[one-users] Communication Protocols with external Cloud Services

[Ruben S. Montero]

Hi

External cloud services uses http or https to communicate with the
users. This is the untrusted communication part. The internal cloud
service to core communications usually happens in the same machine or
in a trusted network (it is roughly the same pattern as CLI to core
communications) through XML-RPC.

Cheers

Ruben
