Auto-scaling, a key property of cloud computing, allows application owners to acquire and release resourceson demand. However, the shared environment, along with theexponentially large configuration space of available parameters, makes configuration of auto-scaling policies a challenging task. Inparticular, it is difficult to quantify, a priori, the impact of a policyon Quality of Service (QoS) provision...
We present a fully automated technique for compositional verification of probabilistic systems. Our approach builds upon a recently proposed assume-guarantee framework for probabilistic automata, in which assumptions and guarantees are probabilistic safety properties, represented using finite automata. A limitation of this work is that the assumptions need to be created manually. To overcome this,...
