IaC concepts

Terraform is an open-source, declarative IaC tool that allows developers to define multi-cloud infrastructure using HashiCorp Configuration Language (HCL). It is not a configuration management tool like Ansible, which focuses on installing and managing software on existing servers rather than provisioning the underlying infrastructure.

Infrastructure as Code (IaC) allows teams to automatically manage, provision, and version infrastructure through configuration files rather than manual processes. Manual cloud configuration is incorrect because it is error-prone, hard to scale, and lacks the version control benefits that define true IaC workflows.
