One thing, we also discussed allowing a request to include multiple
flavors. This could be used to mix-and-match pizza-base-flavors with
pizza-topping-flavors. So to escape the pizza metaphor briefly, you
could take XLarge VPS resources with a Medium SSD package and a Small
network package. This approach prevents too much resource fragmentation
and maintains a level of convenience for the user while allowing for an
exponential number of flavor combinations.
