The Paradigm Shift to Code-Provisioned Clusters and Pods
summary
Demonstrates moving cluster and pod provisioning from consoles into code using tools like Terraform, Pulumi, OpenTofu, and the AWS CDK (TypeScript/Python/Java/.NET), plus GitHub Actions and LocalStack for pipelines and local testing. Shows CDK generating YAML via cdk synth, achieving idempotent deployments and pipelines-as-code, and handles a concrete example of programmatically provisioning 100 instances with conditional types (odd vs even).
