Advisor ： Cho-Chin Lin Student ： Yu-Chi Huang

Outline

Introduction & Review Preliminaries:cloud computing/ service computing/pervasive computing Comparisons Conclusion

Cloud computing

Infrastructure as a Service （ IaaS ） -----Amazon 的 AWS(Amazon Web Services )

Platform as a Service （ PaaS ） -----Google’s Apps Engine 、 Force.com

SaaS -----Supply System Intergration （ SI ）

Preliminaries

Service computing(service-oriented computing)

Pervasive computing(Ubiquitous computing)

Comparison

cloud, service, and pervasive computing

The classical model of computer architecture

The I/O feature:cloud computing resembles that of service computing.

The storage feature :Cloud computing is closer to pervasive computing than service computing.

Virtualization 、 Aggregation 、Service Management

Conclusion

Based on the comparison

Research issues :

Pluggable computing entities to cloud applications

Data access transparency

Adaptive behavior of cloud applications

Automatic discovery of application quality
