Hands-On Terraform: Build AWS Infrastructure with CLI
A technical tutorial demonstrating how to use Terraform (HashiCorp) on Ubuntu to initialize and manage AWS infrastructure via the CLI. The article covers the core Terraform workflow (terraform init, plan, apply, destroy), HCL file structure, a sample .tf that creates two S3 buckets in ap-southeast-1 (using aws provider ~> 6.0), inspecting and understanding terraform.tfstate (the state file), making in-place changes via plan/apply, and cleaning up resources with terraform destroy. It emphasizes best practices such as unique global S3 bucket names and never committing or manually editing state files.
Practical hands-on Terraform tutorial useful for engineers provisioning cloud infrastructure; educational but not industry-shifting.

Key Takeaways & Evidence Grounding
- Tutorial explains the core Terraform workflow: terraform init, terraform plan, terraform apply, terraform destroy.
- Provides a sample Terraform configuration that creates two AWS S3 buckets (names shown as examples) using provider "hashicorp/aws" version ~> 6.0 and region ap-southeast-1.
- Explains terraform.tfstate as Terraform's state file and warns against manual edits, deletion, or committing state to version control.
- Demonstrates making an in-place change (adding a tag) and shows the plan output indicating two resources will be changed, then applying and destroying resources to clean up.

Beginner Guide: Infrastructure as Code with Terraform
This tutorial introduces Infrastructure as Code (IaC) using Terraform. It explains the core IaC idea—describe infrastructure in version-controlled files—and why clicking in cloud consoles fails to scale. The article covers Terraform's four core concepts (provider, resource, variable, output), shows a simple AWS S3 example, and describes the plan → apply workflow (terraform init, plan, apply, destroy). It emphasizes Terraform state as the source of truth, warns against committing state or console edits, and recommends remote state backends with locking for teams. The guide is aimed at practitioners who have created cloud resources via consoles and want repeatable, reviewable infrastructure.
Terraform & CloudFormation: An IaC How‑To Journey
A first‑person technical walkthrough explaining why and how the author moved from manual console clicks to Infrastructure as Code (IaC) using Terraform and AWS CloudFormation. The article compares Terraform (cloud‑agnostic, HCL-based) and CloudFormation (AWS‑native, JSON/YAML), shows example implementations for provisioning an S3 static website (with recommended practices), and lists common pitfalls and fixes — e.g., avoiding hardcoded credentials, preferring bucket policies over ACLs, using remote state with locking for Terraform, and reviewing CloudFormation change sets. The author frames IaC benefits as reproducibility, version control, teamwork safety, and faster onboarding, and provides concrete code examples and operational best practices.
Demystifying Terraform: IaC Lessons from AWS Student Day
A recap of a presentation at AWS Student Community Day in Tirupati (Nov 1, 2025) where Senior Cloud Engineer and AWS Community Builder Keerthivasan Kannan explained Infrastructure as Code using Terraform. The session covered Terraform's core workflow (init, plan, apply, destroy), the importance of storing the state file in cloud storage, recommended file structure (providers.tf, variables.tf, locals.tf, output.tf), and best practices including modules, DRY principles, variable validation, count vs for_each, dynamic blocks, built-in functions and conditionals. The article was published on June 15, 2026 and aims to help students and cloud beginners apply Terraform to provision and manage cloud resources consistently and repeatably.
