From the dawn of computing to the early 1980s, mainframes were the dominant server for all corporate workloads. Virtualization emerged in the 1960s with mainframes because of the need to have multiple systems running on the same machine. But, as smaller machines became more powerful and could handle more workloads, customers moved away from mainframes. This change resulted in reduced up-front costs for hardware, but it made IT operations more complex because different hardware, operating systems, storage, and networking were being juggled in a heterogeneous network environment. The issue of making all systems work harmoniously together became even worse as the number of servers proliferated through the 1990s. VMware saw this server proliferation and devised ways to package the operating systems, applications, and hardware inside virtual machines so that networking, storage, and computing power are all treated as resource pools that are collected and managed through a virtualization layer. * /data/Worlds-Tallest_Skyscrapers.htm 排名建築物國旗城市高度樓層年份 1台北101(Taipei 101) 台北 509米 101層 2004年 2 雙子星塔一座(Petronas Tower 1) 吉隆坡 452米 88層 1998年 3 雙子星塔二座(Petronas Tower 2)
