虚拟化
曾经有一段时间，计算机被视为由大型金融、教育或研究机构管理的设备。因为
计算机是非常昂贵的，
IBM
等厂商建立大规模的小型机和大型机处理多用户同时
处理，利用许多今天仍在使用的虚拟化的概念。用户将从大型机中获得计算时间，
从瘦终端或哑终端访问它们。用户提交计算资源争用的作业。集中式系统通过队列、
虚拟操作系统和管理资源分配的系统计费进行管理。所有繁重的计算都由主机和
操作人员处理，最终用户基本上看不到。这些系统的设计在很大程度上是由安全
性和可靠性驱动的，因此大量的努力被应用于包含用户环境和数据冗余。虚拟化
在数据中心空间获得了牵引力，并成为云计算领域创新的基石：

今天，虚拟化不仅限于计算，它也被应用到网络、存储和
I/O
中，以减轻虚拟化对
性能的影响，越来越多的硬件支持虚拟化。最后但并非最不重要的一点是，虚拟
化环境中的安全也是一个活跃的研究领域。要了解更多关于虚拟化的各个方面，
