Transcript

  • 1. Amazon Web Services A quick introduction
  • 2. Part 1: The whistle-stop tour
  • 3. Cloud Computing
      • Computing resources provided "as a service"
        • Multiple concurrent customers
        • Per-usage billing
        • Scalable
      • Infrastructure (IaaS), application platforms (PaaS), software (SaaS)
  • 4. Amazon Web Services (AWS) Image adapted from Amazon Web Services
  • 5. AWS Characteristics
  • 6. On-demand provisioning
  • 7. Pay as you use
  • 8. Scalable
  • 9. Software Agnosticism
  • 10. Loose Coupling
  • 11. Geographical Spread
  • 12. Part 2: Use AWS to meet typical requirements
  • 13. Requirement: Scalability
      • Amazon EC2 with auto scaling:
        • Do not scale up unless you need it
        • Scale down if you don't any more
  • 14. Autoscaling
      • Scale up (and down) EC2 instances depending on demand
      • Combine with Elastic Load Balancing
  • 15. Requirement: Geographical Spread
      • Amazon EC2 regions and Availability Zones:
        • Multiple regions, independent Availability Zones per region
      • Amazon CloudFront Content Distribution Network (US, EU, Asia)
  • 16. Regions Multiple Availability Zones per region US East 4 AZs US West 2 AZs Ireland 2 AZs Singapore 2 AZs
  • 17. Requirement: Redundancy and Availability
      • Host across regions and availability zones
      • Replacement instances in a few minutes
  • 18. Availability Zones
      • Per-region
      • Architected independently
      • Low cost, low latency, inter-AZ comms
      • Run instances across AZs
      • Disaster recovery using AZs
  • 19. AWS Redundancy and Availability Elastic Block Storage (EBS)
      • Redundant within AZ
      • S3 Snapshots for across-AZ redundancy
      •   Annual Failure Rate: 0.1% - 0.5% 
        • (10 times as reliable as commodity disks)
    Simple Storage Service (S3)
      • Redundant across AZs
      • Replicate across regions
      • 99.999999999% durability, 99.99% availibility
    Elastic Cloud Compute (EC2)
      • 99.95% availability per region
        • Availability of at least 1 region/4 running:99.9999999999999%
      • Available across AZs
      • Can be migrated across regions
  • 20. AWS Security
