🌟 What is Amazon CloudFront?
Amazon CloudFront is a Content Delivery Network (CDN) service from AWS that accelerates the delivery of your websites, APIs, videos, and other web assets to users worldwide. It does this by caching your content at over 700+ edge locations globally, so user requests are served from the nearest location with the lowest latency. This means faster load times, better performance, and improved user experience. 🌍⚡
CloudFront supports both static content (like images, CSS, JavaScript) and dynamic content (API responses, live streaming), making it versatile for many use cases.
🔍 How Does CloudFront Work?
When a user requests your content, CloudFront routes the request to the closest edge location. If the content is cached there, it delivers it immediately. If not, CloudFront fetches it from your origin (e.g., Amazon S3, EC2, or any HTTP server), caches it at the edge, and serves it to the user.
This reduces the distance data travels across the internet, lowers latency, and offloads traffic from your origin servers.
💡 Key Features & Benefits

- Customizable: Use Lambda@Edge to run serverless code at edge locations for content customization, authentication, or header manipulation.
- Media Streaming: Supports live and on-demand video streaming in multiple formats.
- Access Control: Origin Access Identity (OAI) restricts S3 bucket access only to CloudFront.
- Cost-Efficient: Reduces load on origin servers and optimizes bandwidth usage with caching and compression.
- Real-Time Metrics & Logging: Monitor traffic, performance, and troubleshoot with detailed analytics.
