In this paper we describe the architecture of a real time environment for numerous remote experiments. The environment is created with web standards as HTML5 such that no plug-in needs to be installed by the user. Users are able to use the remote lab simultaneously and in collaboration. This collaboration between users is made feasible by adopting a message broker. Finally, by using Google Coder, developers can easily change or create the user interface of their remote experiments and share experiments in the cloud.
