Amazon Managed Service for Prometheus now supports VPC endpoint policies configured using Amazon Virtual Private Cloud (Amazon VPC). Amazon Managed Service for Prometheus is a fully managed Prometheus-compatible monitoring service that monitors and alarms on operational metrics at scale. It does this without you having to manage the underlying infrastructure required to scale and secure the ingestion, storage, alerting, and querying of metrics. With this feature, customers can now configure VPC endpoint policies in the Amazon VPC console, via Command Line Interface or SDK, or through AWS CloudFormation. These policies can restrict access of Amazon Managed Service for Prometheus endpoints to particular AWS accounts, IAM users, and IAM roles.
