Cloud computing is a widely used technology with three basic service models such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). This paper focuses on the PaaS model. Open source PaaS model provides choice of cloud, developer framework and application service. In this paper detailed study of four open PaaS packages such as AppScale, Cloud Foundry, Cloudify, and OpenShift are explained with the considerable architectural component aspects. We also explained some other PaaS packages like Stratos, Stakato and mOSAIC briefly. In this paper we present the comparative study of major open PaaS packages.
