Transcript

  • 1. Building Fault-TolerantApplications in the CloudRyan HollandEcosystem Solution Architect
  • 2. Faults?FacilitiesHardwareNetworkingCodePeople
  • 3. What is “Fault-Tolerant”?Degrees of risk mitigation - not binaryAutomatedTested!
  • 4. AgendaThe AWS ApproachBuilding BlocksDesign Patterns
  • 5. Old School Fault-Tolerance: Build Two
  • 6. Cloud Computing Benefits No Up-Front Low Cost Pay Only for Capital Expense What You Use Self-Service Easily Scale Improve Agility & Infrastructure Up and Down Time-to-Market Deploy
  • 7. Cloud Computing Fault-Tolerance Benefits No Up-Front HA Low Cost Pay for DR Only Capital Expense Backups When You Use it Self-Service Easily Deliver Fault- Improve Agility & DR Infrastructure Tolerant Applications Time-to-Recovery Deploy
  • 8. AWS Cloud allows Overcast Redundancy Have the shadow duplicate of your infrastructure ready to go when you need it……but only pay for whatyou actually use
  • 9. Old Barriers to HAare now SurmountableCostComplexityExpertise
  • 10. AWS Building Blocks: Two Strategies Inherently fault- Services that are fault-toleranttolerant services with the right architecture S3 Amazon EC2 SimpleDb VPC DynamoDB Cloudfront EBSSWF, SQS, SNS, SES RDS Route53Elastic Load Balancer Elastic Beanstalk ElastiCache Elastic MapReduce IAM
  • 11. Resources DeploymentThe Stack: Management Configuration Networking Facilities Geographies
  • 12. EC2 Instances Amazon Machine ImagesThe Stack: CW Alarms - AutoScaling Cloudformation - Beanstalk Route53 – ElasticIP – ELB Availability Zones Regions
  • 13. Regional DiversityUse Regions for: Latency • Customers • Data Vendors • Staff Compliance Disaster Recovery … and Fault Tolerance!
  • 14. Proper Use of Multiple Availability Zones
  • 15. Network Fault-Tolerance Tools107.22.18.45 isn’t fault-tolerant but 50.17.200.146 is: EIPElastic Load BalancingAutomated DNS: Route53Latency-Based Routing
  • 16. New EC2 VPC feature:Elastic Network Interface Up to 8 Interfaces with 30 Addresses each Span Subnets Attach/Detach Public or Private
  • 17. Cloudformation – Elastic Beanstalk Q: Is your stack unique?
  • 18. Cloudwatch – Alarms – AutoScaling
  • 19. AMI’sMaintenance is criticalAlternatives: Chef, Puppet, cfn-init, etc.When in doubt: 64-bitReplicate for DR
  • 20. EC2 InstancesConsistent, reliable building block100% API controlledReserved InstancesEBSImmense Fleet Scale
  • 21. Example:a “fork-lifted” app
  • 22. Example:Fault-Tolerant
  • 23. Why mess with all of that?
  • 24. Design For FailureSPOF
