AWS Certificate Manager
AWS Certificate Manager (ACM) is a managed service that simplifies the provisioning, deployment, and renewal of SSL/TLS certificates for use with AWS services and internal connected resources. It automates the complex process of certificate lifecycle management, including issuance, renewal, and revocation, while integrating seamlessly with services like Elastic Load Balancing, Amazon CloudFront, and API Gateway. ACM provides free public SSL/TLS certificates and supports private certificates for internal applications.
Developers should use ACM when deploying web applications on AWS that require HTTPS encryption, as it eliminates the manual overhead of purchasing, uploading, and renewing certificates from third-party authorities. It is ideal for use cases involving load balancers, content delivery networks (CloudFront), or APIs where security and automation are priorities, such as e-commerce sites, SaaS platforms, or microservices architectures. ACM reduces costs and operational risks by handling certificate expiration and compliance automatically.
