Yes, AWS Global Accelerator can be integrated with other AWS services like AWS Lambda and Amazon API Gateway, enabling improved performance, availability, and static IP address usage for your applications.
Integration with Amazon API Gateway
AWS Global Accelerator can front an Amazon API Gateway to provide static IP addresses for your API endpoints. This is particularly useful in scenarios where clients or security policies require fixed IP addresses for safelisting. Since API Gateway endpoints are typically dynamic and do not have static IPs, Global Accelerator offers a solution by providing two static anycast IP addresses that serve as fixed entry points to your API.
The typical architecture involves configuring AWS Global Accelerator with an Application Load Balancer (ALB) as an endpoint. The ALB then routes traffic to the API Gateway, which can be configured with a custom domain name and secured with AWS Certificate Manager. This setup allows your API Gateway to be accessed via static IPs provided by Global Accelerator, improving both security posture and performance by routing traffic over the AWS global network infrastructure.
This approach is well-suited for regulated industries such as healthcare and financial services, where firewall rules require IP safelisting. It also benefits from Global Acceleratorâs health checks and failover capabilities to route traffic only to healthy endpoints[6][7].
Integration with AWS Lambda
While AWS Global Accelerator does not directly target Lambda functions as endpoints, it can be integrated indirectly through API Gateway or Application Load Balancers that invoke Lambda. For example, you can expose Lambda functions via API Gateway, and then front the API Gateway with Global Accelerator to provide static IP addresses and improved global performance.
Additionally, Lambda functions can be used in conjunction with Global Accelerator for automation tasks such as dynamically updating endpoint groups in response to scaling events or health changes. For instance, a Lambda function can be triggered by CloudWatch Events to update Global Accelerator endpoint groups when EC2 instances are launched or terminated, ensuring traffic is routed only to healthy and available endpoints[4].
Summary
- AWS Global Accelerator provides static IP addresses and global traffic routing over the AWS network.
- It can be integrated with Amazon API Gateway by placing an Application Load Balancer between Global Accelerator and API Gateway, enabling static IP access to APIs.
- Lambda functions can be integrated indirectly via API Gateway or ALB, and can also be used to automate Global Accelerator endpoint management.
- This integration enhances security (static IPs for safelisting), availability (health checks and failover), and performance (routing over AWS global network)[6][7][4].
This combination is ideal for applications requiring global reach, static IP addresses, and integration with serverless or API-driven architectures.
