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).

Installing ACM certificates

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

ACM certificates signed by a CA in Amazon 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.
