  abstract = {The processes for deploying systems in cloud environments can
  be the basis for studying strategies for detecting and correcting errors
  committed during complex process execution. These cloud-based processes
  encompass diverse activities, and entail complex interactions between cloud
  infrastructure, application software, tools, and humans. Many of these
  processes, such as those for making release decisions during continuous
  deployment and troubleshooting in system upgrades, are highly error-prone.
  Unlike the typically well-tested deployed software systems, these
  deployment processes are usually neither well understood nor well tested.
  Errors that occur during such processes may require time-consuming
  troubleshooting, undoing and redoing steps, and problem fixing.
  Consequently, these processes should ideally be guided by strategies for
  detecting errors that consider trade-offs between efficiency and
  reliability. This paper presents a framework for systematically exploring
  such trade-offs. To evaluate the framework and illustrate our approach, we
  use two representative cloud deployment processes: a continuous deployment
  process and a rolling upgrade process. We augment an existing process
  modeling language to represent these processes and model errors that may
  occur during process execution. We use a process-aware discrete-event
  simulator to evaluate strategies and empirically validate simulation
  results by comparing them to experiences in a production environment. Our
  evaluation demonstrates that our approach supports the study of how
  error-handling strategies affect how much time is taken for task-completion
  and error-fixing.},
