Answer from AI
The CDN (Content Delivery Network) service accelerates the distribution of static and dynamic web content (files like .html, .css, .js, images, videos) by caching it on a global network of edge locations. This reduces latency for end-users and decreases the load on origin servers.
Key features:
- Global network of Edge Locations: Located closer to end-users, ensuring fast content delivery.
- Support for various content types: Static (images, videos) and dynamic (data generated by the server).
- Integration with other AWS services: S3, EC2, Route 53, WAF.
- Security: Supports HTTPS, integrates with AWS WAF for web attack protection.
- Caching configuration: Flexible cache lifetime management (TTL).
- Invalidation: Ability to forcibly delete cached objects.
- Lambda@Edge: Executes Lambda code at Edge Locations to modify CDN behavior.
Use cases:
- Accelerating delivery of websites and web applications.
- Distributing media content (on-demand videos, streaming).
- Delivering software and updates.
- Protecting against DDoS attacks at the CDN level.
