Clear Definition

Monolith: Single deployable unit containing all functionality. Microservices: Architecture with multiple independent, deployable services. Choose based on team size, complexity, and scale requirements.

šŸ’” Key Insight: Start with monolith, evolve to microservices when needed. Don't microservices prematurely.


Core Concepts

Monolith Advantages

  • Simple deployment
  • Easier development
  • Lower operational overhead
  • Better for small teams

Microservices Advantages

  • Independent scaling
  • Technology diversity
  • Team autonomy
  • Fault isolation

Best Practices

  1. Start Monolith: Begin simple, evolve when needed
  2. Identify Boundaries: Domain-driven design
  3. API Gateway: Single entry point
  4. Service Mesh: Handle inter-service communication

Quick Reference Summary

Monolith: Single deployable unit. Start here for simplicity.

Microservices: Independent services. Use when scale/complexity demands it.

Key: Don't microservices prematurely. Start monolith, evolve.
