Abstract: Aspects of provisioning computing units based on improved failure resiliency are described. In one embodiment, an infrastructure component shared between a pair of computing units is identified. A failure rate for the infrastructure component is obtained, and a failure probability for a class of assigned computing units is computed based in part on the failure rate. A spread request related to the class of assigned computing units is also received. In response to the spread request, an altered composition of computing units is determined, and a difference between a failure probability for the altered composition of computing units and the failure probability for the class of assigned computing units is computed. In one embodiment, when a spread score improvement value associated with the difference meets a spread criteria of the spread request, the altered composition of computing units may be provisioned for use.

Abstract translation: 描述了基于改进的故障恢复性的供应计算单元的方面。 在一个实施例中，识别在一对计算单元之间共享的基础设施组件。 获得基础设施组件的故障率，并且部分地基于故障率计算一类分配的计算单元的故障概率。 还接收与分配的计算单元的类相关的扩展请求。 响应于扩展请求，确定计算单元的改变的组合，并且计算计算单元的改变的组合的故障概率与所分配的计算单元的类别的故障概率之间的差异。 在一个实施例中，当与差异相关联的扩展分数改善值满足扩展请求的扩展标准时，可以提供计算单元的改变的组合以供使用。
