HashiCorp Terraform

1280px Terraform Logo.svg removebg preview 1

Terraform is an open-source, cloud-agnostic tool that helps users build, change, and version infrastructure. It’s used primarily by DevOps teams to automate infrastructure tasks, such as provisioning cloud resources. 

Terraform was created by HashiCorp in 2014. It’s written in the Go language. Users define and provide data center infrastructure using a declarative configuration language known as HashiCorp Configuration Language (HCL), or optionally JSON. 

Benefits of Terrafrom:-

  • CollaborationTeams: can define and manage infrastructure using version control, which makes it easier for multiple people to collaborate and work on the same codebase. 
  • Full-stack deployment: You can have Amazon instances running Kubernetes containers with your workloads and manage the whole system from one tool. 
  • Management of external resources: Terraform manages external resources (network appliances, software as a service, platform as a service, etc.) with “providers”. 
  • Tracking resource changes: Terraform’s state allows you to track resource changes throughout your deployments. 
  • Reducing the amount of code: You can create a module and reference it multiple times, passing different parameters. 
  • Drift detection: The drift detection feature in Terraform Cloud is designed to identify and manage configuration drift in your infrastructure deployments. 
  • Security practices and governance: With Terraform Cloud, you get Sentinel and OPA policies to enforce security practices and governance throughout your workflow

Why Terraform?

Think of Terraform as a magical blueprint for building and managing the infrastructure that supports your software applications. Here’s why DevOps engineers need Terraform in simple terms

  • Infrastructure Wizardry: Terraform is like a wizard’s spellbook for creating and managing servers, databases, and other infrastructure components. It allows DevOps engineers to describe their desired infrastructure in a simple, human-readable language.
  • Consistency Enforcer: Just as a recipe ensures that you make the same delicious dish every time, Terraform ensures that your infrastructure is consistent. It creates and configures resources exactly as you specify, reducing errors and surprises.
  • Efficiency Booster: Terraform automates the process of creating, modifying, and destroying infrastructure. It’s like having an army of helpers who can set up servers and services in minutes instead of hours or days.
  • Multi-Cloud Harmony: Terraform is cloud-agnostic, meaning it works with different cloud providers like AWS, Azure, and Google Cloud. It lets DevOps engineers manage infrastructure across multiple clouds with a single set of commands.
  • Version Control Friend: Just as you save different versions of your document, Terraform lets you version-control your infrastructure. This means you can track changes over time and easily roll back to previous onfigurations if needed.
  • Collaboration Facilitator: Terraform enables teamwork. Multiple DevOps engineers can work on the same infrastructure code, and Terraform helps merge their changes and maintain consistency.
  • Risk Minimizer: Like a safety net, Terraform can help recover from disasters. If something goes wrong, you can use your Terraform code to rebuild your infrastructure exactly as it was before.
  • Security Sentinel: Terraform helps ensure that your infrastructure is configured securely. It can enforce security policies and best practices, reducing vulnerabilities. It makes sure everything is built correctly, saves time, and keeps everything organized and consistent, whether you’re working in one cloud or many.

HashiCorp Packer


Packer is an open-source tool made by Hashicorp. It automates the process of creating virtual machine images on the cloud and on-prem virtualized environments. Packer uses a single JSON config file to create identical machine images for multiple platforms.

Packer can be used to: 

  • Create virtual machine images on the cloud and on-prem virtualized environments
  • Create identical machine images for multiple platforms
  • Create custom images in Windows or Linux
  • Create azure arm templates

Benefits of Packer:

  • Fast infrastructure deployment: Packer images allow users to launch provisioned and configured machines in seconds.
  • Greater testability: Users can quickly launch and test machine images to verify that they are working.
  • Terraform interoperability: Users can standardize image workflows across cloud providers.
  • VM creation automation: Packer creates consistent images for multiple platforms in parallel.
  • Improved stability: Packer installs and configures all software for a machine at the time the image is built.
