Cloud computing is the latest technology that involves distributed computation over the Internet. It meets the needs of users through sharing resources and using virtual technology. The workflow user applications refer to a set of tasks to be processed within the cloud environment. Scheduling algorithms have a lot to do with the efficiency of cloud computing environments through selection of su...

Throughout the history of computing, there have been several paradigm shifts from main-frames to mini computing to microprocessing to networked computers. On track to be the next major paradigm shift is that of cloud computing. While the definitions are still being debated (see: http://videos. techielife.com/what-is-cloud-computing/video-online/ 2008/11/13), fundamentally, cloud computing can b...

This paper uses transaction cost theory to study cloud computing adoption. A model is developed and tested with data from an Australian survey. According to the results, perceived vendor opportunism and perceived legislative uncertainty around cloud computing were significantly associated with perceived cloud computing security risk. There was also a significant negative relationship between pe...

While most research regarding adoption of cloud computing by companies covers countries with highly developed IT infrastructure, cloud computing is actually used also in less IT-mature countries. Still, companies address cloud computing differently in countries with different levels of IT-maturity. This research explores cloud computing adoption factors in less IT-mature countries having Turkey...

The purpose of this paper is to present the design for providing security and higher authentication scheme for executing secure data transaction in an Organization field over Internet. There has been incessant change in technology day by day, so security mechanisms like authentication schemes are also required to be updated. Authentication schemes that involve more than single level for authent...

Blockchain technology is a distributed ledger with records of data containing all details the transactions carried out and among nodes present in network. All system are confirmed by consensus mechanisms, once stored cannot be altered. necessary behind Bitcoin, which popular digital Cryptocurrency. ''Cloud computing practice using network remote servers hosted on internet to store, manage, proc...

To support online index and range queries, the Distributed B-tree is adopted to index the mass and rapidly increasing data in cloud computing. But current Distributed B-tree has three defects: low degree of concurrency, frequent node splitting and high cost of updates in clients. For above mentioned defects, this paper presents efficient distribute Btree index in cloud computing environment, wh...
