terraform + AWS

Discover the advantages of Terraform: a simple, easy-to-learn tool with global cloud providers, ideal for creating infrastructure, not for configuring software inside virtual machines.

Learn how Terraform uses a single language to create infrastructure across cloud vendors, just by changing the provider and resource configuration, and why it's simpler than native tools.

Explore why terraform beats api or cli usage by preserving state, preventing duplicate resources on repeated runs, demonstrated with a simple VPC example.

Explore the root module as the folder that holds configuration, variables, and outputs. See how main.tf defines the provider and a basic resource, with variable and output blocks explained.

Learn how to run a terraform configuration to create a VPC on AWS by using init, plan, and apply, including provider download and the .terraform directory.

Learn the heshy configuration language (fcl) with arguments and blocks, and see how provider, variable, resource, data, and output blocks compose a Terraform configuration.

Explore Terraform collection types by creating lists, sets, and maps, comparing list indexing, value searches, and outputs, and learn how quotes affect string values in Terraform.

Learn to create objects with a defined schema in Terraform and build maps of these objects to store non-primitive values like block and region, then output and verify results.

Explain how data blocks and data sources pull existing configuration data, such as a VPC, to provision a virtual machine, and reveal outputs via data attributes.
