AWS Certified Advanced Networking – Specialty (ANS-C01)Network DesignMedium
A media company needs to provide low-latency access to its content for users across North America, Europe, and Asia. They have deployed their application and content in multiple AWS Regions. The company wants to use a global load balancing solution that routes users to the nearest available Region, considering the actual network latency from the user to the AWS edge. Which AWS service should they choose?
- AAWS Global Accelerator
- BApplication Load Balancer (ALB) in each Region
- CAmazon CloudFront with origin failover
- DAmazon Route 53 with simple routing policy
Show answer & explanationAnswer & explanation
Correct answer: A. AWS Global Accelerator
AWS Global Accelerator uses the AWS global network to route user traffic to the nearest healthy endpoint, reducing latency by bypassing congested internet paths. It provides two static Anycast IP addresses as a fixed entry point, directing traffic to the optimal AWS Region based on actual network conditions, not just DNS resolution.
Why the other options are wrong
- B. ALBs are regional load balancers; they don't provide global routing to the nearest region based on network latency.
- C. CloudFront caches content at edge locations and can route to origins, but Global Accelerator specifically optimizes performance for dynamic application traffic via the AWS backbone.
- D. Route 53 simple routing does not consider latency or endpoint health; it's a basic DNS record type.
AWS Global Accelerator
A networking service that improves the availability and performance of your applications with local and global users by routing traffic through the AWS global network infrastructure.
- Uses Anycast IP addresses as fixed entry points
- Routes traffic over the AWS global network
- Reduces internet latency and jitter
- Provides automatic failover to the nearest healthy endpoint
Memory trick: Global Accelerator makes users feel closer, faster.
