Course Outline
Infrastructure-as-Code Sovereignty
- Recognizing the risks associated with cloud consoles and SaaS IaC, such as vendor lock-in and audit deficiencies.
- Exploring Terraform architecture in depth: core components, providers, state management, and the plan/apply workflow.
- Conducting a comparative analysis of Terraform versus alternatives like Pulumi, Ansible, and CloudFormation.
