Concepts to understand in Terraform

• Provider:
  • Provider in Terraform will provide underlying interactions and exposes resources and Datasources to Terraform.
  • To put it in simple representation Provider is where you want infra to be created
• Resource:
  • Infrastructure element which you are creating
• Configuration Language:

  • To create infrastructure in Terraform, we need to learn configuration language

  access_key = "AKIAIH524E5KGVKCZSIQ"
  secret_key = "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"
  region = "us-west-2"
  }
  
  resource "aws_instance" "apache" {
      ami = "ami-0ec2b1175747b5db9"
      instance_type = "t2.micro"
  
  }
