
Challenges
- Distributed system complexity
- Data consistency across services
- Operational overhead (monitoring, deployment)
- Network latency and reliability
- Testing across services
- Service versioning
Real World Example
E-commerce Order Processing
An e-commerce platform splits order management, inventory, payments, and notifications into separate microservices. Each can scale independently during peak sales, and a payment service outage doesn't block order creation. Peak traffic handled with independent service scaling.
Services
- Order Service
- Payment Service
- Inventory Service
- Notification Service
Communication
- REST APIs for synchronous calls
- RabbitMQ events for asynchronous workflows
