Quotas - Amazon Private Certificate Authority
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Quotas

Amazon Private CA assigns quotas to your allowed number of certificates and certificate authorities. Request rates for API actions are also subject to quotas. Amazon Private CA quotas are specific to an Amazon account and Region.

Amazon Private CA throttles API requests at different rates depending on the API operation. Throttling means that Amazon Private CA rejects an otherwise valid request because the request exceeds the operation's quota for the number of requests per second. When a request is throttled, Amazon Private CA returns a ThrottlingException error. Amazon Private CA does not guarantee a minimum request rate for APIs.

To see what quotas can be adjusted, see the Amazon Private CA quotas table in the Amazon Web Services General Reference.

You can view your current quotas and request quota increases using Amazon Service Quotas.

Amazon Private CA is integrated with Amazon Certificate Manager. You can use the ACM console, Amazon CLI, or ACM API to request private certificates from an existing private CA. These private PKI certificates, which are managed by ACM, are subject both to PCA quotas and to the quotas that ACM places on public and imported certificates. For more information about ACM requirements, see Request a Private Certificate and Quotas in the Amazon Certificate Manager User Guide.
