AWS Certificate Manager Now Supports ACME in GovCloud Regions
AWS Certificate Manager (ACM) now supports the ACME protocol in AWS GovCloud (US-East) and AWS GovCloud (US-West), letting you automate public TLS certificate issuance and renewal with any ACMEv2-compatible client like Certbot, cert-manager, or acme.sh. This fully managed solution helps you stay ahead of the CA/Browser Forum's upcoming 47-day certificate lifetime requirement without manual certificate juggling.
