With Terraform, you can clearly see several benefits, including:
-
Automation: Terraform automates the process of provisioning and managing infrastructure, reducing the risk of human error and increasing efficiency.

Efficiency: Terraform reduces the time and effort required to manage infrastructure, allowing you to focus on higher-level tasks and increasing overall efficiency.
-
Cost-Effective: Terraform helps reduce costs by allowing you to manage infrastructure resources more efficiently, reducing waste, and optimizing resource utilization.
