# PERF02-BP02 了解可用的计算配置和功能
<a name="perf_compute_hardware_understand_compute_configuration_features"></a>

 了解计算服务的可用配置选项和功能，帮助预置适量的资源并提高性能效率。

 **常见反模式：**
+  没有依据工作负载特征评估计算方案或可用的实例系列。
+  过度预置计算资源来满足高峰需求。

**建立此最佳实践的好处：**熟悉 AWS 计算功能和配置，以便使用经过优化的计算解决方案，满足工作负载特征和需求。

 **在未建立这种最佳实践的情况下暴露的风险等级：**中 

## 实施指导
<a name="implementation-guidance"></a>

 每种计算解决方案都有独特的配置和功能，可支持不同的工作负载特征和需求。了解这些方案如何完善工作负载，并确定哪些配置选项最适合您的应用程序。这些选项的示例包括实例系列、规模、功能（GPU、I/O）、突增、超时、函数大小、容器实例和并发。如果工作负载已经使用同一计算方案超过四周，并且预计这些特征在未来将保持不变，则可以使用 [AWS Compute Optimizer](https://aws.amazon.com/compute-optimizer/) 从 CPU 和内存角度查明当前计算方案是否适合工作负载。

## 实施步骤
<a name="implementation-steps"></a>
+  了解工作负载要求（如 CPU 需求、内存和延迟）。
+  查看 AWS 文档和最佳实践，了解有助于提高计算性能的推荐配置选项。以下是一些需要考虑的关键配置选项：
