The cloud computing is the fastest growing concept in IT industry. The IT companies have realized that the cloud computing is going to be the hottest topic in the field of IT. Cloud Computing reduces cost by sharing computing and storage resources, merged with an on demand provisioning mechanism relying on a pay-per use business model. Due to varied degree of security features and management sc...

Introduction: Cloud Computing Technology (CCT) can exist in many forms and is fundamentally a complex system-of-systems. In PART II of this report, we proved theoretically through a fault tree analysis that users of cloud computing systems are more at risk than users of non-cloud computing systems, given similar system configurations. In PART III, we demonstrate the above conclusion with a phys...

Received Apr 10, 2017 Revised Aug 24, 2017 Accepted Aug 31, 2017 The issue on how to effectively deliver video streaming contents over cloud computing infrastructures is tackled in this study. Basically, quality of service of video streaming is strongly influenced by bandwidth, jitter and data loss problems. A number of intelligent video streaming algorithms are proposed by using different tech...

Virtual cloud network services let users have their own private networks in the public cloud. IPsec gateways are growing in importance accordingly as they provide VPN connections for customers to remotely access these private networks. Major cloud providers offer IPsec gateway functions to tenants using virtual machines (VMs) running a software IPsec gateway inside. However, dedicating individu...

The advent of smartphones in recent years has changed the wireless landscape. Smartphones have become a platform for online user interface to cloud databases. Cloud databases may provide a large set of userprivate and sensitive data (i.e., objects), while smartphone users (i.e., subjects) provide location-sensitive information. Secure and private services in wireless accessing to cloud database...

While demands on video traffic over mobile networks have been souring, the wireless link capacity cannot keep up with the traffic demand. The gap between the traffic demand and the link capacity, along with time-varying link conditions, results in poor service quality of video streaming over mobile networks such as long buffering time and intermittent disruptions. Leveraging the cloud computing...
