Querying Data with Data Sources

In Terraform, we often need to reference existing infrastructure or external data that isn't managed by our current configuration.

This is where Data Sources come in! They allow your Terraform configuration to fetch information about resources that have already been provisioned or external services.

It's important to distinguish data sources from resources.

• Resources define infrastructure that Terraform will create, update, or delete.
• Data Sources only fetch information about existing infrastructure or data. They do not create or modify anything.

Think of them as read-only queries for your infrastructure.
