翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Elasticity (cloud computing) ： ウィキペディア英語版 Elasticity (cloud computing) In cloud computing, elasticity is defined as the degree to which a system (or a particular cloud layer) autonomously adapts its capacity to workload over time. In the cloud computing context, ″capacity″ refers to the maximum workload a system (or a particular cloud layer) can handle as bound by its service level objectives. Elasticity is a defining characteristic that differentiates cloud computing from previously proposed computing paradigms, such as grid computing. The dynamic adaptation of capacity, e.g., by altering the use of computing resources, to meet a varying workload is called "elastic computing". In general, an elastic cloud application or process has three elasticity dimensions, ''Cost'', ''Quality'', and ''Resources'', enabling it to increase and decrease its cost, quality, or available resources, as to accommodate specific requirements. ==Example== Let us illustrate elasticity through a simple example of a service provider who wants to run a website on an IaaS cloud. At moment $t\_0$, the website is unpopular and a single machine (most commonly a virtual machine) is sufficient to serve all web users. At moment $t\_1$, the website suddenly becomes popular, for example, as a result of a flash crowd, and a single machine is no longer sufficient to serve all users. Based on the amount of web users simultaneously accessing the website and the resource requirements of the web server, it might be that ten machines are needed. An elastic system should immediately detect this condition and provision nine additional machines from the cloud, so as to serve all web users responsively. At time $t\_2$, the website becomes unpopular again. The ten machines that are currently allocated to the website are mostly idle and a single machine would be sufficient to serve the few users who are accessing the website. An elastic system should immediately detect this condition and deprovision nine machines and release them to the cloud. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Elasticity (cloud computing)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
