Terraform

• Software isn’t done until you deliver it to the customers.
• What Terraform Does?
  

Infrastructure as code (IAC)

• The idea behind IAC is that you write & execute the code to define, deploy, update and destroy your infrastructure
• Consider the following as the architecture of Redbus Application
  
• Now lets assume RedBus is working on AWS
  
• Now lets assume Redbus is working on Azure
  

# AWS
resource "aws_instance" "app" {
    instance_type       = "t2.micro"
    ami                 = "ami-892347389247"
    availability_zone   = "us-west-2a"
}

# Azure 
resource "azurerm_vm" "app" {
    size                = "Standard_B1s"
    vmimage             = "ubuntu2004LTS"
    location            = "eastus"
}

#vmware

resource "vmware_vm" "app"  {
    cpu     = "2"
    ram     = "4GB"
    image   = "ubuntu"  
}

• The major concepts of terraform are
  • Provider:
    • Where we can create infrastructure
  • Resource:
    • What has to be created
  • DataSource:
    • Query information about anything in the Provider
• Relevance of Terraform in CI/CD Pipeline
