Description

AWS Certificate Manager (ACM) is a service that lets you easily provision, manage, and deploy public and private Secure Sockets Layer/Transport Layer Security (SSL/TLS) certificates for use with AWS services and your internal connected resources.

How It Works

ACM handles the complexity of creating and managing public SSL/TLS certificates. You simply request a certificate, deploy it on AWS resources or export it to use on your server, and ACM takes care of the rest.

Benefits

• Simplified Management: ACM automates time-consuming processes such as certificate renewals.
• Secure: ACM certificates are trusted by most modern browsers, operating systems, and devices.
• Cost-Efficient: Public SSL/TLS certificates provisioned through ACM are free.

Limitations

• Limited Customization: ACM may not support all features of SSL/TLS certificates.
• AWS Ecosystem: Certificates can only be used with eligible AWS services.
• Geographical Restrictions: ACM is not available in all AWS regions.

Features

• Automatic Renewal: ACM automatically renews managed certificates before they expire.
• Integrated with AWS: ACM is integrated with other AWS services like Elastic Load Balancing, Amazon CloudFront, and more.
• Private Certificate Authority: ACM Private CA allows you to create private certificate authority hierarchies, including root and subordinate CAs.

Use Cases

• Securing Websites: ACM is used to secure websites hosted on AWS with SSL/TLS certificates.
• Internal Communications: ACM Private CA can be used to secure internal communications within an organization.
