亚马逊的系统大部分时间都在闲置,但它还是不得不把系统建得足够大,以免在流量激增时崩溃。创始人贝索斯说:“有时只利用不到10%。”把这些闲置的系统能力出租,就为客户及自己压缩了电脑应用成本。也许这一商业模式的出现非常偶然,但将彻底改变 IT 行业。未来人们获得电脑运算能力,就像从电厂买电一样平常;等于说,人们不必再拥有强大的电脑,就像不必拥有发电机一样。 Amazon’s system is mostly idle for a long time, but it still has to build the system large enough to avoid a crash when the traffic surge. Founder Bezos said: “Sometimes, less than 10% is used.” Leasing these idle system capabilities has compressed the cost of computing for our customers and ourselves. Perhaps this business model is very accidental, but it will completely change the IT industry. In the future, people have computer computing power that is just as common as buying power from a power plant; tantamount to saying that people no longer have to have powerful computers, just as they do not have to own a generator.
