A global e-commerce platform relies on Azure Kubernetes Service (AKS) clusters deployed in multiple regions to serve its customers. The platform needs to ensure that if an entire Azure region becomes unavailable, traffic is automatically redirected to the nearest healthy region. Which Azure service should be used to achieve this global traffic redirection and high availability for the AKS clusters?
- AAzure DNS
- BAzure Load Balancer
- CAzure Application Gateway
- DAzure Front Door
Show answer & explanationAnswer & explanation
Correct answer: D. 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, automatic failover across regions, and path-based routing.
Why the other options are wrong
- A. Azure DNS provides domain name resolution but does not actively manage traffic redirection or health probing for automatic failover.
- B. Azure Load Balancer is a regional layer 4 load balancer, not designed for global traffic management or advanced routing across regions.
- C. Azure Application Gateway is a regional layer 7 load balancer, not designed for global traffic management across regions.
