We have not tested any specific cloud hosting platform but are aware that there are customers that have had success hosting with Azure. However, as long as the requirements below are met, using any cloud hosting platform should be possible.
The NetworkRepeater is installed on any standard Windows installation, so as long as the network traffic needed is allowed then hosting it on any cloud hosting platform that allows you to set up and configure your own Windows server should be possible.
Note that the NetworkRepeater needs to be able to send UDP broadcasts in the same local network as the Operators that are intended to listen to it are in, and needs to be able to receive UDP unicasts from them. It additionally needs to be allowed to set up remote TCP connections to remote Mimer Network Interfaces or Mimer RadioServers.
Due to a known limitation in Azure where UDP broadcasts are not allowed between hosts we have added support in the NetworkRepeater to configure a list of hosts to send UDP unicasts to instead of using any UDP broadcasts.
