Amazon Web Services (AWS) Certificate Manager (ACM) is a service that lets you easily provision, manage, and deploy Secure Sockets Layer/Transport Layer Security (SSL/TLS) certificates for use with AWS services. SSL/TLS certificates are used to secure network communications and establish the identity of websites over the internet.
With ACM, you can request a certificate, deploy it on AWS resources such as Elastic Load Balancers or Amazon CloudFront distributions, and let ACM handle the certificate renewal process. ACM provides a central location to manage the SSL/TLS certificates for your AWS resources, making it easier to secure your applications.
In terms of architecture, ACM integrates with other AWS services to make it easy to use SSL/TLS certificates with your applications. For example, you can use ACM to provision and manage SSL/TLS certificates for use with Amazon CloudFront distributions, Elastic Load Balancers, and API Gateway APIs. ACM also provides an API that you can use to request and manage SSL/TLS certificates programmatically.
In addition to SSL/TLS certificates, ACM also provides support for managing Internet Protocol version 6 (IPv6) certificates. These certificates can be used to secure connections between clients and servers over IPv6 networks.
