The most important element is to secure connectivity to target assets and line of business systems subject to monitoring and integration. The on-premises software gateway could run on a lightweight Linux(pref Ubuntu 16.4 or later) or Windows (pref. 10 or Server 2016) machines, depending on the requirements of the monitored equipment. The on-premises gateway shall have connectivity to the Internet to push telemetry to the cloud. Finally, yet importantly, a Microsoft Azure cloud subscription for the underlying platform backend can be provided by the integrator, if such is not present (est. cost. 120EUR/month for 10-20 monitored devices and 160EUR/month for 40). Depending on specific requirements some additional services may be required (i.e. subscription to an SMS capable service, external sensors or additional hardware).
