Cloud computing is a new paradigm of IT. It can provide all resources such as Software (SaaS), Platform (PaaS) and Infrastructure (IaaS) as a service over the internet. It also offers the opportunity to store a huge amount of data relatively cheaply. In cloud computing, user can access the services regardless of their location or computing device/platform they use. In these advantages, many researchers of e-learning area attempt to apply their process to cloud computing. In this paper, the authors propose service based e-learning system in cloud computing. In order to provide personalized learning process considering user's characteristics, they use the user profile data.
