In this **Terraform Tutorial**, we’ll explore **Terraform Data Sources** and learn how to use them effectively in your projects. Data sources are a powerful feature in Terraform that let you **fetch and use existing information** from your cloud provider or environment instead of creating new resources every time. This makes your Infrastructure as Code (IaC) more flexible, reusable, and dynamic.
A data source allows you to query details about existing infrastructure — like AMIs, VPCs, or subnets in AWS — and then use that information to configure other resources. This is especially useful in real-world projects where you need to reference already deployed infrastructure without hardcoding values.
In this tutorial, we’ll cover:
* What Terraform Data Sources are and why they’re important
* How to declare and configure data sources in Terraform
* Real-world examples of using data sources with AWS (like fetching the latest AMI)
* Using data sources with variables and outputs
* The difference between resources and data sources in Terraform
* Best practices for organizing and managing data sources in projects
By the end of this video, you’ll know exactly how to use Terraform Data Sources to make your configurations more **modular, dynamic, and production-ready**. You’ll see how they help reduce errors, improve reusability, and integrate seamlessly with existing cloud infrastructure.
This tutorial is perfect for **Terraform beginners** and **DevOps engineers** who want to go be
