1. A system comprising: a plurality of server machines, each comprising at least one computer processor, one or more computer memories, and an input-output bus; a data store storing corresponding load and health measurements of the plurality of server machines; a neural network configured to receive the corresponding load and health measurements as inputs; a memory of a computing device storing a learn module that, when executed by a processor of the computing device, causes an update to the neural network using inputs of corresponding load and health measurements of the plurality of server machines; the memory of the computing device storing a predictor module that, when executed by the processor of the computing device, generates a predicted health value of the plurality of server machines, using the updated neural network, given a hypothetical increased load value, wherein the predicted health value comprises a confidence score; and the memory of the computing device storing a simulator module that, when executed by the processor of the computing device, generates a simulated load on the plurality of server machines in accordance with hypothetical increased load value.
