Advances in intelligent grid and cloud computing

Excerpt

Grid and Cloud Computing (GCC) frameworks have been one of the most popular research topics in recent years. These technologies are very important for supporting efficient user collaboration, since various resources for a project may be geographically distributed and heterogeneous (Foster and Kesselman 1999). Users can transparently access resources and services without worrying about how many services the platform has and where the services are located (Jung 2009). Especially, cloud computing can be seen as the next natural step towards the grid-utility model. However, advanced technologies and issues still need to be investigated, such as the appropriate platform, hybrid cloud architecture, service discovery and intelligent management, workflow (Jung 2011), QoS issues, green issues, cost-models, and so on, to provide transparent, secure, and efficient service access behind the cloud computing platform (Danylevych et al. 2010; Jung 2012b). In addition, a well-defined model and effective economics are useful for coordinating services and resources scattered throughout the world. A range of achievements and implementation experiences are required to drive sustained development and success in this area. …
