Method and system for evaluating the resiliency of a distributed computing service by inducing latency

Techniques are disclosed for validating the resiliency of a networked application made available using a distributed computing infrastructure. In one embodiment, a latency monitoring application observes each active application component and at specified or 5 unspecified intervals, selects one and introduces latency or error messages in one or more messages emanating from the selected active application component. The latency monitoring application then measures the effect of the latency or error messages on other active application components that are dependent on the affected active application component. By observing the effects of the failed server on the rest of the network 10 application, a provider can ensure that each component can tolerate any unexpected latency or error conditions with the distributed computing infrastructure.
