Cloud computing storage optimization based on stacked file system Guo Wan Zhangxiaofung The redundancy caused by a large number of virtual mirrors in the cloud environment will result in lower resource utilization and the use of deduplication to ease the need for storage space and network bandwidth, but there are also problems in handling performance degradation. In this paper, a cloud storage optimization scheme based on stacked file system is proposed. The scheme utilizes a scalable file system to store a small amount of modification information of a user to a virtual instance on a read-write disk, storing the virtual image in a reading disk, saving only a small amount of modification information for the virtual instance at a time, without saving ...

A low-cost cloud storage scheme based on hybrid strategy Li Songtao Jin Xin to ensure high availability of cloud storage system data, reduce data storage cost and bandwidth cost, and shorten access time of data objects, a new scheme called Cache size Adaptive Determination (carom) is proposed. Carom combines the traditional method based on caching strategy and error correcting code to improve the elasticity and efficiency of cloud file system. In addition, in order to achieve the balance between the cache size and its benefit, an adaptive method based on the general cost convex function is proposed to realize the adaptive selection of cache size. On the basis of real world documents ...

Cloud computing provides IT professionals with greater flexibility on how to deliver services. When there is a sudden change in the demand for a new project or workload, it can either hand over the work to a business provider or internally transfer resources until the peak period is passed. But this flexibility can also pose a cyber threat. For remote transfer applications, the company needs a good network connection between the data Center Web site and the public cloud provider, and the user will not feel degraded. There are two forms of good connections: the necessary bandwidth and the lower latency. Most organizations have an effective network connection to support e-mail, Web ...
