Formal Modeling and Verification of Cloud Elasticity with Maude and LTL

International audienceElasticity allows Cloud systems to adapt to the demand by (de)provisioning resources as the input workload rises and drops. Given the numerous overlapping factors that impact their elastic behavior, the specification and verification of Cloud elasticity is a particularly challenging task. In this paper, we propose a Maude-based approach to formalize Cloud systems’ elastic behaviors, as a first step towards the verification of their correctness through a LTL (Linear Temporal Logic) state-based model-checking technique
