An application is deployed in multiple AWS Regions worldwide. The company wants to increase the application's performance and availability. Which AWS service should they use?

AWS Global Accelerator improves application performance and availability by directing user traffic to the optimal AWS Region and endpoint via the AWS global network. It uses static IP addresses as fixed entry points, allowing for faster failover and consistent performance across multiple regions. Amazon DataZone is incorrect because it's a data management service that helps catalog, discover, and share data across an organization, not for improving application performance or availability. AWS Cloud Map is incorrect because it's a service discovery tool that maps application resources, not a global traffic routing service. AWS Auto Scaling is incorrect because while it helps maintain application availability by dynamically adjusting capacity, it operates within a single region or across Availability Zones, not globally across multiple regions to optimize traffic routing.
