Скачать или смотреть What Is Amazon CloudFront Distribution

Preparing for the AWS Certified Solutions Architect exam? Or just trying to understand how to speed up your global application? In this video, we break down Amazon CloudFront to give you a crystal-clear mental model of how this massive service works.

We start with the "Global Speed Problem" (latency) and trace the exact journey of a user request to explain the difference between a Cache Hit and a Cache Miss. Then, we pop the hood to look at the anatomy of a Distribution, including Origins, Behaviors, and critical security settings like OAI and Signed Cookies. Finally, we cover the key architectural decisions you need to make to build resilient, high-performance apps on AWS.

🚀 In this video, you will learn:

Why latency kills performance and how Edge Locations solve it.

The exact 6-step lifecycle of a CloudFront request.

How to secure S3 buckets using Origin Access Identity (OAI).

The difference between Signed URLs and Signed Cookies.

How to optimize performance using Cache Keys and TTL.

How to handle Origin Failover for high availability.
