I have set up a VM on Azure as a small build server - nothing fancy yet, just being able to manually build LineageOS. I only spin it up when I need it, so when I do, I can assign quite a beefy machine and that's all fine. But: It needs a lot of hard drive space and the additional data disk needs to be paid 24/7, whether the VM is up or not. As such, it is eating up my (free MSDN) credits. I am not too well versed with Azure yet, so maybe there is a better way.

Does anybody know a cheap way to get a large-ish SSD on Azure? Maybe with ephemeral OS disks, potentially running on another (small) VM in the same network and sharing it?
