It's worth pointing out that nested virtualization is a thing these days, and some providers might even support it! That means you could buy one large instance and sub-divide it yourself into multiple VMs if you want to.
In practice, unless you need that flexibility to dynamically spin the VMs up and down with various specs AND don't want to or cannot use a provider's API for that, I'm not sure why you'd want to if you didn't have to for some crazy reason.
Except for the problem that you pay a premium for larger vm's. you can't compete with t instances on aws, for starters. Mike
