Provision of U-city web services using cloud computing

U-city is a future city with high-tech and provides citizens many kinds of U-city services. Because necessary computing resources for U-city services are different, cloud computing that assigns and manages such resources dynamically must be supported in the U-city. As well, U-city portal must support one stop services for the execution of automatic operation to enable users to use U-city services on the web easily. To meet these requirements, we made a U-city portal that integrated various kinds of web services for cloud computing in the U-city altogether. We developed the Virtual Machine Job Manager(VMJM) of the U-city portal for one stop services on the cloud platform, which uses the OpenNebula virtual infrastructure and the Haizea as virtual machine resource management scheduler. It enables general users to execute and monitor U-city services on the virtual machines automatically without experts' knowledge. That is, in this paper, we present web services for cloud computing in the U-city.
