Can photon do what I need?

Options
Hi! I am trying to find a solution to my game. There are so many different services that photon provides, I kinda get overwhelmed. I have never done any proper web stuff so pardon me if my questions are stupid.

What I need:



My team used firebase and achieved it without too much trouble. But we are launching a new version in China and fireabse is out, so we are trying to find an alternative solution that would work in Mainland China. Our data is very light ( mostly just ints and occasionally a image uri) My questions are:

can photon do it ? (web-app as clients and unity as the "host")
what photon services do i need?

where should i get started?
