AWS Resource Group APIs now come with AWS PrivateLink support, allowing you to invoke AWS Resource Group APIs from within your Amazon Virtual Private Cloud (VPC) without traversing the public internet.
AWS Resource Groups enables you to model, manage and automate tasks on large numbers of AWS resources by using tags to logically group your resources. You can create logical collections of resources such as applications, projects, and cost centers, and manage them on dimensions such as cost, performance, and compliance in AWS services such as myApplications, AWS Systems Manager and Amazon CloudWatch.
AWS PrivateLink support for AWS Resource Groups is available in all AWS Regions where AWS Resource Groups is available. To get started, follow the directions provided in the AWS PrivateLink documentation or visit AWS Resource Groups.
