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.
Popular IaC Tools That You Should Know
You can also use the following tool: Purpose The Language of the Speaker
Terraform Cloud-agnostic Provisioning HCL
AWS CloudFormation Setup of AWS native infrastructure JSON/YAML
Ansible Configuration management YAML
Pulumi IaC using general-purpose languages TypeScript and Python
Chef Declarative Automation for Configurations Ruby DSL

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
