AWS Certificate Manager (ACM) Private Certificate Authority (CA) has increased the limits per account for certificate creation and certificate revocation. The limits on the lifetime total certificates generated and revoked by a single CA has been increased from 50,000 to 1,000,000. This applies to all regions for which ACM Private CA is available. This limit increase is intended for organizations doing large scale certificate deployment to IOT, endpoints, and devices.

ACM Private CA is a managed private CA service that helps you easily and securely manage the lifecycle of your private certificates. ACM Private CA provides you a highly-available private CA service without the upfront investment and ongoing maintenance costs of operating your own private CA. ACM Private CA extends ACM’s certificate management capabilities to private certificates, enabling you to manage public and private certificates centrally.

For a list of regions where ACM Private CA is available, see the AWS Region Table.

To get started, first time ACM Private CA customers can try the service for 30 days with no charge for the operation of their first CA. Visit the ACM Private CA website to learn more about ACM Private CA.
