description AWS Global Accelerator Overview

Global Accelerator improves the performance and resilience of user-facing applications by routing traffic to the nearest AWS edge location, rather than relying solely on public internet paths. In a DR scenario, it can be configured to automatically shift traffic away from a failing region's public IP endpoints to a healthy, secondary region's endpoints, providing superior failover performance compared to standard DNS changes.

help AWS Global Accelerator FAQ

How does AWS Global Accelerator improve application performance?

Instead of relying on unpredictable public internet paths, it routes user traffic directly to the nearest AWS edge location via the Amazon global network. This drastically reduces latency and packet loss, providing a smoother experience for global users.

Can AWS Global Accelerator be used for disaster recovery?

Yes, in a DR scenario, you can configure it to automatically shift traffic away from a failing primary endpoint to a healthy backup endpoint. This traffic steering happens at the AWS edge, ensuring client connections drop and reconnect seamlessly.

Do I need to change my application's IP address to use AWS Global Accelerator?

No, the service provides you with two static anycast IP addresses that serve as a fixed entry point for your users. Traffic hitting these IPs is immediately routed by AWS to your actual application endpoints, allowing your underlying infrastructure to scale or change without user disruption.

What is the difference between AWS Global Accelerator and Amazon CloudFront?

CloudFront is a Content Delivery Network primarily used to cache static assets like images and videos closer to end-users. Global Accelerator focuses on improving performance and resilience for dynamic, non-cacheable user-facing applications like gaming or live video streaming.
