Oscar Medina, a senior cloud architect at Amazon Web Services, demonstrated a collaborative workflow for platform and developer teams using CDK for Terraform, Terraform Cloud, and Sentinel to safely deploy EKS workloads to AWS. The workflow enables self-service Amazon EKS deployments for developers while ensuring that essential guardrails remain in place. It leverages several tools and platforms, including Amazon EKS, CDK for Terraform, Terraform Cloud, and Sentinel policies. This approach allows platform teams to manage costs by preventing users from deploying services of the LoadBalancer type, while developer teams can use TypeScript to define infrastructure configurations.
