Key Takeaways
- ā¢CloudFront is a CDN with 400+ edge locations that caches content close to users for faster delivery
- ā¢Origins can be S3 buckets, ALB/NLB, EC2 instances, or any custom HTTP backend
- ā¢TTL controls cache duration; invalidations force immediate cache refresh bypassing TTL
- ā¢Global Accelerator uses 2 static Anycast IPs routing traffic through AWS network for low latency
- ā¢CloudFront serves cached HTTP/S content; Global Accelerator proxies TCP/UDP for non-cacheable traffic
