Advanced platforms that have a limited instance-level ability to provide metering and billing often opt to provide generalized billing models in which there is a flat fee to run application code.
在计费和计量方面存在实例层功能局限的高级平台，会选择提供通用计费模式，这种模式在运行应用程序代码时会产生固定费用。
If metering is based on transactions and leveraging the cloud computing cost allocation model, be sure to include cost-specific design patterns in your application code.
如果计量是基于事务，并且利用云计算成本分配模型，那么要确定将成本特定的设计模式包含在您的应用程序代码中。
[where] the service delivery components, such as billing, metering, and logging, are built by the application vendor and integrated into the application stack.
[其中]服务交付组件，如计费、计量和日志由应用厂商构建，并集成到应用组合中。
