Terraform
Also written: IaC
Software that helps manage and build cloud infrastructure automatically. It uses code to define and provision resources.
Terraform is a tool that lets you manage your cloud computing resources, like servers and databases, using code. Instead of clicking around in a web console, you write simple configuration files that describe the infrastructure you want.
Terraform then reads these files and automatically sets up or changes your cloud resources to match your description. This makes it easier to create consistent environments, replicate them, and track changes over time. For example, you could write Terraform code to set up a web server, a database, and the network connections between them, and then apply that code to create the entire setup in your cloud account.
Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp. It allows users to define and provision infrastructure using a declarative configuration language (HCL) or JSON. Terraform works by creating a state file that tracks the current state of managed infrastructure and comparing it against the desired state defined in configuration files. It then generates an execution plan detailing the actions needed to reach the desired state and applies those changes.
Key benefits include idempotency, enabling safe and predictable updates, and support for numerous cloud providers and services through a plugin architecture (providers). Tradeoffs involve the complexity of managing state, especially in collaborative environments, and the learning curve for its declarative approach.

Terraform was created by HashiCorp, first released in 2014. It emerged from the need for a consistent way to manage infrastructure across different cloud providers and on-premises environments. Source ↗
You can try Terraform by installing it and writing a simple configuration file to create a resource, like a small file on your local machine or a storage bucket in a cloud provider if you have an account. Then, run `terraform init`, `terraform plan`, and `terraform apply` to see it create the resource. Finally, run `terraform destroy` to remove it.

Questions people ask
- What is Infrastructure as Code?
- Infrastructure as Code (IaC) is the practice of managing and provisioning IT infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
- Is Terraform free?
- Terraform has an open-source core that is free to use. HashiCorp also offers paid enterprise versions with additional features for larger organizations.
