AWS's global CDN that distributes content (web, streaming, APIs) from more than 400 points of presence (PoPs) worldwide. It reduces latency by serving content from the node closest to the user.
On CLF-C02 and SAA-C03 this is the solution for low global latency. It integrates natively with S3, ALB, and API Gateway. Question: how do you serve images from S3 with low latency globally? CloudFront + S3.
Amazon CloudFront is a concept that can show up on the exam. Check the full guide to see it in context.
