ABSTRACT
Human-induced faults play a large role in systems reliability. In cloud platforms, system administrators may inadvertently make catastrophic mistakes, like deleting a virtual disk with important data. Providing rollback for cloud operations can reduce the severity and impact of such mistakes by allowing to revert back to a known, good state. In this paper, we present a scalable approach to rollback operations that change state of a system on proprietary cloud platforms. In our previous work, we provided a system that augments cloud APIs and provides roll-back operation using an AI planner. However, the previous system eventually suffers from the exponential complexity inherent to AI planning tasks. In this paper, we divide and parallelize rollback plan generation, based on characteristics unique to the rollback scenario. Through experimental evaluation, we show that this approach scales better than the previous, naive approach, and effectively avoids the exponential behavior.
