Why Microservices

Quick Reference: Monoliths vs Microservices | Containerization

Quick Reference

Benefits: Independent scaling, technology diversity, team autonomy, fault isolation

When to Use: Large teams, complex domains, need for independent scaling

Trade-offs: Increased complexity, network overhead, distributed system challenges

Clear Definition

Microservices enable independent development, deployment, and scaling of services. Use when monolith becomes bottleneck for team velocity or system scale.

šŸ’” Key Insight: Microservices solve organizational and scaling problems, not just technical ones.

Core Concepts

Benefits

  1. Independent Scaling: Scale services based on load
  2. Technology Diversity: Use best tool for each service
  3. Team Autonomy: Teams own services end-to-end
  4. Fault Isolation: Failure in one service doesn't bring down all

Challenges

  1. Complexity: More moving parts
  2. Network Overhead: Inter-service communication
  3. Data Consistency: Distributed transactions
  4. Operations: More services to monitor

Best Practices

  1. Domain-Driven Design: Identify service boundaries
  2. API Design: Well-defined service interfaces
  3. Observability: Comprehensive monitoring
  4. Automation: CI/CD for each service

Quick Reference Summary

Why Microservices: Independent scaling, team autonomy, technology diversity, fault isolation.

When: Large teams, complex domains, need for independent scaling.

Key: Solve organizational and scaling problems, not just technical.
