What is Terraform?

Terraform by HashiCorp is an open-source infrastructure as code (IaC) tool that lets us define, manage, and automate cloud infrastructure using a declarative (human-readable) configuration language called HashiCorp Configuration Language (HCL) across multiple cloud providers like Amazon Web Services (AWS), Azure, Google Cloud, and even on-premises data centers.

Key Features of Terraform

1. Manage any infrastructure: Terraform can interact with cloud platforms and multiple providers such as AWS, Azure, Google Cloud, Kubernetes, VMware, GitHub, and many more to manage resources.

2. Standardize your deployment workflow:

• Write Configuration We Define infrastructure in .tf files.

• Initialize Terraform Set up the working directory and download provider plugins by running terraform init.

• Terraform plan Preview changes Terraform will make to match your configuration by running terraform plan. This stimulates better control over your environment.

• Terraform apply Create or update infrastructure as defined. By simply running terraform apply, you will be able to make the planned changes.

3. Collaboration: With Terraforms remote state backends, you can securely share your state with your teammates and provide a stable environment for Terraform to run in.

4. Version Control: You can connect Terraform to version control systems (VCSs) like GitHub, GitLab, and others, allowing you to manage changes to your infrastructure through version control, as you would with application code.
