使用预留实例和承诺使用折扣减少支出
在项目中应用承诺使用折扣
承诺使用折扣不能应用于短时间的突发使用。如果购买了
50
个
vCPU
的承诺使用折扣，
那么你不能运行半个月的
100
个
vCPU
并获得全额折扣。再次回顾优惠券的类比，单个“优
惠券”不能同时应用于多个资源。
承诺使用折扣可以是通用的，也可以是内存优化的，一种类型的承诺使用折扣不能应用
于另一种资源使用类型。如果你买的是通用的承诺使用折扣，那么它们不会给内存优化
的实例打折，反之亦然。并不是所有的
GCP
实例类型都可以应用承诺使用折扣。
你以一到三年的期限购买承诺使用折扣，它们不会自动续订。当旧的承诺到期时，你可
以通过购买替代承诺来续保。其他折扣计划如持续使用折扣，不能适用于承诺使用折扣
支持的
vCPU
和内存。
承诺使用折扣表示
vCPU
和内存使用率之和。
4
个
vCPU
的承诺可以对更多
vCPU
实
例应用部分折扣。例如，一个运行
16
个
vCPU
的实例将以承诺使用的折扣接收
4
个
vCPU
，其余
12
个
vCPU
以正常价格接收。由于没有应用承诺使用折扣，所以剩余的
12
个
vCPU
可以应用持续使用折扣。
最后，值得注意的是，承诺使用折扣以特定的顺序分配给最昂贵的机器类型 ：
1.
定制机器类型
2. Sole-Tenant
节点组
3.
预定义的机器类型
这确保了你在申请资源时可以获得最好的折扣。

正如长久以来传言和广泛预期的那样，微软在

年底加入了预留实例的盛会，并在
