CloudFront vs S3 Cross Region Replication
CloudFront:¶
- Great for static content that must be available everywhere.
- Global Edge network.
- Files are cached for a TTL (maybe a day).
S3 Cross Region Replication¶
- Great for dynamic content that must be available at low-latency in a few regions.
- Replicate buckets into other regions.
- Read only.
- Must be setup for each Region.
- Files are updated in near real-time.
