云迁移：企业级IT系统向IaaS迁移的案例研究
Cloud Migration: A Case Study of Migrating an Enterprise IT System to IaaS
摘要：
本案例研究从整个企业的各种利益相关者的角度说明了将石油和天然气行业的IT系统从内部数据中心迁移到Amazon EC2的潜在好处和风险，从而超越了提供商提供的典型但狭隘的财务和技术分析。我们的研究结果表明，案例研究中的系统基础设施在EC2上的5年成本将减少37%，并且使用云计算可能会消除21%的支持要求。这些发现似乎足够重要，需要将系统迁移到云端，但我们的利益相关者影响分析显示，这存在重大风险。虽然使用云的好处是有吸引力的，我们认为，重要的是，企业决策者考虑的整体组织的影响所带来的变化与云计算，以避免实施本地优化的成本组织范围内的性能。
英文摘要：
This case study illustrates the potential benefits and risks associated with the migration of an IT system in the oil & gas industry from an in-house data center to Amazon EC2 from a broad variety of stakeholder perspectives across the enterprise, thus transcending the typical, yet narrow, financial and technical analysis offered by providers. Our results show that the system infrastructure in the case study would have cost 37% less over 5 years on EC2, and using cloud computing could have potentially eliminated 21% of the support calls for this system. These findings seem significant enough to call for a migration of the system to the cloud but our stakeholder impact analysis revealed that there are significant risks associated with this. Whilst the benefits of using the cloud are attractive, we argue that it is important that enterprise decision-makers consider the overall organizational implications of the changes brought about with cloud computing to avoid implementing local optimizations at the cost of organization-wide performance.
