A global media company is building a new content delivery platform that needs to distribute large video files and images globally with extremely low latency. The platform must cache static and dynamic content at edge locations worldwide to improve user experience and reduce origin server load. Which Azure service is BEST suited for this content delivery requirement?
- AAzure Content Delivery Network (CDN)
- BAzure Front Door
- CAzure Application Gateway
- DAzure Traffic Manager
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Content Delivery Network (CDN)
Azure Content Delivery Network (CDN) is specifically designed to deliver web content to users with high bandwidth and low latency by caching content at strategically placed physical nodes (Points of Presence) around the world. It is ideal for distributing large static and dynamic files like videos and images globally.
Why the other options are wrong
- B. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications. While it includes CDN capabilities, the primary need for 'distribute large video files and images globally with extremely low latency' and 'cache static and dynamic content at edge locations' points more directly to the core function of a CDN.
- C. Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. It operates at Layer 7 and is typically deployed per region, not for global edge caching.
- D. Azure Traffic Manager is a DNS-based traffic load balancer that distributes incoming traffic across global Azure regions or external endpoints. It does not cache content at edge locations.
Azure Content Delivery Network (CDN)
A global content delivery solution for delivering high-bandwidth content to users by caching it at strategically placed edge nodes.
- Caches static and dynamic content at Points of Presence (PoPs).
- Reduces latency and improves load times for end-users.
- Offloads traffic from origin servers.
Memory trick: CDN: 'Content' delivered 'Directly' and 'Now'here.
