Request from ci cost management working group: https://coreos.slack.com/archives/C02TYAMM5JP/p1661293177869409
I'm looking into reducing our overall Azure cost. Specifically, how we might decrease the cost by using Reserved VM Instances. I see we are using the DSv3 series for masters and workers. If we commit to using a given series for 1 year, we can save a significant percentage. But I'd like to make sure of a couple things before suggesting we do so.
- There is now a DSv5 series which costs around 5% less and benchmarks better than the DSv3. The major difference is that v5s don't have a temporary storage disk.
- Has Azure storage tech improved at all? Could we default to a non premium storage for worker nodes?
