AWS Global Accelerator

Improve global application availability and performance using the AWS global network

AWS Global Accelerator is a networking service that improves the availability and performance of the applications that you offer to your global users.

Today, if you deliver applications to your global users over the public internet, your users might face inconsistent availability and performance as they traverse through multiple public networks to reach your application. These public networks can be congested and each hop can introduce availability and performance risk. AWS Global Accelerator uses the highly available and congestion-free AWS global network to direct internet traffic from your users to your applications on AWS, making your users’ experience more consistent.

To improve the availability of your application, you must monitor the health of your application endpoints and route traffic only to healthy endpoints. AWS Global Accelerator improves application availability by continuously monitoring the health of your application endpoints and routing traffic to the closest healthy endpoints.

AWS Global Accelerator also makes it easier to manage your global applications by providing static IP addresses that act as a fixed entry point to your application hosted on AWS which eliminates the complexity of managing specific IP addresses for different AWS Regions and Availability Zones. AWS Global Accelerator is easy to set up, configure and manage.

Introduction to AWS Global Accelerator


Improve global application availability

AWS Global Accelerator continually monitors the health of your application endpoints, such as your Network Load Balancers, Application Load Balancers, or Elastic IPs, instantly reacting to changes in their health or configuration. AWS Global Accelerator will then redirect user traffic to healthy endpoints that deliver the best performance and availability to your users.

Accelerate your global applications

AWS Global Accelerator optimizes the network path, taking advantage of the vast, congestion-free AWS global network. Regardless of where your users are located, AWS Global Accelerator intelligently routes traffic to the endpoint that provides the best application performance.

Easily manage endpoints

AWS Global Accelerator’s static IP addresses make it easy to move endpoints between Availability Zones or AWS Regions without needing to update your DNS configuration or change client-facing applications.

How it works


Directly access web applications

Without AWS Global Accelerator


It can take many networks to reach the application. Paths to and from the application may differ. Each hop impacts performance and can introduce risks.

With AWS Global Accelerator


Adding AWS Global Accelerator removes these inefficiencies. It leverages the Global AWS Network, resulting in improved performance.

Use cases

Disaster recovery

You need to rely on your network to always be available. If there is an application failure in the primary AWS Region or endpoints, AWS Global Accelerator instantly re-routes traffic to a secondary AWS Region or endpoint.

Support latency-sensitive applications

Many applications, such as gaming, media, mobile applications, and financial applications, need very low latency for a great user experience. To improve performance for your users, AWS Global Accelerator directs traffic to edge locations that are nearest to users, routing that traffic to the closest endpoint. AWS Global Accelerator quickly reacts to changes in endpoint performance improving your users’ application performance. 

Scale your network to support more users

As your application usage grows, you need to scale and adapt your network. AWS Global Accelerator allows you to scale your network up or down, easily adding or removing endpoints without needing to update the IP addresses in your client applications. AWS Global Accelerator lets you associate regional resources to static IP addresses and whitelist these addresses in your client applications, firewalls, and DNS records.
