Implementing Certificate Manager in AWS

Implementing Certificate Manager in AWS


In the vast world of cloud computing, security is paramount. Securing your applications and websites with SSL/TLS certificates is a crucial step in ensuring the confidentiality and integrity of data. Amazon Web Services (AWS) provides a simple yet powerful service called AWS Certificate Manager (ACM) that makes the process of managing and deploying SSL/TLS certificates a breeze. In this blog post, we'll walk you through the basics of implementing Certificate Manager in AWS.

Step 1: Access AWS Certificate Manager

  1. Log in to AWS Console: Start by logging in to your AWS Management Console. If you don't have an AWS account, you'll need to sign up.

  2. Navigate to ACM: Once logged in, find the "Certificate Manager" service. You can either use the search bar or locate it under the "Security, Identity, & Compliance" section.

Step 2: Request a Certificate

  1. Click "Request a certificate": In the ACM dashboard, click the "Request a certificate" button.

  2. Choose the certificate type: Select the type of certificate you need: either a public certificate for use with websites and other public-facing services, or a private certificate for internal services.

  3. Add domain names: Enter the domain names you want to secure. ACM will automatically validate your ownership of these domains.

  4. Select validation method: Choose a validation method (DNS validation or Email validation). DNS validation is usually more straightforward, as it only requires adding a DNS record.

Step 3: Domain Validation

  1. Complete DNS validation (if chosen): If you opted for DNS validation, follow the instructions provided by ACM to add the required DNS records to your domain's DNS configuration.

  2. Email validation (if chosen): If you selected email validation, follow the instructions in the email sent to the domain's registrant, admin, and technical contacts.

Step 4: Certificate Issued

  1. Wait for validation: ACM will take some time to validate your domain ownership. Once validated, the status will change to "Issued."

  2. Certificate details: Click on the certificate to view its details. Here, you can find the certificate ARN, expiration date, and other relevant information.

Step 5: Deploy Certificate

  1. Integration with AWS Services: ACM integrates seamlessly with other AWS services like Amazon CloudFront, Elastic Load Balancer (ELB), and API Gateway. Choose the service where you want to deploy your certificate.

  2. Select certificate: When configuring the chosen service, you'll be prompted to select a certificate. Choose the one you just created in ACM.

  3. Complete configuration: Follow the service-specific steps to complete the configuration, and your SSL/TLS certificate will be applied.


Implementing Certificate Manager in AWS is a fundamental step in securing your applications and services. With its user-friendly interface and seamless integration with other AWS services, ACM makes the process efficient and straightforward. By following the steps outlined in this guide, you'll be well on your way to enhancing the security of your AWS-hosted resources.
