The document discusses five key principles for architecting applications on AWS: elasticity, designing for failure, loose coupling, security, and performance. It provides examples and services for each principle such as using Amazon EC2 for elasticity, designing with fault tolerance using services like RDS and Route 53, loosely coupling components with services like SQS and SWF, leveraging security services like IAM, and scaling vertically with cluster compute or horizontally using services like ElastiCache for performance.

- 21. # 2 DESIGN FOR FAILURE ●●○○○
- 22. « Everything fails all the time » Werner Vogels CTO of Amazon
- 23. YOUR GOAL Applications should continue to function even if the underlying physical hardware fails or is removed or replaced
- 24. Avoid single points of failure. Assume everything fails, and design backwards.
