ACM now supports ACME for public certificates in AWS GovCloud (US)

AWS Certificate Manager (ACM) ACME protocol support is now available in AWS GovCloud (US-East) and AWS GovCloud (US-West), providing a fully managed ACME server endpoint that issues public TLS certificates from Amazon Trust Services using any ACMEv2-compatible client, including Certbot, cert-manager for Kubernetes, and acme.sh. With the CA/Browser Forum mandating 47-day certificate lifetimes by 2029, manual management of public certificates becomes untenable. ACME support in ACM gives developers a standards-based path to fully automate certificate issuance and renewal.
