Hello, Most drivers will handle the load balancing for you and provide policies for configuring your desired approach for load balancing, i.e. load balance around the entire ring or localize around a specific DC. Your clients will leverage the driver for connections so that the client machines do not simply select one node for data and coordination.
Check out DataStax's driver's documentation on load balancing for more information. [1] Other drivers, like Astyan [2] provide similar capabilities as well.
