With the advent of the age of the Knowledge Economy, the desire for knowledge has been growing gradually. E-learning not only escapes from the limitations of time and space but allows researchers to develop related services via an open and powerful environment (i.e. cloud computing) through the development of information communication techniques and the popularity of portable devices. In this paper, we will introduce the two core mechanisms, asynchronous caching and adaptive delivery that integrate in the cloud environment. The first mechanism takes advantage of background scheduling to allow partial content processing and downloading in parallel. The second pays more attention to personalization service provision in accordance with situations such as location, time, and external information. The system optimizes the pervasive learning environment through the processing of the mechanisms mentioned above in the cloudbased environment.
