从管理和效率的角度来看，云计算具有吸引力，但带来已知和未知的风险。由于软件漏洞，内部攻击和侧渠道，众所周知和备受瞩目的信息安全风险可能只是“冰山一角”。随着多样化的独立开发的云服务的共享，越来越流畅，多重的硬件资源库，负载平衡和其他反应性机制之间的不可预测的交互可能会导致动态不稳定性或“崩溃”。非透明的分层结构，替代云服务可能会独立但具有深厚的隐藏资源依赖性，可能会产生意想不到的灾难性故障相关性，让人联想到金融业崩溃。最后，云计算加剧已经存在的数字保护挑战，因为只有基于云的应用程序或服务的提供商才能将云伪像的功能副本及其用于长期文化保护的数据存档。本文探讨了这些在很大程度上无法识别的风险，这使得我们应该在社会经济结构变得密不可分地取决于方便但潜在不稳定的计算模型之前对其进行研究。
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.
