2GB

probably not a lot of cache

that would not be enough to serve very many clients

scratching that idea then.

I run normal nodes on 2GB VPS fine, but for public RPC node it would not be ideal

Right. I already have a dockerized one for personal use, but want to set up a public one.

Still seems remote nodes are important due to the "entrance cost" of downloading and synching 100GB blockchain for new users.

yeah thats why bootstrap exists with the temporary remote node usage while your own syncs up
