edited for style and clarity. take or leave especially if I've introduced any inconsistencies.

let me know if you have any questions.

[jloleysens]

Thanks for the very useful guidance @shainaraskas , I think I've addressed all of your points. Let me know what you think!

[shainaraskas]

a couple of little formatting things, along with a couple of small clarifications. looking really good + almost ready

[rudolf]

Left some nits to use terminology slightly closer to the Cloud configuration UI

[jloleysens]

Thanks @rudolf and @shainaraskas for the feedback, I think I've addressed all of it. Let me know what you think!

[shainaraskas]

couple little bits of feedback for polish. approving to unblock, but I suggest at least altering the heading levels in "Advanced scaling using stack monitoring metrics" before shipping.

[shainaraskas]

I suggest moving this down after the "advanced" case because the first sentence of the "advanced" case is "building on the simple strategy ..." so the flow is kind of broken

to make it visible, you could xref it from the two scaling approach sections, like "After you determine the necessary sizing for {{kib}}, change its allocated resources."
