The growing trend towards grid computing and cloud computing provides enormous potential for allowing dynamic, distributed and data demanding applications such as sharing and processing of large-scale scientific data. Cloud computing is the use of computing of sources (hardware and software) that are delivered as a service over a network. A main characteristic of the cloud services is that users' data are usually processed remotely in unknown machines that users do not operate. It can be converted into a significant roadblock to the wide adoption of cloud services.
