云计算采用过程中的经验知识再利用（CS SE）---刘持诚

将遗产软件系统转移到云平台是一个越来越受欢迎的选择。但是，这样的努力可能存在风险，我们需要在采取任何行动之前对所涉及的要求和风险有一个正确的理解。在现在这个已经成熟的时机下，我们应该对系统迁移到云平台上可能提供的情况进行现实的评估，去了解导致无法满足系统品质目标的特殊情况，并认识学习应对措施。云迁移的知识体系虽然很有用，但在目前的文献中却比较分散。对于忙碌的从业者来说，在将遗产系统与云服务集成的情况下，他们很难消化以及综合利用这些知识体系并将其运用到实践中。我们在基于证据的软件工程和目标导向的建模方法之间，通过建立一个创新的协同作用来解决这个问题。我们开发了一个与系统云化相关的常见障碍和不稳定平台解决策略的证据库。在给定的云迁移场景的“系统化目标-障碍阐述”过程中，我们进一步利用了这个资源库。还展示了拟议框架的适用性。

原文题目：Reusing empirical knowledge during cloud computing adoption

原文：Moving legacy software systems to cloud platforms is an ever popular option. But, such an endeavour may not be hazard-free and demands a proper understanding of requirements and risks involved prior to taking any actions. The time is indeed ripe to undertake a realistic view of what migrating systems to the cloud may offer, an understanding of exceptional situations causing system quality goal failure, and insights on countermeasures. The cloud migration body of knowledge, although is useful, is dispersed over the current literature. It is hard for busy practitioners to digest, synthesize, and harness this body of knowledge into practice in a scenario of integrating legacy systems with cloud services. We address this issue by creating an innovative synergy between the approaches evidence-based software engineering and goal-oriented modelling. We develop an evidential repository of commonly occurred obstacles and platform agnostic resolution tactics related to making systems cloud-enabled. The repository is further utilized during the systematic goal-obstacle elaboration of given cloud migration scenarios. The applicability of the proposed framework is also demonstrated.
