There are ways to scale the performance of SignalR vertically on a single box—for example, adding more memory (scaling up)—and it's also possible to scale SignalR horizontally by adding more servers (scaling out) and making them exchange messages so that broadcasting is correctly replicated. Clients must be able to keep on working as usual, regardless of the actual physical endpoint they connect to and unaware of the changes in the infrastructure.
