@Paul Bates Welcome to Microsoft Q&A, thank you for posting your here!
For your specific use case of running a simple Windows application on Azure for occasional configuration of a USB device using RDP from your iPad, you indeed don't need a high-powered virtual machine. You can opt for a more cost-effective and lower resource VM. Here are a few Azure VM options that would be suitable for your needs:
- Av2-Series VMs (A1_v2, A2_v2, A4_v2): These are basic VMs with lower processing power and memory. They are ideal for lightweight workloads and testing purposes. The A1 VM offers 1 virtual CPU and 1.75 GB of RAM, which should be sufficient for your occasional use.
- B-Series VMs (B1s, B2s, B4ms): The B-Series VMs are designed to offer burstable performance, which means they can provide higher CPU performance when needed and scale down during idle times. The B1s VM offers 1 virtual CPU and 1 GB of RAM, making it a good fit for your use case.
- D-Series VMs (D2s v3, D4s v3): If you want a bit more processing power, the D-Series VMs can be considered. The D2s v3 offers 2 virtual CPUs and 8 GB of RAM, which should be more than sufficient for your needs, and it still falls within a reasonable cost range.
