  Terraform creates andmanages resources on cloud platforms and other services through their application programming Interfaces (APIs). Providers enable Terraform to work with virtually any platform or service with an accessible API.

  Write Define infrastructure in configurationfiles Plan Review the changes Terraform will make to your infrastructure Apply Terraform provisions your infrastructure and updates the state files 1000+ PROVIDERS Write Terraform configuration files define the infrastructure resources to be created or managed with Terraform. Plan The "terraform plan" command lets you see how Terraform will modify your infrastructure after it is initialized. Apply With "terraform apply", you can apply the changes to your infrastructure once the plan has been reviewed and approved.

  terraform init Main TerraformCommands It downloads and installs any necessary plugins and modules to initialize a Terraform working directory. terraform plan terraform apply terraform validate terraform destroy > > > > > This command, generates an execution plan showing what will happen when you apply your configuration. In other words, it is a preview of the changes to your infrastructure without having to make them. It applies the changes to an infrastructure. Depending on the desired state, resources are created, updated, or deleted. It validates the terraform configuration files to check for any syntax errors. This command, destroys the infrastructure resources managed by terraform.

  Terraform Benefits • Cloudplatform agnostic • Agentless • Ease deployment • Cost Estimation It doesn’t require additional software. Nothing is needed to install. The agentless approach in Terraform simplifies the infrastructure management process, increases flexibility, improves security, and reduces costs. Being agnostic cloud platform terraform means it can be used to manage infrastructure resources across multiple cloud providers, such as Microsoft Azure, Google Cloud, AWS, and others. Organizations can deploy infrastructure resources faster, more efficiently, and consistently while reducing errors and automating infrastructure deployments. The cost estimation benefits of Terraform can help organizations better manage their infrastructure spending, create more accurate budgets, optimize resource usage, and choose the most cost-effective cloud provider for their needs.

  Terraform Terminology Resource: Resourcesare the most important element in the Terraform language. Each resource block describes one or more infrastructure objects, such as virtual networks, compute instances, or higher-level components such as DNS records. Provider: A plugin that defines the APIs and resources available for a specific cloud platform or service. For Azure, the provider is the "azurerm" provider. Module: Modules are containers for multiple resources that are used together. A module consists of a collection of .tf and/or .tf.json files kept together in a directory. Input variable: Input variables let you customize aspects of Terraform modules without altering the module's own source code. Output variable: Output values make information about your infrastructure available on the command line and can expose information for other Terraform configurations to use. Output values are similar to return values in programming languages. Data Source: Data sources allow Terraform to use information defined outside of Terraform, defined by another separate Terraform configuration, or modified by functions. State: Terraform must store state about your managed infrastructure and configuration. This state is used by Terraform to map real world resources to your configuration, keep track of metadata, and to improve performance for large infrastructures. This state is stored by default in a local file named "terraform.
