Abstract

One of the key properties driving the popularity of cloud computing is the elasticity of multi-tenant business process. However, performing elasticity at the business process and the SaaS (Software as a Service) levels independently may only result in significant resources waste relating to the scalability, complex logic and long-running of the cloud applications. In this paper, we propose a holistic approach to dynamically manage elasticity mechanisms based on functional dependencies between the multi-tenant process and its involved services. This research is based on a service pattern for enabling multi-level elasticity control and analyzing the elasticity impact of invoked services on quality of the affected processes. Furthermore, we define an auto-scaling algorithm for enforcing multi-criteria dependencies for the elasticity control. Evaluation of our approach on a realistic situation shows its efficiency.
控制多租户业务流程的弹性依赖关系
推动云计算普及的关键属性之一是多租户业务流程的弹性。然而,在业务流程和SaaS(软件即服务)级别单独执行弹性可能只会导致与云应用程序的可伸缩性、复杂逻辑和长时间运行相关的大量资源浪费。在本文中,我们提出了一种基于多租户进程及其相关服务之间的功能依赖关系来动态管理弹性机制的整体方法。本研究基于一种服务模式,该模式支持多级弹性控制,并分析被调用服务对受影响流程质量的弹性影响。此外,我们定义了一种自动缩放算法,用于实施弹性控制的多标准依赖关系。对我们的做法在现实情况下的评价表明它是有效的。
