External API's: Next.js server actions or Convex actions?
1. For server actions, should I use them via Next.js server actions, or create them as Convex actions. In this case I'm talking about interfacing with external services/api's. I'm using some purely server side, and some in client as well (that do not store anything in the database). Can it be answered like "when needing to query/mutate data in the database use Convex otherwise Next.js" or is it as simple as "do anything backend related in Convex"?

2. how does Convex's compute (convex runtime and node) compare to Vercel's fluid compute, in terms of cost and speed?
3. I'm servicing customers world wide, should I also care about the location of where these functions are executed, for this Vercel (currently) has better options available.
