What is terraform?
The open-source Infrastructure as Code (IaC) tool Terraform, created by HashiCorp, enables DevOps developers to programmatically provision the physical resources needed for an application to execute. In addition to codifying cloud APIs into declarative configuration files, it offers a uniform command-line interface (CLI) approach to manage hundreds of cloud services. Terraform’s main features include its high-level configuration language (HCL), which IT professionals use to describe infrastructure in human-readable, declarative configuration files, and execution plans, which are created once the user describes the infrastructure.
What programming language is used in Terraform?
Enter HCL – The Language of Terraform:
At the heart of Terraform lies the HashiCorp Configuration Language (HCL). HCL is specifically designed to be both human-readable and machine-friendly, making it easier for teams to collaborate and manage infrastructure code effectively.
The syntax of HCL is straightforward and resembles JSON. It consists of key-value pairs, where the keys represent the configuration settings, and the values define the desired state.
HCL’s syntax is intuitive and easy to understand, even for those without a strong programming background. This enables team members with different skill sets to collaborate on infrastructure code effectively.
HCL code can be organized into modules, allowing you to create reusable components that represent common infrastructure patterns. These modules can be shared and leveraged across multiple projects, promoting consistency and reducing duplication.
By defining infrastructure in code, Terraform ensures that the environment remains consistent throughout its lifecycle. This eliminates manual configuration discrepancies and reduces the risk of human error.
How is Terraform from Hashicorp different
One of the key differentiators of Terraform from other IaC tools is that it is not agent-based, meaning it does not need to install any software on the managed infrastructure. This feature liberates its users from the hassle that most automation and IaC tools present. In addition, HashiCorp Configuration Language (HCL), a fully functional and immutable-based programming language, is used to create Terraform. It contains loops, of statements, variables, and much of the logic present in other programming languages.
