This addition enables use of standard ACME clients such as Certbot or cert-manager to request and manage public TLS certificates issued by Amazon Trust Services, simplifying certificate lifecycle management especially ahead of mandatory short (47-day) lifetimes by 2029.

Previously unavailable in GovCloud regions, this capability helps organizations in government and regulated sectors automate security practices and improve compliance. It offers full integration with existing ACM workflows without manual renewal overhead.
