论文摘要
本文介绍了对系统弹性和弹性设计方法的行业观点的调查，并简要介绍了组织弹性主题。从弹性，系统能力，逆境和弹性生命周期的复合定义开始，该文档随后涵盖了操作响应时间表，故障来源和分类。接下来，通过对系统理论的介绍以及对权衡分析和弹性依赖性的综述，讨论了弹性的设计。然后包括多种弹性设计模式，供读者考虑自己的解决方案。还涵盖了支持非功能设计主题，包括可用性，安全性，可靠性以及使用可靠性框图的可靠性分配。此外，审查了故障模式和效应分析，并讨论了弹性成熟度模型。最后，提供了一些弹性设计示例，以及有关如何在IT环境中应用系统弹性概念和方法的一系列建议。
This paper provides a survey of the industry perspective on System Resiliency and Resiliency design approaches and briefly touches on Organizational Resiliency topics. Beginning with a composite definition of Resiliency, System Capabilities, Adversities, and the Resiliency Life-cycle the document then covers Operational Response Timelines, Failure Sources and Classifications. Next, Design for Resiliency is discussed with an introduction to Systems Theory and a review of Trade-off Analysis and Resiliency Dependencies. Then more than a dozen Resiliency Design Patterns are included for the reader to consider for their own solutioning. Supporting non-functional design topics including Availability, Performance, Security, Reliability as well as Reliability Allocation using Reliability Block Diagrams are also covered. Additionally, Failure Mode and Effect Analysis is reviewed, and a Resiliency Maturity Model is discussed. Finally, several Resiliency Design Examples are presented along with a set of recommendations on how to apply System Resiliency concepts and methods in an IT environment.
