AWS re:Post Knowledge Center Spotlight: AWS Certificate Manager (ACM)
This spotlight on ACM equips you with the skills and troubleshooting tips to get the most out of a powerful service.
The AWS re:Post Knowledge Center is your one-stop-shop for authoritative, up-to-date guidance on using AWS services. This month, we're highlighting AWS Certificate Manager (ACM), a service that helps you to provision, manage, and renew public and private SSL/TLS certificates for your AWS websites and applications.
With ACM, you can provide certificates for your integrated AWS services by issuing them directly or importing third-party certificates.
Renewing certificates
ACM continuously monitors the expiration dates of the certificates it manages. It will initiate the renewal process for a certificate approximately 60 days before its expiration date. For eligible certificates, ACM will automatically renew the certificate before it expires, without any manual intervention required. The following articles help to explain how to check the renewal status and renew your certificates.
