Query: Data Placement for Multi-Tenant Data Federation on the Cloud   Due to privacy concerns of users and law enforcement in data security and
privacy, it becomes more and more difficult to share data among organizations.
Data federation brings new opportunities to the data-related cooperation among
organizations by providing abstract data interfaces. With the development of
cloud computing, organizations store data on the cloud to achieve elasticity
and scalability for data processing. The existing data placement approaches
generally only consider one aspect, which is either execution time or monetary
cost, and do not consider data partitioning for hard constraints. In this
paper, we propose an approach to enable data processing on the cloud with the
data from different organizations. The approach consists of a data federation
platform named FedCube and a Lyapunov-based data placement algorithm. FedCube
enables data processing on the cloud. We use the data placement algorithm to
create a plan in order to partition and store data on the cloud so as to
achieve multiple objectives while satisfying the constraints based on a
multi-objective cost model. The cost model is composed of two objectives, i.e.,
reducing monetary cost and execution time. We present an experimental
evaluation to show our proposed algorithm significantly reduces the total cost
(up to 69.8\%) compared with existing approaches.
