Cloud systems are increasingly being managed by operation programs termed operators,
which automate tedious, human-based operations. Operators of modern management …

Virtual devices based on device emulation have been widely used in lab research of mobile
app testing for their efficiency and low cost. However, it remains controversial to use virtual …

Mobile emulation, which creates full-fledged software mobile devices on a physical
PC/server, is pivotal to the mobile ecosystem. Unfortunately, existing mobile emulators …

In this paper, we i) analyze and classify real-world failures of Kubernetes (the most popular
container orchestration system), ii) develop a framework to perform a fault/error injection …

Metastable failure is a recent abstraction of a pattern of failures that occurs frequently in real-
world distributed storage systems. In this paper, we propose a formal analysis and modeling …

Large distributed systems are often built by assembling off-the-shelf (OTS) components, eg,
components, services, processes, etc., developed independently. The current approach is to …

Incident reports describe what happened when a system's performance was degraded, or
when it stopped working entirely. They document the measurements made, the changes …
