“…Literature [16][17][18] ensured the security of cloud mode from the perspective of network topology, secure data format and data transmission congestion control. As the increasingly widespread of cloud computing services, data visibility is different for different users and service providers, it needs flexible access control mechanisms [19][20][21], traditional access control methods can no longer fully adapt to the new environment. In cloud computing environment [22], semantic access control policy language is used to describe access policy design access control oriented ontology system based on this language as to enhance interoperability while ensuring data security, which is a kind of application combined cloud computing and semantic web technology.…”

Cloud computing aims to integrate more than one relatively low-cost computing entities into a perfect system of powerful computing capabilities, and distribute this powerful computing capabilities to end-users by the advanced business model. Traditional network marketing has played an important role in the e-commerce industry, bringing invaluable wealth for online transactions, but with the continuous improvement of people's living standard, traditional marketing methods can no longer meet the market requirements. This paper compares the difference between traditional network marketing and cloud marketing based on cloud computing, and creates a new cloud marketing model C-Marketing. Then the advantages of C-Marketing as a new hot spot in marketing are discussed. Finally some suggestions for improvement are proposed based on this.

“…Using network attached storage (NAS), downtime can be brought down to the order of milliseconds (Mian et al, 2011) but for a local persistent storage the downtime will be significantly higher. Migrating CPU state, migrating memory content (Ibrahim et al, 2011), migrating storage content (Hirofuchi et al, 2009a(Hirofuchi et al, , 2009b, and migrating network connections are the important steps to be followed in migrating a VM from source host do destination host. Clark et al (2011) proposed pre-copy migration technique.…”

Abstract:Processing large volumes of data to drive their core business has been the primary objective of many firms and scientific applications in these days. Cloud computing being a large-scale distributed computing paradigm can be used to cater for the needs of data intensive applications. There are various approaches for managing the workload on a data intensive cloud. Live migration of a virtual machine is the most prominent paradigm. Existing approaches to live migration use network attached storage where just the run time state needs to be transferred. Live migration of virtual machines with local persistent storage has been shown to have performance advantages like security, availability and privacy. This paper presents an optimised approach for migration of a virtual machine along with its local storage by considering the locality of storage access. Count map combined with a restricted block transfer mechanism is used to minimise the downtime and overhead. The solution proposed is tested by various parameters like bandwidth, write access patterns and threshold. Results show the improvement in downtime and reduction in overhead.

“…Storage can be migrated with algorithms similar to memory migration [3,16,10,32]. Network connections can be kept uninterrupted after migration using tunneling [29,3], VPN reconfiguration [32] or Mobile IPv6 [7].…”

“…Fortunately, state of the art systems allow to use live migration over WANs by migrating storage [3,16,10,32] and network connections [3,7,32]. However, the large amounts of data to migrate make live migration over WANs expensive to use, especially when considering migrations of virtual clusters rather than single VM instances.…”

Abstract. Live virtual machine migration is a powerful feature of virtualization technologies. It enables efficient load balancing, reduces energy consumption through dynamic consolidation, and makes infrastructure maintenance transparent to users. While live migration is available across wide area networks with state of the art systems, it remains expensive to use because of the large amounts of data to transfer, especially when migrating virtual clusters rather than single virtual machine instances. As evidenced by previous research, virtual machines running identical or similar operating systems have significant portions of their memory and storage containing identical data. We propose Shrinker, a live virtual machine migration system leveraging this common data to improve live virtual cluster migration between data centers interconnected by wide area networks. Shrinker detects memory pages and disk blocks duplicated in a virtual cluster to avoid sending multiple times the same content over WAN links. Virtual machine data is retrieved in the destination site with distributed content-based addressing. We implemented a prototype of Shrinker in the KVM hypervisor and present a performance evaluation in a distributed environment. Experiments show that it reduces both total data transferred and total migration time.
