It would have to be a zonal cluster, I think. A regional cluster would have 3 nodes, minimum (ish¹). (Unless maybe if you can do a two-zone regional cluster? But I'm not sure why you'd ever do that, though. I don't have much experience w/ the zonal ones, since typically we want our service spread across multiple failure domains. OP seems to be in the bootstrap phase, so the cost savings might be > the reliability at their present scale, to them, which I can respect.) ¹you can have a zero node regional cluster, but it isn't going to do much work.
