Infrastructure as code (IaC) Tools

Infrastructure as Code (IaC) is a big deal in the DevOps world today. It’s everywhere in the industry and has become a must-know skill for modern engineering roles.

With IaC, you write code to define the infrastructure you need for your project, just like you write code for the application itself. This code gets stored in version control, making it easy to track changes and work as a team.

For example, if you’re building a web app, IaC lets you define where it’s hosted—on platforms like Azure, AWS, or Google Cloud—and the specific service it uses, like an Azure Web App or an AWS S3 bucket. You can also set things like CPU, memory, security rules, and domain settings. This approach makes deployments faster, easier to repeat, and less prone to mistakes.

Terraform

Source: What is Terraform?

Terraform, created by HashiCorp, is a popular tool for managing infrastructure using code. It helps you set up and manage resources both on-premises and in the cloud. Thanks to its plugin-based design, you can easily extend Terraform to work with different platforms and handle complex setups across multiple cloud providers while staying compliant.

One of Terraform’s strengths is how it lets you package and reuse configurations as modules. This makes it simple to share and apply the same setup across projects, saving time and keeping things consistent.

Key Features

  • Multi-Cloud Support: Seamlessly manages resources in AWS, Azure, Google Cloud, and other providers.
  • State Management: Tracks infrastructure state to ensure predictable deployments.

AWS CloudFormation

Source: AWS CloudFormation

AWS CloudFormation is an AWS-native service that simplifies managing your cloud infrastructure. Unlike Terraform, which is multi-cloud, CloudFormation is specifically designed for AWS environments. You define your resources, such as EC2 instances or RDS databases, in a template, and CloudFormation takes care of provisioning and configuring them. It also handles resource dependencies, so you don’t have to manage them manually, making it an efficient option for AWS-only setups.

Key Features of AWS CloudFormation

  • Infrastructure as Code: Use declarative templates to define AWS resources.
  • Stack Management: Group resources into stacks for easier handling.
  • Automated Rollbacks: Revert failed deployments automatically to maintain stability.

AWS CloudFormation automates resource provisioning in AWS.

Example: Creating an AWS S3 Bucket

This YAML file defines an S3 bucket with versioning, access controls, and tags. You can deploy it using the AWS CLI or Management Console to create and manage your stack.

OpenTofu: An Open-Source Terraform Alternative

OpenTofu was created in response to HashiCorp’s decision to change Terraform’s licensing model, moving it away from a fully open-source framework. As a community-driven solution, OpenTofu ensures that DevOps teams can continue leveraging robust Infrastructure as Code (IaC) capabilities under a truly open-source license, free from vendor lock-in. It maintains compatibility with Terraform’s core features while fostering innovation and inclusivity.

Continuous Integration/Continuous Delivery & Deployment Tools

Continuous Integration (CI) ensures that code changes are frequently merged into a shared repository and automatically tested. When developers push changes, the application is built and tested to verify that new code doesn’t disrupt existing functionality. These tests typically include unit tests for individual components and integration tests to check how modules interact. By catching conflicts and bugs early, CI saves time and speeds up development.

Continuous Delivery (CD) builds on CI by automating the process of delivering tested code to staging or development environments. This ensures a consistent, reliable pipeline for preparing code for production.

Continuous Deployment takes automation a step further by automatically deploying successfully tested changes to production, enabling frequent and seamless updates to live environments.

Popular tools like ArgoCD, GitHub Actions, Helm, and Jenkins play a key role in implementing these practices, making the CI/CD process efficient and scalable.

ArgoCD
