What functionality does AWS Global Accelerator provide for applications deployed globally?

AWS Global Accelerator is designed specifically to enhance the performance and availability of applications that are deployed across multiple global regions. It achieves this by directing user traffic to the optimal endpoint based on health, geography, and routing policy.

By using the AWS global network, Global Accelerator provides a more consistent and reliable experience for users, significantly reducing latency and improving application performance. It intelligently routes user traffic to the nearest AWS Region, ensuring that requests are processed quickly and efficiently. Additionally, it offers built-in health checks that help to automatically divert traffic away from unhealthy endpoints and towards the healthy ones, thereby ensuring higher availability of the application.

The other options do not align with the core functionalities of AWS Global Accelerator. While increasing server storage, reducing costs, and encrypting data in transit are important considerations in application architecture, they do not accurately describe the primary purpose and benefits of Global Accelerator. Its main focus is on improving the performance and availability, making it a critical service for global applications.
