dc.description.abstract Multi-tenancy is a key pillar of cloud services. It allows dif- ferent tenants to share computing resources transparently and, at the same time, guarantees substantial cost savings for the providers. However, from a user perspective, one of the major drawbacks of multi-tenancy is lack of con gura- bility. Depending on the isolation degree, the same service instance and even the same service con guration may be shared among multiple tenants (i.e. shared multi-tenant ser- vice). Moreover tenants usually have di erent - and in most of the cases - con icting con guration preferences. To over- come this limitation, this paper introduces a novel approach to support user-centric adaptation in shared multi-tenant services. The adaptation objective aims to maximise ten- ants' satisfaction, even when tenants and their preferences change during the service life-time. This paper describes how to engineer the activities of the MAPE loop to sup- port user-centric adaptation, and focuses on the analysis of tenants' preferences. In particular, we use a game theoretic analysis to identify a service con guration that maximises tenants' preferences satisfaction. We illustrate and motivate our approach by utilising a multi-tenant desktop scenario. Obtained experimental results demonstrate the feasibility of the proposed analysis. en_US
