This work tackles this challenge by proposing a novel approach that is referred to as Mixed-Tenancy. It allows customers to express their deployment constraints about if or even with whom they want to share the application. To be more precise, the approach enables the customer to make that choice not just for the entire application but specifically for individual application components and their underlying infrastructure stack. Based on these constraints a deployment is computed that uses infrastructure as efficiently as possible by being in compliance with all constraints. Such a deployment is referred to as valid and optimal. Thus, Mixed-Tenancy is an approach that allows operators to exploit economies of scale by still keeping customers' hesitations concerning the privacy threats of Multi-Tenancy in mind.
This work contributes to the creation of Mixed-Tenancy systems by introducing a generic model that allows capturing customers’ deployment constraints. Thereby, the model allows customers to express complex constraints (e.g. “sharing shall only be permitted with companies from Europe but not with competitors”) while still allowing the operator to keep its customer base secret. In addition the problem of computing a valid and optimal deployment is formally defined and analyzed. Furthermore, it is proven to be NP-hard and two intuitive heuristics are introduced and compared.
Finally, this work evaluates the applicability of Mixed-tenancy by investigating a case study in the area of cloud computing. This is done by introducing Mixed-Tenancy to an existing cloud application, called OpenERP, currently used in industry. It thereby demonstrates that the Mixed-Tenancy approach may indeed be successfully applied to real-world systems.

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
