The Terraform Awakens: Infrastructure as Code Quest

Short summary

Infrastructure as Code using Terraform or CloudFormation lets teams version-control cloud infrastructure and preview changes before deployment. This guide compares the two tools side-by-side with working examples for building a VPC, security groups, and subnets. Key takeaway: declare your desired infrastructure state rather than clicking through the console, and always version-lock dependencies to avoid configuration drift and breaking changes.

• •Terraform and CloudFormation both enable declarative infrastructure provisioning with version control and plan previews
• •Terraform is cloud-agnostic; CloudFormation is AWS-native with built-in drift detection but more verbose syntax
• •Always pin provider versions and avoid hard-coding secrets to prevent breaking changes and security issues
