Key difference between Terraform & CloudFormation

Key difference between Terraform & CloudFormation

Choosing the right infrastructure-as-code tool can be a strategic decision for any DevOps team. In this post, we compare two of the most popular tools: Terraform by HashiCorp and CloudFormation by AWS.

You’ll learn that while CloudFormation is deeply integrated with AWS and offers native support for most AWS services, Terraform provides a multi-cloud, provider-agnostic approach. Terraform uses its own language (HCL) and offers features like reusable modules, a larger ecosystem of community plugins, and simpler cross-cloud deployments.

We dive into areas like:

  • Syntax and configuration structure
  • State management and drift detection
  • Modularity and reusability
  • Error handling and rollback support
  • Ecosystem and toolchain compatibility

This post helps you decide which tool is right for your project, whether you’re all-in on AWS or working across multiple cloud platforms.

Learn Terraform in 20 mins

In just 20 minutes, you’ll get a hands-on introduction to Terraform, HashiCorp’s powerful IaC tool. You’ll start with installing Terraform on your system and writing your very first .tf file. You’ll then create and deploy a resource—such as an EC2 instance or S3 bucket—using the core Terraform commands: init, plan, and apply.

We’ll break down the basic syntax of HCL (HashiCorp Configuration Language), how to configure providers like AWS, and how Terraform handles resource states and dependencies.

This guide is ideal for developers, students, or sysadmins looking for a crash course in Terraform. By the end, you’ll have a foundational understanding and confidence to build simple cloud infrastructure using code.

Terraform Best Practices

Terraform has become the go-to tool for managing infrastructure as code. However, writing effective Terraform code requires more than just knowing the syntax—it involves following best practices to ensure scalability, security, and collaboration.

In this post, you’ll explore essential Terraform best practices that every DevOps engineer and cloud architect should follow. We cover how to use remote state storage with state locking, ensuring your infrastructure remains consistent even in team environments. You’ll also learn how to organize your configuration into modules for better reusability and how to structure environments to avoid conflicts.

Other key areas include naming conventions, version control, tagging strategies, securing sensitive variables, and integrating Terraform into CI/CD pipelines. By following these practices, you’ll build infrastructure that’s not just functional but also robust, maintainable, and production-ready.

Whether you’re working on AWS, Azure, or GCP, these practices will help you scale your IaC efforts efficiently.
