Bootstrapping the SDAF Control Plane & Deployer VM Tooling Part 2: Hardening the Execution Runner, Dynamic UAMI Governance, and Zero-Exposure Bastion Operations 1. The Role of the Control Plane: Beyond "Run from My Laptop" In small-scale cloud proof-of-concepts, engineers frequently run Terraform commands and Ansible playbooks directly from their local laptops or through generic CI/CD runners. While this approach suffices for stateless web services or short-lived microservices, it is an anti-pattern for enterprise SAP deployments.

You give Microsoft’s SAP Deployment Automation Framework (SDAF) an empty Azure subscription, run a script, and watch it deploy a clean hub-and-spoke virtual network, subnets, route tables, network security groups (NSGs), Key Vaults, and compute nodes tailored strictly to SAP best practices. However, in large enterprise environments—such as telecommunications, banking, and global conglomerates—cloud infrastructure rarely begins with a blank canvas. Before the SAP basis or automation engineers even receive access, a cloud platform team or third-party vendor has typically already provisioned a centralized Enterprise Azure Landing Zone (ALZ) . This landing zone comes with rigid corporate ...
