Can you serve images directly from S3 static website hosting? You’ll avoid any cold start (and Lambda costs) that way. You could also put CloudFront or Cloudflare in front for caching after the first request.
1. Use proper cloudfront caching. I see that all images are hitting the origin every time. Its adding more latency to the request.
2. Set proper cache headers.
3. Fix www.figmage.com. Don't put https in DNS. LOL
4. Enable IPv6 in cloudfront.
