Cloud-native technologies have pushed the traditional infrastructure management to the edge of obsolescence. Enter IaC, a revolutionary DevOps technique that automates provisioning and managing infrastructure using code.

This article will explore the core concepts of IaC, including tools, benefits and real-world examples. Consider taking a DevOps class in Pune, or a DevOps class in Pune.

What is Infrastructure as Code (IAC)? Infrastructure As Code (IaC). is a process for managing and provisioning infrastructure, such as networks, virtual machines and databases, using machine-readable scripts rather than manual processes.

Developers and DevOps can:

Spin up consistent environments

Automate scaling

Prevent configuration drift

Setups for version control infrastructure

IaC is a framework that treats infrastructure in the same manner as developers do code.

How IaC works in a DevOps pipeline In a typical DevOps cycle:

Developers define infrastructures with code (e.g. YAML, JSON or HCL).

The code is then committed to a version-control system (like Git).

Terraform and Ansible are two tools that trigger the provisioning process when used with CI/CD.

Cloud resources are automatically and consistently spun up.

In trainings in Pune, IaC is taught as part of the curriculum to help students better understand these integrations.

Benefits of Infrastructure-as-Code Consistency

Replicating environments precisely will prevent "works on my computer" issues.

Speed

Provide complete environments in minutes, not hours or days.

Cost-Effective

Automatically tear down any unused infrastructure in order to save money.

Version Control

Track infrastructure changes just as you would source code.

Testing

Validate infrastructure using automated testing suites before deployment.

You can start by enrolling in DevOps classes in Pune

Real-World Usecase: Automating a Multitier Web App Consider deploying a three-tier application that:

Web layer

Application logic layer

Database layer

Terraform, Ansible and other IaC tools:

Define your entire infrastructure as code

Securely store secrets with Vault and AWS Secrets manager

Configure automatically networking, firewalls and SSL

Consistently deploy across development, staging and production

You can learn DevOps in Pune to build this type of setup, which is used by many industries, including healthcare, financial, and SaaS.

Declarative vs. Imperative IaC There are two main approaches:

Types of Description You can also find out more about Declarative Define and what should the final state look like Terraform and CloudFormation Imperative Define and how you can get to your desired state Shell scripts Ansible

Declarative is preferred for large environments because of its predictability.

IaC and DevOps Automation DevOps Automation is tightly integrated with Infrastructure as code.

IaC scripts are triggered by CI/CD pipelines using tools such as Jenkins or GitLab.

Test environments are always available with dynamic provisioning

Continuous Monitoring Tools ensure compliance and rollback if needed
