POD-Diagnosis: Error Diagnosis of Sporadic Operations on Cloud Applications

Applications in the cloud are subject to sporadic changes due to operational activities such as upgrade, redeployment, and on-demand scaling. These operations are also subject to interferences from other simultaneous operations. Increasing the dependability of these sporadic operations is non-trivial, particularly since traditional anomaly-detection-based diagnosis techniques are less effective during sporadic operation periods. A wide range of legitimate changes confound anomaly diagnosis and make baseline establishment for \"Normal\" operation difficult. The increasing frequency of these sporadic operations (e.g. due to continuous deployment) is exacerbating the problem.
