Meta-Arguments
These powerful features in Terraform allow you to dynamically manage multiple resources without duplicating code.

Count Meta-Argument:

• Perfect for creating multiple identical resources
• Simple numeric iteration
• Great for basic scaling needs

For_Each Meta-Argument:

• More flexible than count
• Works with maps and sets
• Better for resources with unique configurations

count: Create multiple identical resources efficiently.
for_each: Iterate over sets or maps to create resources with unique properties.

Use

• Reduce code duplication.
• Scale resources dynamically.
• Customize resource configurations effortlessly.

Lifecycles: Understand how you can fine-tune resource behavior in Terraform (like preventing destruction or recreating resources when needed).

Meta-Arguments: Dive into count, and for_each to handle resource dependencies, scaling, and loops more efficiently.

Data Sources: Want to reuse information from your cloud environment without re-creating it? Data sources make it possible, saving time and avoiding duplication.
