You should always load balance your production application with at least two servers available to serve requests, so your application can stay online when a server restarts. At its simplest, load balancing is the act of making sure that all servers receive roughly the same number of requests over a given time period. A well-balanced application will be less likely to develop hot nodes that have stressed resource usage compared to other nodes. You can also add new servers to a well-balanced application to help reduce the load on all other servers in the cluster.

We’ll discuss the basics of load balancing before looking at how WebSockets can make achieving a well-balanced system more difficult than a traditional ...
