What is Infrastructure as Code (IaC)?

In the rapidly evolving world of IT and software development, Infrastructure as Code (IaC) has emerged as a game-changing concept.
It simplifies and automates the management of infrastructure, making deployment faster, more reliable, and consistent. With the increasing adoption of cloud platforms, IaC has become a cornerstone in modern DevOps practices.
If you are considering a career in cloud technologies or DevOps, understanding IaC is crucial. Whether you're exploring Cloud Computing classes in Bangalore or diving deep into a Cloud Computing course in Bangalore, IaC will undoubtedly be part of your learning journey. Let’s explore what IaC is,how it works, and why it's so important in the world of cloud computing.

Understanding Infrastructure as Code (IaC)
Infrastructure as Code refers to the practice of managing and provisioning computing infrastructure using machine-readable configuration files,
rather than through manual hardware configuration or interactive configuration tools.
In simpler terms, IaC allows IT teams to write code that defines the infrastructure they need — from virtual machines and storage to networks
and services — and then deploy that infrastructure automatically.
Instead of clicking around in a cloud provider’s UI or executing manual commands, engineers write scripts or use declarative language (like YAML or JSON) to define what the environment should look like.

Why Is IaC Important?
The traditional way of managing infrastructure was manual, error-prone, and time-consuming. Imagine having to manually configure servers,
set up databases, or tweak network settings every time you launch an application. This approach doesn’t scale well, especially in large
organizations or agile environments.How IaC Works with Cloud Computing
IaC is tightly integrated with cloud computing. Public cloud platforms like AWS, Azure, and Google Cloud offer APIs that IaC tools can interact with to provision and manage resources.
When deploying infrastructure on the cloud using IaC:
You define your infrastructure in a code file.
That file is executed by an IaC tool.
The tool interacts with the cloud provider’s API to create the necessary resources.
The entire infrastructure setup becomes repeatable and version-controlled.
