云爆发(cloud bursting)是一个应用部署模式,其应用运行在私有云(private cloud)或数据中心(data center)中,当计算能力的需求达到顶峰时则动态地向云服务器请求一定量的计算(或存储)能力。这种混合云(hybrid cloud)部署的好处是,企业只有在请求了额外的云服务器能力的情况下才需要支付费用。
对于企业而言,IaaS的巨大价值通过云爆发(cloudbursting)概念实现—云爆发是指当需要的计算资源最多时将任务卸载到云环境的过程。
For businesses, the greatest value of IaaS is through a concept known as cloudbursting-the process of off-loading tasks to the cloud during times when the most compute resources are needed.
这些灰云是埃亚·菲亚·德拉冰川上的火山3月20号爆发所产生的,这是从1821年以来这座火山的第一次喷发。
The dust cloud is a result of a volcanic eruption at the Eyjafjallajoekull glacier which erupted on March 20, for the first time since 1821.
不过,如果我们借鉴一下历史的话,那么一旦云计算真正获得成功,争论必将再度爆发。
But if history is any guide the controversy is sure to flare up again once cloud computing really takes off.
