云中的冰山：云计算的其他风险
Icebergs in the Clouds: the Other Risks of Cloud Computing
摘要：
从管理和效率的角度来看，云计算很有吸引力，但也带来了已知和未知的风险。众所周知的和激烈争论的信息安全风险，由于软件漏洞，内部攻击和侧通道，例如，可能只是“冰山一角。随着多样化的、独立开发的云服务共享更加流畅和积极的多路复用硬件资源池，负载平衡和其他反应机制之间不可预测的交互可能导致动态不稳定或“崩溃”。“非透明的分层结构，其中替代云服务可能看起来独立，但共享深层隐藏的资源依赖关系，可能会产生意想不到的和潜在的灾难性故障相关性，让人想起金融业崩溃。最后，云计算加剧了本已困难的数字保存挑战，因为只有基于云的应用程序或服务的提供商才能存档云工件及其数据的“实时”功能副本，以进行长期的文化保存。本文探讨了这些在很大程度上未被认识到的风险，提出了我们应该在我们的社会经济结构不可避免地依赖于一个方便但可能不稳定的计算模型之前研究它们的理由。
英文摘要：
Cloud computing is appealing from management and efficiency perspectives, but brings risks both known and unknown. Well-known and hotly-debated information security risks, due to software vulnerabilities, insider attacks, and side-channels for example, may be only the "tip of the iceberg." As diverse, independently developed cloud services share ever more fluidly and aggressively multiplexed hardware resource pools, unpredictable interactions between load-balancing and other reactive mechanisms could lead to dynamic instabilities or "meltdowns." Non-transparent layering structures, where alternative cloud services may appear independent but share deep, hidden resource dependencies, may create unexpected and potentially catastrophic failure correlations, reminiscent of financial industry crashes. Finally, cloud computing exacerbates already-difficult digital preservation challenges, because only the provider of a cloud-based application or service can archive a "live," functional copy of a cloud artifact and its data for long-term cultural preservation. This paper explores these largely unrecognized risks, making the case that we should study them before our socioeconomic fabric becomes inextricably dependent on a convenient but potentially unstable computing model.
