launching-ec2-instance-with-best-practices

To launch an EC2 instance with secure defaults, you need to enforce IMDSv2, configure encrypted gp3 EBS root volumes, and apply least-privilege IAM roles. This workflow validates VPC subnet placement and builds hardened security group ingress rules.

The best way to set up least-privilege IAM for an EC2 instance is to create a dedicated IAM role and instance profile with only necessary permissions. This process defaults to SSM Session Manager for access when SSH is not explicitly requested.

To configure encrypted EBS storage for an EC2 instance, you enforce encrypted gp3 EBS volumes during the launch workflow. This ensures your root volume meets security requirements for data at rest.

Yes, you can use SSM Session Manager instead of SSH for EC2 instance access. The provisioning workflow defaults to SSM Session Manager when SSH access is not requested, avoiding open SSH ports and improving security.

To apply consistent resource tagging to EC2 instances, you use a standardized tagging strategy during launch. This applies tags for cost tracking, ownership, and automation readiness to ensure governance across your cloud resources.

Yes, this EC2 launch workflow includes guardrails for termination protection and CloudWatch monitoring. It also enforces IMDSv2 and provides post-launch verification and troubleshooting guidance.
