With Java runtime-based application has been widely used in our enterprise application and mobile computing.We must maintain many machines in different types, like web server cluster,distributed database,virtual machines,hosting machines and so on.Cloud computing technology has been designed to manage those resources in efficiently way. Client agent can be installed in those host machines or virtual environment to monitor machine status.But with the size expand of the cloud domain,those client agents should be updated or reinstalled. OSGi is an industry standard for a lean Java-based component system with focusing on service-oriented architecture.In this issue,we present OSGi for the cloud computing environment allowing seamless deployment and update function in dynamic way.After use OSGi as the architecture foundation of client agent we use an underlying peer-to-peer infrastructure to provide,share and load OSGi bundles at runtime.Cloud computing bundles on-line warehouse has been established to support bundle download and on-line update.OSGi based on client agent can communication with cloud computing management system to monitor and manage cloud resource in real time.
