What you get

Paid — ~$31-32/month (performance-1x, 2GB). Dedicated-CPU micro-VM: performance-1x 2GB ~$0.0000120/s (~$31/mo always-on, ~$0.0431/hr); extra RAM ~$5/GB/month. Per-second billing, scale-to-zero when stopped.

A dedicated vCPU + 2GB always-on for ~$31/mo; per-second billing means intermittent workloads cost a fraction. Good value for consistent-performance a
