Abstract:

The purpose of cloud computing is to provide the services of sharing resources to different users which is called cloud sharing. The paper explores the cloud computing definition of ICWS and its actors. After discussing three major actors of the cloud sharing, such as providers, developers and users, the paper not only abstracts two actors which are provider and user, but also analyzes their interactive relationship in the resource sharing. What is more, it puts forward three interactive patterns about cloud sharing which are P2C, C2C and P2P, and then analyzes how they share cloud resources among the interactive processes.

Key words: Cloud computing, Cloud sharing, Community cloud, Inter cloud
