A company has an application that is accessed by users in different countries. Which AWS service or tool will improve the application's availability and performance by routing traffic to the closest healthy endpoints?
A
AWS Direct Connect
B
AWS Global Accelerator
C
AWS Well-Architected Tool
D
AWS CLI
Explanation:
AWS Global Accelerator is the correct answer because:
Traffic Routing: Global Accelerator uses AWS's global network infrastructure to route traffic to the nearest healthy endpoint based on user location
Performance Improvement: By directing users to the closest available endpoints, it reduces latency and improves application performance
Availability: It automatically routes traffic to healthy endpoints and provides failover capabilities
Global Reach: Designed specifically for applications with users in multiple countries/regions
Why other options are incorrect:
AWS Direct Connect: Provides dedicated network connections to AWS, but doesn't route traffic based on user location
AWS Well-Architected Tool: Helps review workloads against best practices, but doesn't handle traffic routing
AWS CLI: Command-line interface for managing AWS services, not a traffic routing service
Global Accelerator is specifically designed for global applications that need improved performance and availability across multiple geographic regions.
