Abstract: The present disclosure relates to dynamically allocating multitier applications based upon performance and reliability of resources. A controller analyzes resources and applications hosted by the resources, and collects operational data relating to the applications and resources. The controller is configured to determine an allocation scheme for allocating or reallocating the applications upon failure of a resource and/or upon rollout or distribution of a new application. The controller generates configuration data that describes steps for implementing the allocation scheme. The resources are monitored, in some embodiments, by monitoring devices. The monitoring devices collect and report the operational information and generate alarms if resources fail.

Abstract: According to one method for detecting a hidden shared dependency through covert channels, a pattern of bursts is transmitted to a first application hosted by a first server. The pattern of bursts may be designed to stress a potential hidden dependency shared by the first application and a second application hosted by a second server. Each of the bursts may include one or more concurrent requests. Probe requests are transmitted to the second application. Responses corresponding to the probe requests are received from the second application. Response times are determined by computing a difference between times that the probe requests are transmitted and times that the corresponding responses are received. A determination is made whether the potential hidden dependency exists based on the response times.
