What Is Amazon Certificate Manager?

Amazon Certificate Manager (ACM) handles the complexity of creating, storing, and renewing public and private SSL/TLS X.509 certificates and keys that protect your Amazon websites and applications. You can provide certificates for your integrated Amazon services either by issuing them directly with ACM or by importing third-party certificates into the ACM management system. ACM certificates can secure singular domain names, multiple specific domain names, wildcard domains, or combinations of these. ACM wildcard certificates can protect an unlimited number of subdomains. You can also export ACM certificates signed by Amazon Private CA for use anywhere in your internal PKI.

Note

ACM is not intended for use with a stand-alone webserver. If you want to set up a stand-alone secure server on an Amazon EC2 instance, the following tutorial has instructions: Configure SSL/TLS on Amazon Linux 2023.
