Motivation of iVCE Project j
The internet-based Virtual Computing Environment (iVCE) i (i C ) : “friendly” “f ” Computing C Environment on the Internet
From Computer view to Networking view From Hardware Infrastructure to Service Infrastructure
10
Support large-scale resource sharing and coordination on Internet Provide trustworthy, trustworthy and transparent computing services/environment on-demand for users and applications
The purpose of the project: design mata models, mechanisms, and software platform to build such a computing environment
