语言与云语言
商品销售成本与资本在云计算中如何结合
我们最近发现一家英国零售商正在开发一个新的购物平台，并以一种有趣的方式遵
循上述原则。
该公司将产品生产过程中使用的
EC2
时长作为资本化资产进行核算，该资产在此期
间没有支出。它之所以可以做到这一点，是因为开发中的产品没有产生任何收入。
这个零售商利用
EC2
时长创造了一项会在未来产生收入的资产，就如电力公司用煤
炭制造钻石，而非用来发电。
一旦该购物平台上线，资本化的
EC2
成本就被分摊至该平台产生收入的时期。注意，
购物平台非实物资产，因此它能够被分期付款，而非折旧。
在云计算中，预留实例通常会在
1~3
年内被分期付款至其使用期间。
抽象化以助理解
人脑往往无法计算过大或过小的数字。例如，如果产品每分钟消耗
1
美元，那么计算
10
美元的使用时间就相对简单。然而，如果某资源的成本为每小时
0.0034
美元，那么我们
需要一个计算器来计算
10
美元换取的使用时间。同时，数字的格式很重要，如果没有
固定格式，“
100000000
”这样的数字就无法阅读。大多数人通过数零的个数，并添加逗
号来确定数目大小。
人类另一个与数字有关的问题是，我们往往无法建立“规模思维”，这对于团队计算以千、
百万、千万为单位的金额来说是一个头疼的问题。
在
FinOps
基金会议中，有一个伙伴分享了如何运用抽象思维辅助
FinOps
。他强调说，
十亿与二十亿的差距乍一听不大，但实际上变化巨大。
我们发现，云计算支出庞大的公司很难为工程师提供有意义的支出指标。大家可以想象，
一个公司如果每年的云计算支出为 ...
