Which AWS service is best suited for content delivery and edge caching?

Amazon CloudFront is the best-suited service for content delivery and edge caching for several reasons. As a specialized Content Delivery Network (CDN), CloudFront is designed to distribute content globally with low latency. It achieves this by caching copies of content in multiple edge locations around the world. When a user requests content, CloudFront serves it from the nearest edge location, which speeds up the delivery of static and dynamic web content like HTML pages, images, and videos.

The service offers optimized performance due to its globally distributed network, allowing for quick access to data while also reducing the load on origin servers. Additionally, CloudFront seamlessly integrates with other AWS services, such as Amazon S3 for storing original content and AWS Lambda for dynamic content generation, making it a versatile choice for enhancing web application performance.

In contrast, AWS Lambda is primarily a serverless computing service that allows you to run code in response to events, but it does not provide content delivery or caching capabilities. Amazon S3 is an object storage service used for storing and retrieving data but lacks the distribution and caching functionalities that CloudFront specifically offers. Lastly, Amazon Glacier is focused on long-term data archiving and is not designed for content delivery, caching, or performance optimization.
