Project mention: Consistently deploying Lambda functions and layers using Terraform | dev.to | 2025-12-29The Lambda module by Anton Babenko also uses base64 in its hash calculations, as well as the filename of the archive file.

For example, Anton Babenko’s module terraform-aws-modules/iam, which has a submodule iam-user.

Project mention: How Adding an Additional EBS Volume to Existing EC2 Almost Broke My Terraform AWS Workflow and Threatened Our Project Deadline | dev.to | 2025-09-17
The issue was with how the terraform-aws-modules/terraform-aws-ec2-instance module handled EBS volumes. When you modify the EBS volume configuration for an existing instance, instead of creating the new volume and attaching it (which is what you'd want), the module was treating it as a change that required instance replacement.
