## What is Infrastructure as Code?
26+
27+
[Infrastructure as Code (IaC)](/what-is/what-is-infrastructure-as-code/) is an approach to automating the provisioning and management of infrastructure using software engineering principles, approaches, and tools. Rather than manually configuring servers, networks, and cloud resources through user interfaces or command-line tools, IaC enables you to define your entire infrastructure declaratively through code.
28+
29+
This approach brings the same benefits that have revolutionized software development—version control, automated testing, code reviews, and CI/CD pipelines—to infrastructure management.
30+
31+
## What Are Infrastructure as Code Tools?
32+
33+
Infrastructure as Code tools are platforms and frameworks that enable you to define, provision, and manage infrastructure resources through code rather than manual processes. These tools translate your infrastructure definitions into API calls that create, modify, or destroy cloud resources across various providers.
34+
35+
The most effective IaC tools share several key characteristics:
36+
- **Declarative syntax**: Describe what you want, not how to achieve it
37+
- **Multi-cloud support**: Work across different cloud providers and services
38+
- **State management**: Track the current state of your infrastructure
39+
- **Preview capabilities**: Show what changes will be made before applying them
40+
- **Idempotency**: Safe to run multiple times with consistent results
41+
42+
## Why Use Infrastructure as Code Tools?
43+
44+
Modern organizations rely on IaC tools for several critical reasons:
45+
46+
**Consistency and Repeatability**: Deploy identical infrastructure across development, staging, and production environments, eliminating "works on my machine" problems for infrastructure.
47+
48+
**Speed and Efficiency**: Provision complex multi-cloud infrastructures in minutes rather than hours or days of manual work.
49+
50+
**Collaboration and Governance**: Enable teams to work together on infrastructure changes through code reviews, version control, and automated testing.
51+
52+
**Cost Management**: Automatically provision and deprovision resources as needed, preventing resource sprawl and unexpected cloud bills.
53+
54+
**Compliance and Security**: Enforce consistent security policies and compliance requirements across all infrastructure deployments.
55+
56+
**Disaster Recovery**: Quickly recreate entire infrastructures from code in case of outages or data center failures.
57+
58+
