Getting Started

• Basics - Course Supplement
• What is AWS?
  • AWS is a company - Amazon Web Services, a subsidiary of Amazon (amazon.com)
  • It is a Cloud Computing Services Provider
• Cloud Computing
  • cloud architecture terms
• AWS Infrastructure (Regions, AZs, Edge locations)
  • AWS Ground Station
• Cloud Computing Responsibility
• Disaster recovery
  • CloudEndure Disaster Recovery
  • Business Continuity Plan (BCP)
• Self Service & Managed Services
  • Two main kinds of services
    • You can mix & match different services as you need
  • Self Service
    • Do it yourself
    • EC2 - configure and launch a server → only the hardware is managed by AWS
  • Managed Services
    • AWS manages the hard parts.
    • Partially configurable
    • Can be used together with other services (self-service)
• Service categories
  • https://aws.amazon.com/ > products
    • some services do show up multiple times in different categories
    • some listed things aren’t actually services but features (lol)
  • Group
    • The groups solve different problems & do different workloads
