Installing ACM certificates - AWS Certificate Manager

Installing ACM certificates

You cannot use ACM to install a public certificate directly on your AWS based website or application. You must use one of the services integrated with ACM. For more information, see Services integrated with AWS Certificate Manager.

ACM certificates signed by a CA in ACM Private CA and intended for your private PKI can be exported and installed manually on any system where you have administrative access. These certificates are not trusted on the public internet.
