Assignment – 1: List of Components of Terraform and explain each components with 1 image Terraform has two important components: Terraform Core and Terraform Plugins. Terraform Core oversees the reading and interpolation of resource plan executions, resource graphs, state management features and configuration files. Core is composed of compiled binaries written in the Go programming language. Each compiled binary acts as a command-line interface (CLI) for communicating with plugins through remote procedure calls (RPC). Terraform Plugins are responsible for defining

Assignment 1 – List of Components of Terraform and explain each components with 1 image Terraform is a IaaC – Infrastructure as a code. Its common tool/code standard or language for tools to create the infrastructure. Language – Terraform written in GO language and can be integrate with aroud 2255 applications/tools. Terraform is owned by Harshicorp. HCL – Harshicorp configuration Language, Terraform enables users to use configuration language called HCL to describe the desire (what we want) state in cloud

Assignment – 1 List of Components of Terraform and explain each components with 1 image 1.Terraform Code (HCL) Terraform code is expressed as a declarative code which contains declaration of resources, providers and necessary code for infrastructure deployment and management acting as single input source file for terraform executable. 2. Terraform Executable Terraform Executable provides command line interface tool that will allow developer to run / perform all the terraform commands on terraform project/code. Following are mostly used Terraform commands:

Assignment 2- Write a terraform file which must create 1 azure resources group + 1 aws instance and 1 github repo. All the code must be into 1 file including providers.

Prerequisite System ( Windows or Linux) Terraform setup file Azure CLI Access to Azure provider( Subscription) Git Bash / PowerShell Notepad ++ or any code Editor Setup to execute the terraform code from git bash CLI. to create an azure express route circuit Run the command terraform init for initializing the provider, Prepare your working directory for other commands Run the command terraform validate to Check whether the configuration is valid Run the command terraform plan Show changes required by

Assignment 1 HashiCorp Configuration Language HCL :Terraform requires infrastructure configuration files written in either HCL or JSON syntax. CDK for Terraform (CDKTF) works by translating configurations defined in an imperative programming language to JSON configuration files for Terraform. Terraform Core: This is the Terraform binary that communicates with plugins to manage infrastructure resources. It provides a common interface that allows you to leverage many different cloud providers, databases, services, and in-house solutions. Terraform Provider: Terraform Providers are behind the Terraform adage, provision any
