云采用工具包：支持企业中的云采用决策
The Cloud Adoption Toolkit: Supporting Cloud Adoption Decisions in the Enterprise
摘要：
云计算承诺在企业内提供计算资源方面发生根本性的转变。本文介绍了决策者在评估其组织采用云计算的可行性时所面临的挑战，并介绍了我们的云采用工具包，该工具包是为支持这一过程而开发的。该工具包提供了一个框架，以支持决策者确定他们的关切，并将这些关切与可用于解决这些关切的适当工具/技术相匹配。成本建模是工具包中最成熟的工具，本文通过演示从业人员如何使用它来检查在云上部署IT系统的成本来展示其有效性。成本建模工具是使用一个组织的案例研究进行评估的，该组织正在考虑将其部分IT系统迁移到云。该案例研究表明，使用传统的“永远在线”方法在云上运行系统可能会降低成本效益，并且必须利用云的弹性来降低成本。因此，决策者必须能够对资源使用的变化及其系统部署选项进行建模，以获得准确的成本估计。
英文摘要：
Cloud computing promises a radical shift in the provisioning of computing resource within the enterprise. This paper describes the challenges that decision makers face when assessing the feasibility of the adoption of cloud computing in their organisations, and describes our Cloud Adoption Toolkit, which has been developed to support this process. The toolkit provides a framework to support decision makers in identifying their concerns, and matching these concerns to appropriate tools/techniques that can be used to address them. Cost Modeling is the most mature tool in the toolkit, and this paper shows its effectiveness by demonstrating how practitioners can use it to examine the costs of deploying their IT systems on the cloud. The Cost Modeling tool is evaluated using a case study of an organization that is considering the migration of some of its IT systems to the cloud. The case study shows that running systems on the cloud using a traditional "always on" approach can be less cost effective, and the elastic nature of the cloud has to be used to reduce costs. Therefore, decision makers have to be able to model the variations in resource usage and their systems deployment options to obtain accurate cost estimates.
