Software-as-a-Service Composition in Cloud Computing Using Genetic Algorithm

Cloud computing is a new IT paradigm. Over the last few years, there has been a trend of increasing adoption of a new software delivery model called Software-as-a-Service (SaaS) in the new IT paradigm. While the availability of SaaS in cloud computing has yet created a challenge for the service-oriented computing community, we believe it is only a matter of time that SaaS will grow exponentially to a stage where manual SaaS composition becomes impossible. In order to better prepare ourselves for this challenge, this paper proposes a multi-tenant enabled SaaS composition framework for cloud computing. While there have already been studies involved in tackling service composition in cloud computing, most of them ignore a key feature that is specific to cloud computing, that is multi-tenancy. This paper proposes a SaaS composition framework that can be used to automatically build SaaS in cloud computing.
