AWS Certified Advanced Networking – Specialty (ANS-C01)Network DesignMedium
A media company is streaming high-definition video content globally. They need to ensure users experience the lowest possible latency when accessing their content, regardless of their geographic location. The solution must intelligently route user requests to the nearest healthy application endpoint. Which AWS service is best suited for this requirement?
- AApplication Load Balancer (ALB)
- BRoute 53 Latency-based Routing
- CAmazon CloudFront
- DAWS Global Accelerator
Show answer & explanationAnswer & explanation
Correct answer: D. AWS Global Accelerator
AWS Global Accelerator uses the AWS global network to route traffic to the nearest healthy endpoint, bypassing congested public internet paths and improving performance for global users. It provides static IP addresses as entry points.
Why the other options are wrong
- A. An Application Load Balancer distributes traffic within a single region or VPC, not globally across regions for lowest latency access.
- B. Route 53 Latency-based Routing routes DNS queries based on perceived latency, but Global Accelerator optimizes the actual network path for the application traffic itself.
- C. Amazon CloudFront is a CDN for caching content at edge locations, which reduces latency for static content, but Global Accelerator optimizes the initial connection to dynamic applications.
AWS Global Accelerator
A networking service that improves the availability and performance of your applications with local or global users.
- Uses the AWS global network for optimized traffic routing.
- Provides static IP addresses as fixed entry points.
- Automatically re-routes traffic to healthy endpoints.
Memory trick: Accelerate global users to the closest, fastest application endpoint.
