云计算已经成为一种流行的计算环境，它为小型到大型企业提供了一系列交付解决方案，具有灵活的模型，允许在最低成本内为大量数据提供计算能力和存储空间。这些天来，计算范式正在转向基于效用的按需付费模型和许多讨论，但仍然没有云计算的规范定义。在本文中，我们提出了一个面向服务的云计算分类谱，它更侧重于云的服务工程视角。我们支持云工程的论点是一种分层的结构化方法“即服务”，例如安全即服务、容错即服务、架构即服务。本文的主要贡献是确定了一个广泛的分类法，旨在更好地理解功能以及架构组件，可以受益于云化。我们描述了每个子分类（架构、核心服务、安全性、容错性、管理服务等）。详细地说此外，我们提出了一个比较研究的几个云系统的基础上分类。此外，它还确定了企业云环境中存在的许多挑战和机遇。版权所有© 2011约翰威利父子有限公司.
Cloud computing has emerged as a popular computing milieu that provides a range of delivering solutions for small to large enterprises with a flexible model that allows a computing power and storing space for the large volumetric data within minimum cost. These days, computational paradigm is shifting towards utility‐based pay‐as‐you‐go model and many discussion aside, but there remains no canonical definition of cloud computing yet. In this paper we have proposed a service‐oriented taxonomical spectrum of cloud computing, which is more focused on the service engineering perspective of cloud. Our argument behind cloud engineering is a layered structural approach ‘as a Service’ such as security as a service, fault tolerance as a service, architecture as a service. The main contribution of this paper is to identify a wide spectrum of taxonomy, aiming at a better understanding of functional as well as architectural components that could benefit from cloudification. We describe each sub‐taxonomy (architecture, core services, security, fault tolerance, management services etc.) in details. In addition, we present a comparative study of several cloud systems based on taxonomy. Moreover, it also identifies many challenges and opportunities that exist on the landscape of enterprise cloud.
