1. Overview

This document provides the necessary information for configuring RCDevs Cloud services on WebADM v2.x. This document is not applicable for WebADM 1.x versions.

What is RCDevs Cloud Services ?

RCDevs Cloud Services are hosted by RCDevs Security SA, providing additional capabilities for OpenOTP and SpanKey, examples of cloud based functionality are:

  • Push Login/Signature
  • Cloud licenses
  • Cloud backup

The connection from the local WebADM server to the RCDevs Cloud is based on HTTP2 protocol, and can be transported through a proxy server between WebADM servers and RCDevs Cloud infrastructure. The unique endpoint for all services (push, licenses…) is https://cloud.rcdevs.com. Your WebADM server(s) must be allowed to reach https://cloud.rcdevs.com port 443 in order to use RCDevs Cloud Services.

Please note that this document is not a guide for installing WebADM or its applications (Web Services and WebApps). Specific application guides are available in RCDevs Online Documentation. WebADM use or administration is not covered by this guide and is documented in the RCDevs WebADM Administrator Guide. In this guide, we will consider a common installation scenario where WebADM v2.x is running in cluster mode with two active servers.
