Web Provider
The Web Provider interprets the requests received and sends the calculation requests to the Render Units. These are normally two dedicated machines with available resources in RAM and CPU. The second instance of WebProvider is provided to take over in case of downtime, especially if the front-end is a public website.
These machines must be connected to the renderers by LAN (local area network). Connection to the front-end server will be made by LAN or by WAN.
