CSB: Cloud service bus based public SaaS platform for small and median enterprises

Cloud computing technology is put on more and more attentions for decreasing the IT budget of small and median enterprises. But the heterogeneous, distributed and dynamic properties of current SaaS software hamper the creations of one universal SaaS platform to securely integrate the often-used software for the enterprise. In this paper, we propose our public SaaS platform based on SOA architecture, which aims integrate the manufacture business software and with one universal entrance portal for small and median enterprises to online use software as OA, E-Mail, ERP, SCP and etc. The platform adopts cloud service bus to compatibly support the SOA based software and easily combine the primitive mechanisms of SaaS software as data access, user control, authority overlap and etc. The openness of SOA will permit more software can be integrated on the cloud computing platform without modification. The architecture is verified on our CN-online SaaS platform which is providing the commercial service for Chinese enterprises.
