This report reflects on the best way to implement a software component which defines the balancer module, that is a specific module meant to spread the traffic a web-platform receives over multiple back-end servers. In particular, the discussion will be centered on which load-balancing algorithm and tool is the best by the point of view of a high-demand throughput system in order to avoid the overload of some compute nodes, considering that many open-source load-balancers can be found in the market in a great variety of forms, implementations and features; the focus will be over the needs of a Demand Side Platform, where performances are put at first place and the internals of the platform itself change constantly (such as the number of servers and the addresses of the servers itself).
