Questions tagged [signalr-backplane]

In electronics, a backplane is a group of parallel connectors. By analogy, a SignalR backplane connects multiple servers.

SignalR currently provides three backplanes for scale out purposes:

Windows Azure Service Bus: Service Bus is a messaging infrastructure that allows components to send messages in a loosely coupled way.

Redis: Redis is an in-memory key-value store. Redis supports a publish/subscribe (“pub/sub”) pattern for sending messages.

SQL Server: The SQL Server backplane writes messages to SQL tables. The backplane uses Service Broker for efficient messaging. However, it also works if Service Broker is not enabled.
