With the development of the cloud computing, increasing application and service based on cloud can be used by end-users. However, for these applications, the end-users can only use them passively. Without the programming experience, the end-users hardly involve their knowledge and awareness into the logic of applications. Cloud computing can provide large storage and computing resources for end-users on demand, and the Web of Things and sensor network can provide various kinds of information which is beyond the users’ own sense. In our opinion, the end-users in cloud computing environment have the ability to develop and design the function of applications by themselves through their knowledge and awareness. Therefore, we proposed the Cloud-Brain, a knowledge-based developing approach for end-user in cloud computing. In our approach, the presentation of fact and knowledge in cloud is considered. The rule engine and service-oriented architecture are involved in processing the knowledge in the cloud. End-users can upload their knowledge and awareness in the form of rule into cloud. At the same time, the system collects facts and data from Web of Things or sensor network. The actions in these rules, which have matching facts, call the web service or other function for users. A prototype was implemented to verify the feasibility of this method. Here, we also present a case study to demonstrate the functionality, performance, and potential of the approach.
