When should Terraform modules be used?

Terraform modules should be used for:

• Code reuse: Creating abstractions for frequently used configurations, such as VPCs, databases, or Kubernetes clusters.
• Code organization: Breaking down complex infrastructure into manageable, easily understandable parts.
• Collaboration: Allowing different teams to work on separate parts of the infrastructure without affecting each other.
• Configuration standardization: Ensuring consistency when deploying similar resources.
• Reducing duplication: Eliminating repetitive resource and data blocks.

Using modules enhances the readability, maintainability, and scalability of Terraform configurations.
