📄️ Round Robin
Round Robin is the most common, simple and, simultaneously, the most frequently used routing method for Traffic Distributor. It navigates request to backends in rotation, according to the specified server’s weights, which provides high availability of the distributed application and allows to easily leverage server’s load.
📄️ Sticky Sessions
This method is used to achieve server-affinity by sticking user to a particular backend, which allows to work with just one application version. Herewith, on the first visit, customer is routed based on the servers' weights, while assigned backend is remembered, ensuring that all subsequent requests from this user go to the same environment.
📄️ Failover
Failover is a special routing method, that implements project protection through keeping a fully functional environment copy in reserve. In other words, you have primary server and backup one - all the requests are initially forwarded to the first backend, while the second one is kept on a standby and is used only in case the primary service goes down.
