AWS Certificate Manager is a service that makes it easier to enable, manage, and deploy public and private SSL/TLS certificates for use with AWS services.
Step 1 - Import a certificate
You can use AWS Certificate Manager certificates with other AWS Services like Elastic Load Balancing, Amazon CloudFront, AWS Elastic Beanstalk, Amazon API Gateway, AWS CloudFormation.
In the AWS ACM console, choose "Import a certificate". Paste the "Certificate body", "Certificate private key", and "Certificate chain"(optional) and save the certificate.
The certificate names in the recovery region should match with available certificates in the primary region.
Note
During recovery, the HTTPS rules in the Application Load Balancer will be ignored. Please import the required certificates in the recovery region and tag them appropriately to resolve the issue.*
Step 2 - Add Tags
Users can add one or more user-defined tags to the certificate by using a key-value pair. The user-defined tags can be applied to one or more certificates.
Add the same tags to the load balancer in both the Primary and the Recovery Region.
Step 3 - Review and import
Choose “Review and import” to review the information about your certificate, and choose "Import".
Associate Certificate with Load Balancer
ACM can be created or imported and associated with the Classic, Application, or Network Load Balancers.
Note
ACM certificates must be requested or imported in the same AWS region as the load balancer.
You can use any of your certificates in ACM(Recommended) or IAM.
Using ACM in Load Balancer
Choose the ACM option to manage the certificates. ACM is the preferred tool to maintain the certificates.
Using IAM in Load Balancer
IAM can also be selected to manage the certificates.
