Design of SaaS OverCloud for 3-tier SaaS Compatibility over Cloud-based Multiple Boxes
Jungsu Han, JongWon Kim · 2017
With a growth in the popularity of ICT and Cloud technologies, the adoption of SaaS (Software as a Service) model is rapidly increasing. However, SaaS developers are still struggling with heterogeneities and inter-dependencies of their development and operation environments. In order to mitigate selected SaaS compatibility issues for heterogeneous underlying cloud infrastructures, we present a new approach, denoted as SaaS OverCloud, by enabling a specially-arranged razor-thin overlay layer and leveraging container-based on micro-services architecture. We then verify the conceptual feasibility of SaaS OverCloud model by enabling simplified 3-tier SaaS services over small-size cloud-based boxes.
