AWS Global Accelerator​

There are few use cases that can leverage the features provided by AWS Global Accelerator.

  • Associate the static IP addresses provided by AWS Global Accelerator to regional AWS resources or endpoints, such as Network Load Balancers, Application Load Balancers, EC2 Instances, and Elastic IP addresses. The IP addresses are anycast from AWS edge locations so they provide onboarding to the AWS global network close to your users.
  • Easily move endpoints between Availability Zones or AWS Regions without needing to update your DNS configuration or change client-facing applications.
  • Dial traffic up or down for a specific AWS Region by configuring a traffic dial percentage for your endpoint groups. This is especially useful for testing performance and releasing updates.
  • Control the proportion of traffic directed to each endpoint within an endpoint group by assigning weights across the endpoints.
  • For other use cases, check AWS Global Accelerator

Multi-Region applications​

You can use AWS Global Accelerator to bring down the number of IP addresses allowed by the firewall and easily manage the entire network infrastructure with a situation that it is too many ALBs in multiple AWS Regions.
