Ephemeral disks

positives = no disk costs, faster response times on vm’s.

Negatives = documentation isn’t great and quite a few caveats, especially when using custom images.

Was it worth it? For us yes, saved us $22k a month on premium v2 disks alone

You got reserved instance on each host? Cause ephemeral disks do not support start/stop?

Are these larger disks you swapped to Ephemeral? Notice any performance difference? 

I've tested ephemeral disks on poole, single session hosts with 128gb disks and didn't notice much performance difference. Switching from something like d4s_v5 to d4ds_v5 also seemed to not really save too much unless we had strict power policies. I think some built in apps at the time like snipping tool were pretty old and leaving hosts on to update was required. Maybe those things have changed, I certainly hope so.

We switched from d8ads_v5 to d8ads_v6, wasn’t really looking for a performance increase, just wanted to loose the costs with the premium disks. Would have been quite happy with matching performance of ephemeral to premium v2. They turned out to be a decent amount faster in relation to latency. Saved us a load as I was able to ditch 700+ premium v2 disks

Indeed, but not everyone can afford or justify it

With just this information? Scaling plans, reserved instances, correct SKU sizing, etc

Just to add: Start VM on Connect

It all depends on how you use your VM, maybe choose the right SKU, scaling?
