Microsoft Azure Fundamentals (AZ-900)Describe Azure identity, security, and networkingMedium
A company is deploying a new web application in Azure. They need to ensure that the application is resilient to regional outages and provides low-latency access to users located across different geographic locations. Which Azure service should they use?
- AAzure Front Door
- BAzure Traffic Manager
- CAzure Application Gateway
- DAzure Load Balancer
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Front Door
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. It provides global load balancing, site acceleration, and enhanced security features, making applications resilient to regional outages and offering low latency to globally distributed users.
Why the other options are wrong
- B. Azure Traffic Manager is a DNS-based traffic load balancer that distributes traffic at the DNS level, but Azure Front Door offers more advanced features like WAF, SSL offloading, and HTTP/S optimization at the application layer globally.
- C. Azure Application Gateway is a regional load balancer and web application firewall, not designed for global distribution and low latency across regions.
- D. Azure Load Balancer operates at the transport layer (Layer 4) within a single Azure region and does not provide global traffic distribution or application-layer features.
Azure Front Door
A global, scalable entry point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications.
- Global load balancing for optimal routing
- Application-layer security (WAF)
- SSL offloading and end-to-end SSL
- Site acceleration using Microsoft's global network
Memory trick: Front Door opens globally with speed and security.
