“滴答”一秒钟过去了。你知道在这一秒钟里面,互联网上发生了什么变化吗?大数据犹如一块大蛋糕,激发起人们投身未来的激情的同时,也给人们当头一棒:现有的架构体系并不足以支撑大数据时代。而在目前来看,发展成熟的虚拟化和当下红的发紫的,似乎成了大数据价值实现的左膀右臂……

虚拟化和云计算:大数据价值的左膀右臂
云数据中心

  一、云计算帮助大数据平台降低复杂性,简化运维,提升资源活性和利用效率

  云计算通过基于网络的服务交付,将硬件等基础架构融合为无形的IT资源,并借助、分布式计算、并行计算、虚拟化、网络存储和统一管理等技术手段,实现IT服务的无缝化、定制化和伸缩性交付。

二、云计算帮助云数据中心降低成本,有利于将更多资金投入到增值业务中

三、云计算可支撑基于大数据的灵活高效IT服务,满足多种个性化需求

  很多企业IT应用虚拟化程度仅有20%-30%。但随着的逐步成熟与落地,云数据中心也越来越被企业接受。当然,这种虚拟化在云数据中心中的应用也就更加广泛了。

  了解大数据的读者都知道,Hadoop是所有大数据解决方案中最具成长性的平台,它通过集群搭建起的高性能计算和存储平台,利用分布式架构对海量数据(包括结构和非结构数据)进行分析和处理。在这种情况下,也许很多人会误以为虚拟化运行在SAN上,而Hadoop却在本地上运行,从而主观认为虚拟化不适合大数据平台。甚至有人会认为,虚拟化会给IT系统带来更多资源开销,降低Hadoop性能。

  其实,大数据平台下的Hadoop,更多的是基于集群版(包括开源和英特尔发行版),而不是单机版。通过虚拟存储架构下的共享存储(SAN或者NAS),可实现更简便高效的部署,并且实现集群的自动。

  在这种情况下,引入虚拟化解决方案就成为了破解这些难题的“救命稻草”了。虚拟化、甚至基于计算、网络、存储各个模块的全面虚拟化,有助于降低成本和提升集群系统的可用性和可靠性,避免Hadoop集群带来的昂贵成本负担,使得广大中型企业也可以实现大数据的分析和应用,而且也可以帮助提升大数据的服务价值。

  另外一种情况是,基础设施的全面虚拟化,还可以顺应大数据几何级数增长的发展态势,从而从一开始就紧随业务/大数据价值挖掘的需求不断推进,提升大数据价值内涵。
