Microservices Architecture Simulator - Learn Service Communication & Resilience
Understanding Microservices Architecture
What You'll Learn
- Microservices vs monolithic architecture patterns
- Service-to-service communication (sync vs async)
- Independent scaling of services
- Failure handling and resilience patterns
- Service discovery and API gateways
- Distributed system challenges
Key Benefits
✓ Independent Deployment: Deploy services separately
✓ Technology Diversity: Use best tools per service
✓ Fault Isolation: Failures don't cascade
✓ Independent Scaling: Scale services based on demand
✅ When to Use Microservices
- • Large, complex applications
- • Large development teams (50+ people)
- • Rapidly changing requirements
- • Need independent deployments
- • Different scaling needs per component
❌ When to Avoid
- • Small applications
- • Small teams (<10 people)
- • Simple CRUD applications
- • Tight coupling between features
- • Network latency is critical
💡 Pro Tips
- • Start with a monolith and decompose when needed
- • Use API gateways for centralized routing and auth
- • Implement circuit breakers to prevent cascade failures
- • Monitor distributed traces across all services
- • Use message queues for async communication
- • Each service should have its own database
Real-World Examples
Netflix: 500+ microservices handling billions of requests
Amazon: Decomposed monolith to microservices in early 2000s
Uber: Moved from monolith to 2000+ microservices
