💡

Main point: Use Application Load Balancer (ALB) with CloudFront over using ALB alone

Reduced Latency

CloudFront delivers content from edge locations closer to users and utilizes the AWS backbone network from the edge to the ALB.

ALB without CloudFront: load time =~ 750ms

ALB with CloudFront: load time =~ 440ms

CloudFront supports TLS 1.3

CloudFront maintains persistent connections to the ALB, which minimizes the overhead of establishing new TCP connections for each request.

ALB without CloudFront

ALB with CloudFront reduces initial connection: 278.8ms -> 17.5ms
