Towards high level SaaS maturity model: Methods and case study
Yong Zhang, Shijun Liu, Xiangxu Meng · 2009
This paper introduces a software as a service (SaaS) application which is designed and delivered in high level maturity model. In order to realize the configurability, metadata is used to define all the variability points of the application. Meanwhile, JMX is used to manage the metadata so that changed metadata can be hot deployed immediately during runtime. Scalability is discussed both in application layer and data layer. Integration requirements and roadmap between SaaS application and on-premise applications are introduced. What's more, service surrogate extended from SCA and a message engine are used to meet the integration requirements in business processes.
