DICE fault injection tool

Sheridan, Craig; Whigham, Darren; Artač, Matej (2016)
Projects: EC | DICE (644869)
In this paper, we describe the motivation, innovation, design, running example and future development of a Fault Inject Tool (FIT). This tool enables controlled causing of cloud platform issues such as resource stress and service or VM outages, the purpose being to observe the subsequent effect on deployed applications. It is being designed for use in a DevOps workflow for tighter correlation between application design and cloud operation, although not limited to this usage, and helps improve...

Compact Markov-modulated models for multiclass trace fitting

Casale, Giuliano; Sansottera, Andrea; Cremonesi, Paolo (2016)
Projects: EC | DICE (644869)
Markov-modulated Poisson processes (MMPPs) are stochastic models for fitting empirical traces for simulation, workload characterization and queueing analysis purposes. In this paper, we develop the first counting process fitting algorithm for the marked MMPP (M3PP), a generalization of the MMPP for modeling traces with events of multiple types. We initially explain how to fit two-state M3PPs to empirical traces of counts. We then propose a novel form of composition, called interposition, whic...
