* Change default controller_type to Standard_B2s. A B2s is cheaper by $17/month and provides 2 vCPU, 4GB RAM (vs 1 vCPU, 3.5GB RAM) * Change default worker_type to Standard_DS1_v2. F1 was the previous generation. The DS1_v2 is newer, similar cost, more memory, and still supports Low Priority mode, if desired
