云计算安全之名词解释 – cloud bursting

Cloud Bursting是Amazon技术专家Jeff Barr创造的名词,讲的是如何使用云计算来解决在线零售网站季节性“突发”流量带来的“溢出”请求。也就是短时间的、时效性很强的那种突发流量,IT自己采购硬件扩容,ROI不是很合算,因为有效的使用时间很短。这时候就是云计算大显身手的商业时刻show time。因为云计算服务天生就是“租”的,随用随租的模式使得云服务更有效率地解决季节性、或事件性突发业务。

说直白一点,Cloud Bursting从技术角度上看,就是原来的流量负载分担技术,不同的就是使用云服务来作为辅助性数据中心。
