一种基于OpenStack的云应用开发框架

A Development Framework for Cloud Applications Based on OpenStack

云计算的迅速发展对云应用与云服务的开发提出了更高要求。然而,依靠提供商提供的云平台基本功能组件不能直接满足需求,对云平台进行二次开发会增加开发周期,降低开发速率。OpenStack是一个开源的云管理平台,为客户提供云基础架构服务,包括计算服务、存储服务和网络服务。以OpenStack为基础,针对虚拟机管理应用、存储应用和定制应用,设计并实现了一种云应用开发框架,融合了服务组合和元数据的设计思想。基于该框架实现了一个虚拟机定制系统,并验证了该设计框架的可用性和有效性。

Cloud computing market is developing rapidly, promoting the requirement of developing cloud applications and cloud service. However, the cloud platform provided by the platform vendor cannot be able to meet the requirements completely, and developers need secondary development, which increases development cycle and reduces the efficiency. OpenStack is an open source cloud computing platform, providing service of computing, storage and networking. Integrating ideas of service-oriented architecture and metadata, a development framework of cloud platform based on OpenStack is proposed for development of virtual machine management applications, storage application and custom application. Based on the framework, a virtual machine customization system is developed, which verifies the usability and efficiency of the development framework.
