We are solving our problems with upsolving in real time! Our team uses it as an API gateway (our own).
It's very good because we can solve all issues related to security or network performance without having any knowledge about how these things work internally. I don't like anything so far - everything works fine but i would really love if they have some way where you could see your logs easily when something goes wrong inside this service. You should try them out once before deciding whether yo need their services or not :) Data synchronization between different sources/clouds has become much easier now than ever thanks to upsolvers!
