Global latency with AWS CloudFront and AWS AppSync

[shubhamNagarro2502]

ISSUE - Global latency with AWS Cloudfront and AWS AppSync whereas AWS Gatway (edge optimized) with AWS AppSync showing better results (low latency)

I tried multiple POC with AWS AppSync.

POC 1 - High TTFB with ASIA region without AWS Cloudfront Detail - AWS AppSync deployed in us-east-1 region Screenshot -

POC 2 - High TTFB with ASIA region with AWS CloudFront Detail - AWS AppSync deployed in us-east-1 region, used AWS CloudFront to solve global distribution/persistent connection for faster connections and data compression Result - 10% improvement in latency but no data-compression got Screenshot -

POC 3 - Low TTFB in ASIA region with AWS Gatway (edge optimized) with AWS AppSync Detail - AWS Gateway deployed in us-east-1 region with edge-optimized which internally uses AWS CloudFront for persistent connection Result - 30% improvement in latency with data compression
