To front an EC2 instance with Global Accelerator, you simply create an accelerator and add the EC2 instance as an endpoint using the EC2 instance ID. To control what internet traffic reaches your EC2 instance, we recommend you use security groups in your Amazon Virtual Private Cloud. Additionally, Global Accelerator preserves the source IP address of the client all the way to the EC2 instance, which enables you to apply client-specific logic and serve personalized content for your TCP and UDP applications.
We are also pleased to announce that Global Accelerator now automatically creates two fully-qualified domain name (FQDN) A records and two pointer (PTR) records for each newly-created accelerator. These records have been generated for your existing accelerators as well. Until now, you had to create Domain Name System (DNS) entries manually. Now, Global Accelerator automatically generates DNS entries for you to use with Amazon Route 53 or with the DNS provider of your choice. Furthermore, to route custom domain traffic to your accelerator you can create Route 53 alias records.
There are no additional Global Accelerator charges for either EC2 instance support or DNS aliasing support. EC2 instance endpoints are supported in US East (N. Virginia), US East (Ohio), US West (Oregon), US West (Northern California), Europe (Ireland), Europe (Frankfurt), Europe (London), Asia Pacific (Tokyo), Asia Pacific (Singapore), Asia Pacific (Seoul), Asia Pacific (Sydney), and Asia Pacific (Mumbai) AWS Regions.
