Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsEasy
A global media company is building a new content delivery platform that needs to distribute large video files and static assets to users worldwide with low latency and high availability. The solution must cache content close to end-users and offload traffic from origin servers. Which Azure service is BEST suited for this purpose?
- AAzure Storage Account (Blob Storage)
- BAzure Front Door
- CAzure Traffic Manager
- DAzure CDN (Content Delivery Network)
Show answer & explanationAnswer & explanation
Correct answer: D. Azure CDN (Content Delivery Network)
Azure CDN (Content Delivery Network) is specifically designed to deliver web content to users by caching it at strategically placed edge nodes around the world. This reduces latency, improves content delivery speed, and offloads traffic from origin servers, making it ideal for distributing large video files and static assets globally.
Why the other options are wrong
- A. Azure Storage Account (Blob Storage) is an origin store for content, but it does not provide global caching and edge delivery capabilities on its own.
- 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 has CDN capabilities, CDN is more explicitly focused on content caching and delivery.
- C. Azure Traffic Manager is a DNS-based traffic load balancer that distributes user traffic to different service endpoints based on various routing methods, but it does not cache content.
Azure Content Delivery Network (CDN)
A distributed network of servers that delivers web content and streaming media to users based on their geographic location.
- Caches content at edge locations
- Reduces latency and improves load times
- Offloads traffic from origin servers
