Key Concepts Overview​

Service Models​

  • IaaS: Control & flexibility (AWS EC2, Azure VMs)
  • PaaS: Developer-focused (Heroku, Google App Engine)
  • SaaS: Ready-to-use (Salesforce, Microsoft 365)
  • FaaS: Serverless (AWS Lambda, Cloud Functions)

Deployment Models​

  • Public: Shared infrastructure, lowest cost, most scalability
  • Private: Dedicated infrastructure, highest control, highest cost
  • Hybrid: Combine public and private, best of both
  • Community: Shared among organizations with common interests

Critical Concepts​

  • Elasticity: Automatic scaling based on demand
  • Availability: Multi-region and multi-AZ deployment
  • Cost: Right-sizing, reserved instances, managed services
  • Security: Shared responsibility model
