The best features of Gruntwork AWS Terraform Module Libraries & Reference Architecture are that they offer production-grade option modules that are available for everything I can think of, such as VPC, EKS, RDS, ALB, NLB, or any Lambda functions, as well as the Terragrunt-first architecture, which emphasizes that DRY configs are there, remote states, and multiple account deployment can be used with that. It also maintains security best practices, including default IAM, least privileged right access, secure networking, logging, auditability, and CIS controlled network. Gruntwork AWS Terraform Module Libraries & Reference Architecture has positively impacted my organization, as previously things were done manually, but now we have everything in place. All the Terraform configurations are in the form of infrastructure as code that's available. I find Gruntwork AWS Terraform Module Libraries & Reference Architecture very good for easier management, as our whole infrastructure is there in the form of code. There are fewer chances of error because everything is in a formal structure, infrastructure as code, which can be reviewed by other people as well. The production speed and the deployment speed are quite high; if anything comes up, we don't need to go and check it. We can just write a module inside it, and it will create that thing using the other modules that are there.
