Distributed Computing in the 21st Century: Some Aspects of Cloud Computing
The Cloud Computing paradigm has gained considerable attention owing to the notable commercial success of many Cloud service providers. Typically, a Cloud Computing service provides its customers with resources as a utility, using a pay-as-you-go model. Thus, Cloud Computing customers can reduce costs related to the acquisition and management of complex IT infrastructures and Cloud service providers can make efficient use of large resource pools by consolidating multiple variable workloads. From the providers point of view a Cloud is a very large distributed system which poses many challenges, including monitoring, management, efficient resource sharing, fault-tolerance and so on.
