Abstract
Cloud system is an emerging paradigm and a large pool of computing resources
that makes use of existing technologies such as virtualization, service-orientation and grid
computing. In cloud computing, on demand services are delivered to users depending on the
service level agreements (SLA) between the service provider and the user. In order to
provide scalable business services and cost allocation flexibility for customers so that they
can choose their preferred services according to their budget, defining a cost-effective query
execution strategy within cloud environment is utmost important. Towards this effort, a cost
model for query execution at cloud computing based on both shared-disk and sharednothing
architecture is introduced in this paper. The complexity of the cost model has been
analyzed considering different cost factors that are demanding for cloud computing. Finally,
the cost model is illustrated with the help of an example.
