Caching Strategy

Cost-optimized cloud storage caching Strategy Tang Bing Zhang to improve the access rate of cloud storage and reduce the cost, a cost-optimized cloud storage caching strategy is proposed. Build a distributed File system locally and use it as a cache of remote cloud storage, using more than one desktop computer in a nearly free LAN environment. When a file is read, it first finds whether it is in the cache, if it exists, reads it directly from the cache, or if it does not, from the remote cloud store. The least Recently Used (LRU) algorithm was used for cache substitution to replace the unpopular data from the cache. To Amazon Simple ...

Nifty has been operating the site for a long time, and after the launch of the WYSIWYG web platform based on HTML5, users have built more than 54 million sites in the company, and most of them have less than 100 solar PV. Since the PV of each page is low, the traditional caching strategy does not apply. Even so, however, the company has done so with only 4 Web servers. Recently, Wix chief back-end engineer Aviran Mordo in "Wix architecture ...

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 ...
