Ç C LOUD is a novel computing paradigm that builds on the foundations of distributed computing, grid computing, networking, virtualization, service orientation, and marketoriented computing. Cloud provides flexible resource allocation on demand with the promise of realizing elastic, Internet-accessible computing on a pay-as-you-go basis. Cloud services include infrastructure such as computing and storage servers, platforms such as operating systems, and application software; these are often

Cloud offers or, rather, promises numerous benefits from both the technology perspective such as increased availability, flexibility, and functionality, and the business perspective such as reduced capital and operational expenditure and shorter turnaround times for new services and applications. But, before this paradigm can be widely accepted, many issues have yet to be resolved, including flexible architectural solutions, efficient resource virtualization techniques (CPU, storage, and link virtualization), performance modeling and optimization, modeling and development techniques for Cloud-based systems and applications, reliability modeling, techniques and policies for ensuring security and privacy, and many others. Additional areas that need attention due to recent developments in the area of smart devices (phones, tablets, and the like) include mobile and roaming access, mobile and dynamic applications, incorporation of modern wireless and cellular technologies into the Cloud paradigm, and the development of new virtualization, scheduling, and transport schemes to achieve energy saving and enable green computing to become an intrinsic part of the Cloud. To help gain additional and much needed insights into those issues, the IEEE Transactions on Parallel and Distributed Systems (TPDS) has created a special issues devoted to recent advances in Cloud computing from the parallel and distributed systems perspective.
