What is a primary benefit of using modules in Terraform?

The use of modules in Terraform primarily encourages code reuse and organization. Modules are a way to encapsulate and group related resources that can be managed as a single unit. This modular approach allows you to define infrastructure components once and reuse them multiple times within your configurations. By organizing your infrastructure into modules, you can achieve better maintainability and clarity in your code.

When you create a module, you can not only reuse the same code across different environments (like development, staging, and production) but also share it with other projects or teams, enhancing collaboration and efficiency. Additionally, modules help in decluttering your main configuration files, allowing teams to focus on high-level resources while delegating specific implementations to the modules.

While modules can also indirectly impact aspects like state management and dependency resolution, their core advantage lies in fostering an organized and reusable code structure, making complex infrastructure setups more manageable and scalable.
