Exploring System Resiliency and Supporting Design Methods
arXiv - CS - Software Engineering Pub Date : 2020-09-13 , DOI: arxiv-2009.05903
James J. Cusick

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.

探索系统弹性和支持设计方法

本文对系统弹性和弹性设计方法的行业观点进行了调查,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,该文档涵盖了操作响应时间表、故障源和分类。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回顾来讨论弹性设计。然后包括十多种弹性设计模式,供读者考虑自己的解决方案。还涵盖了支持非功能性设计主题,包括可用性、性能、安全性、可靠性以及使用可靠性框图的可靠性分配。此外,回顾了故障模式和影响分析,并讨论了弹性成熟度模型。最后,介绍了几个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组建议。
