Description

Instead of 0 (unlimited) we could start with values that are reasonable for a normal size production cluster / typical cloud account.

MaxConcurrentInstanceCreateOps was invented to accommodate Azure limitations, but now that we have it, we might as well promote using it as a guard rail for all cloud providers.

Perhaps 10 ops per second and 1 concurrent create op. Recommend raising to 20 concurrent create ops for Azure since it doesn't return the "create" response until the instance has booted.

The two comments on MaxConcurrentInstanceCreateOps read a bit strange. Perhaps the "recommended by Azure" & azure docs link should move to the 2nd paragraph and the "can be used with other cloud providers too, if desired" bit in the first paragraph can be removed entirely?

The old comment says "node creation", while we're here I think it would be more consistent to change that to "instance creation".

Besides that, LGTM

I know Tom took the review but I saw the commit message go past and I looked at it.

The comments don't really explain the difference/relationship between MaxCloudOpsPerSecond and MaxConcurrentInstanceCreateOps.

I've addressed both reviewers' comments in eb29c5471bdface71362af6f4e6a669d0da8d346 on branch 18113-change-cloudops-defaults. Does that look better?

Yes, I think that addresses all concerns. LGTM.
