What Is Amazon AWS CloudFront

Are you gearing up for your AWS Solutions Architect exam? Or just looking to speed up your global application? In this deep dive, we break down everything you need to know about Amazon CloudFront, AWS’s massive Content Delivery Network (CDN).

We’ll take you from the absolute basics of reducing latency to advanced concepts like edge computing and security best practices. Learn how to architecture for performance, handle cache misses effectively, and choose the right compute options for your needs.

In this video, we cover:

The Fundamentals: Understanding CDNs and how they solve the "speed of light" problem for global users.

Core Components: Origins, Edge Locations (Points of Presence), and Distributions.

The Request Journey: Step-by-step tracing of a user request, including DNS routing, Cache Hits, and Cache Misses.

Security & Performance: How to lock down S3 buckets with Origin Access Control (OAC), use AWS WAF, and handle high availability with Origin Groups.

Edge Computing: The critical exam difference between CloudFront Functions and Lambda@Edge.

The Ecosystem: When to use CloudFront vs. AWS Global Accelerator.
