What service handles the complexity of creating, storing, and renewing public and private SSL/TLS certificates?

AWS Certificate Manager (ACM) is specifically designed to simplify the process of creating, managing, and renewing SSL/TLS certificates. ACM automates the provisioning and deployment of these certificates for use with AWS services and your internal resources. This automation includes the complexities of renewal processes, which can often be cumbersome and error-prone when done manually. By utilizing ACM, users can ensure their websites and applications are secure, as ACM will automatically renew certificates before they expire.

In contrast, AWS Identity and Access Management (IAM) focuses on managing access to AWS services and resources securely, and does not handle the management of SSL/TLS certificates. AWS Network Firewall is a managed firewall service that provides protection for virtual networks but does not deal with SSL/TLS certificates. AWS Firewall Manager is a security management service that simplifies AWS WAF and Shield Advanced administration, but it too is not concerned with the management of SSL/TLS certificates. Thus, ACM stands out as the dedicated service for efficiently handling SSL/TLS certification needs on AWS.
