AWS学习笔记（十五）：CloudFront

CloudFront vs S3 Cross Region Replication

CloudFront:

• Global Edge network
• Files are cached for a TTL (maybe a day)
• Great for static content that must be available everywhere

S3 Cross Region Replication:

• Must be setup for each region you want replication to happen
• Files are updated in near real-time
• Read only
• Great for dynamic content that needs to be available at low-latency in few regions

CloudFront Signed URL vs S3 Pre-Signed URL

CloudFront Signed URL:

• Allow access to a path, no matter the origin
• Account wide key-pair, only the root can manage it
• Can filter by IP, path, date, expiration
• Can leverage caching features
  S3 Pre-Signed URL:
• Issue a request as the person who pre-signed the URL
• Uses the IAM key of the signing IAM principal
• Limited lifetime
