大数据技术是指从各种各样类型的数据中，快速获得有价值信息的能力。适用于大数据的技术，包括大规模并行处理（MPP）数据库，数据挖掘电网，分布式文件系统，分布式数据库，云计算平台，互联网，和可扩展的存储系统。
大数据的应用：大数据是信息产业持续高速增长的新引擎。面向大数据市场的新技术、新产品、新服务、新业态会不断涌现。在硬件与集成设备领域，大数据将对芯片、存储产业产生重要影响，还将催生一体化数据存储处理服务器、内存计算等市场。在软件与服务领域，大数据将引发数据快速处理分析、数据挖掘技术和软件产品的发展。
云计算是基于互联网的相关服务的增加、使用和交付模式，通常涉及通过互联网来提供动态易扩展且经常是虚拟化的资源。云是网络、互联网的一种比喻说法。过去在图中往往用云来表示电信网，后来也用来表示互联网和底层基础设施的抽象。
云计算的主要应用：
云物联——“物联网就是物物相连的互联网”。这有两层意思：第一，物联网的核心和基础仍然是互联网，是在互联网基础上的延伸和扩展的网络；第二，其用户端延伸和扩展到了任何物品与物品之间，进行信息交换和通信。
云安全——一个从“云计算”演变而来的新名词。云安全的策略构想是：使用者越多，每个使用者就越安全，因为如此庞大的用户群，足以覆盖互联网的每个角落，只要某个网站被挂马或某个新木马病毒出现，就会立刻被截获。
云存储——在云计算概念上延伸和发展出来的一个新的概念，是指通过集群应用、网格技术或分布式文件系统等功能，将网络中大量各种不同类型的存储设备通过应用软件集合起来协同工作，共同对外提供数据存储和业务访问功能的一个系统。
