what is Terraform explain with example.


Terraform is an open-source infrastructure as code software tool that allows you to define and provision your infrastructure resources using high-level configuration files called Terraform configurations. These configurations are written in HashiCorp Configuration Language (HCL), which is a domain-specific language for expressing infrastructure as code.
With Terraform, you can manage popular service providers as well as custom in-house solutions. You can define the desired state of your infrastructure in Terraform configurations, and Terraform will automatically create, update, and delete resources to reach the desired state. This means you can version control your infrastructure, test changes before applying them, and roll back changes if necessary, making it easier to manage your infrastructure at scale.
Here's a simple example to demonstrate how Terraform works:

provider "aws" {
  region = "us-west-2"

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"

This example creates an Amazon Web Services (AWS) EC2 instance using the specified Amazon Machine Image (AMI) and instance type. The provider block specifies the AWS provider and the region in which to create the instance. The resource block specifies the type of resource to create (an EC2 instance) and assigns it a name (example).
You can run terraform apply to create the EC2 instance, and Terraform will output the changes it made to your infrastructure. To delete the instance, you can run terraform destroy.
