Cloud Architecture Patterns

This guide covers common cloud architecture patterns and best practices for implementing them in your applications.

Microservices Architecture

Key Components

  • API Gateway: Single entry point for all client requests
  • Microservices: Independent services with specific business capabilities
  • Databases: Dedicated databases for each service

Event-Driven Architecture

Benefits

  • Loose coupling between components
  • Better scalability and resilience
  • Asynchronous processing capabilities

Serverless Architecture

Use Cases

  • Event processing
  • Real-time file processing
  • API backends
  • Scheduled tasks

Best Practices

  1. Security First

    • Implement authentication and authorization
    • Use encryption in transit and at rest
    • Regular security audits

  2. Scalability

    • Design for horizontal scaling
    • Use caching effectively
    • Implement load balancing

  3. Reliability

    • Implement circuit breakers
    • Use health checks
    • Plan for disaster recovery

  4. Monitoring

    • Set up comprehensive logging
    • Implement metrics collection
    • Use distributed tracing
