Centrally manage certificates on the AWS Cloud
You will find it easy to centrally manage AWS Certificate Manager SSL/TLS certificates provided by AWS Certificate Manager in an AWS Region from the AWS Management Console, AWS CLI, or AWS Certificate Manager APIs. You can also audit the use of each certificate by reviewing your Amazon CloudTrail logs.
Secure key management
AWS Certificate Manager is designed to protect and manage the private keys used with SSL/TLS certificates. Strong encryption and key management best practices are used when protecting and storing private keys.
Integrated with other AWS cloud services
AWS Certificate Manager is integrated with other AWS services, so you can provision an SSL/TLS certificate and deploy it with your Elastic Load Balancer or API in Amazon API Gateway. AWS Certificate Manager also works with AWS Elastic Beanstalk and AWS CloudFormation for public email-validated certificates to help you manage public certificates and use them with your applications in the AWS Cloud. To deploy a certificate with an AWS resource, you simply select the certificate you want from a drop-down list in the AWS Management Console. Alternatively, you can call an AWS API or CLI to associate the certificate with your resource. AWS Certificate Manager then deploys the certificate to the selected resource for you.
Import third-party certificates
AWS Certificate Manager makes it easy to import SSL/TLS certificates issued by third-party Certificate Authorities (CAs) and deploy them with your Elastic Load Balancers and APIs on Amazon API Gateway. You can monitor the expiration date of an imported certificate and import a replacement when the existing certificate is nearing expiration. Alternatively, you can request a free certificate from AWS Certificate Manager and let AWS manage future renewals for you. Importing certificates doesn't cost anything.
