June 20 2018 Taipei Bob Yeh Cloudfront Technical Seminar https://github.com/awshktsa/AWSTPEWorkshop-20180620-CF-ALB-EC2/blob/master/README.md

Quick Points from the Seminar

• Static content acceleration - S3
• Dynamic content acceleration
• Header is very important
• Know the lifecycle of content (TTL + invalidation)
  • The expiration table: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html
• Optimization
  • First enable logging
  • Set all TTL=0, operate without acceleration
  • Check "popular objects"
• Operation
  • Operation error could result in stale content, or spike in backend (and maybe more cost)
• Work with WAF
  • Can block traffic from a country etc.
  • Constrain size
