In the Cloud computing infrastructure, the sharable e-Learning platform can be proposed to provide a good learning environment for learners. Three layer architecture of the e-Learning platform is provided to facilitate the sharing, reusing learning objects and interoperability among various learning content efficiently. The middleware layer imports an indexing module and a metadata transformation module to complete metadata exchange among acknowledged e-Learning standards. Therefore, learners can make use of available learning objects without having to be affiliated with other LMS. The proposed e-Learning platform based on Cloud computing infrastructure would allow the independent LMS embedded in different e-Learning standards to share the learning objects. In short, you can say cloud computing will help huge amount of learning objects to be accessed reliably and flexibly over the Internet.
