Load balancing is critical to the maintenance of any highly demand digital experiences, website, application, databases, other compute resources. Proper utilization of a load balancer can prevent application failure, improve performance and availability by disturbing traffic.
In this lightboard video, Bradley Knapp with IBM explains how load balancers work and some different traffic distribution model options.

    Really nice video. In my point of view, it could be pretty good to add labels to 1, 2 and 3 scenarios to better remember the classification. Also maybe good to explain why the random method could be fine according to math. It's not clear. Maybe the random method is not so simple and gets one of the servers which is loaded less than the average? :-) Absolute random approach is worse than rolling-robin in my vision.

    Mustafa, the idea of a load balancer is that its only purpose is to distribute the number of active sessions among N number of servers that are supporting the workload for X number of clients. The load balancer itself is only used at the beginning of the session, it's not a constant intermediary point - its job is to assign the session to the least active backend server, and then to await the next session that needs to be instantiated. Now, that said, it is always best practice to size your load balancer deployment the same way that you would size your server deployment - you will need much higher performance for load balancers that can expect 5,000 simultaneous instantiations than you would for a workload that would only ever see 500 instantiations, for example.

IBM Cloud offers several load balancing solutions, you can check them out here 👉 ibm.co/3n3Rz7l Additionally, a variety of open source load balancers are available, each with different functionality and server compatibility: Neutrino, Gobetween, LoadMaster by Kemp, and the Linux-based Seesaw. LoadMaster and Neutrino offer free versions and fee-based commercial versions with added functionality. If you’re considering open source, be sure to review functionality and compatibility with your specific server first. 🙂
