The following article explains the difference between Terraform and other IaC tools.
Terraform is just one of several popular infrastructure-as-code tools available today. Below are some key differences between Terraform and other infrastructure-as-code tools.
- configuration language. Terraform uses a custom declarative language called HashiCorp Configuration Language (HCL) to configure infrastructure resources, while other tools like Ansible, Chef, and Puppet use their own configuration languages or rely on existing scripting languages like Python, Ruby, or YAML.
- Cloud platform support. Terraform is cloud agnostic and supports provisioning across multiple cloud platforms such as AWS, Azure and Google Cloud, while other tools such as AWS CloudFormation and Google Cloud Deployment Manager are specific to a single cloud platform.
- resource dependence. Terraform has built-in support for managing dependencies between resources, so it can automatically order the allocation and deletion of resources to avoid conflicts, while other tools may require manual dependency management.
- State administration. Terraform uses a state file to track the current state of infrastructure resources, allowing it to perform incremental updates and maintain a consistent infrastructure state, while other tools may require manual monitoring of resource states.
- Community support. Terraform has a large and active community of users and contributors, with a wide variety of pre-built modules and plugins, while other tools may have smaller communities and limited module support.
In general, Terraform’s agnostic approach, support for dependency management, and Terraform’s state management make it a popular choice for infrastructure-as-code, but the choice of tool will ultimately depend on the specific needs of the organization and the resources provided.
