What is AWS Certificate Manager (ACM)?

AWS Certificate Manager (ACM) is a service provided by Amazon Web Services (AWS) that simplifies and automates the management of SSL/TLS certificates. SSL/TLS are critical security protocols that encrypt data transmitted between servers and browsers, protecting sensitive information from being compromised.

Key Benefits of ACM with SSL

  • Automated certificate management: ACM automatically creates, issues, and renews SSL/TLS certificates without manual intervention, reducing the risk of expired certificates and lessening the administrative burden.
  • Strong security: ACM ensures that all connections to your applications and websites are encrypted with SSL/TLS, protecting user data during transmission.
  • Easy integration with AWS services: ACM seamlessly integrates with other AWS services like Elastic Load Balancing, Amazon CloudFront, and Amazon API Gateway, allowing quick deployment of SSL/TLS certificates without complex configurations.
  • Free public certificates: ACM provides free public SSL certificates for domains used within AWS, saving costs for businesses.

Using AWS Certificate Manager (ACM) is an ideal solution for applications and websites requiring strong, automated, and efficient security on the AWS platform.
