Sponsored by the Technical Committee on Services Computing (IEEE Computer Society), the Fourth IEEE 2011 International Conference on Cloud Computing (CLOUD 2011) will be co-located with the 7th IEEE 2011 World Congress on Services (SERVICES 2011), the 9th IEEE 2011 International Conference on Web Services (ICWS 2011), and the 8th IEEE 2011 International Conference on Services Computing (SCC 2011) to grow itself to continue to be the most prestigious professional conference dedicated to cloud computing.

“Change we are leading” is the theme of CLOUD 2011. Cloud Computing has become a scalable services consumption and delivery platform in the field of Services Computing. The technical foundations of Cloud Computing include Service-Oriented Architecture (SOA) and Virtualizations of hardware and software. The goal of Cloud Computing is to share resources among the cloud service consumers, cloud partners, and cloud vendors in the cloud value chain. The resource sharing at various levels results in various cloud offerings such as infrastructure cloud (e.g. hardware, IT infrastructure management), software cloud (e.g. SaaS focusing on middleware as a service, or traditional CRM as a service), application cloud (e.g. Application as a Service, UML modeling tools as a service, social network as a service), and business cloud (e.g. business process as a service).

In the fast growing Services Computing community, we have launched a series of events to promote and grow Cloud Computing in the past years. In 2002, we promoted Business Grid to share business processes and applications. In early 2008, The IEEE Transactions on Services Computing (TSC) has adopted Cloud Computing to be included in the taxonomy as a body of knowledge area of Services Computing. In July 2008, the IEEE International Conference on Services Computing (SCC 2008) has delivered a keynote panel “Business Cloud: Bridging The Power of SOA and Cloud Computing” and a keynote “Cloud Computing”. In September 2008, the 2008 IEEE International Conference on Web Services (ICWS 2008) has delivered a keynote “Web Services: Software-as-a-Service (SaaS), Communication, and Beyond” and a panel "Cloud Computing and IT as a Service: Opportunities and Challenges" to further motivate the community members to define Cloud Computing in various areas.

Based on the technology foundations and industry driving forces, the 2009 International Conference on Cloud Computing (CLOUD 2009) is created to provide a prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of Cloud Computing, identify emerging research topics, and define the future of Cloud Computing. CLOUD 2009 is the hot-topic conference co-located with the 2009 World Congress on Services (SERVICES 2009). The two well-established theme conferences, the 2009 IEEE International Conference on Web Services (ICWS 2009) held in July 2009 in USA and the 2009 IEEE International Conference on Services Computing (SCC 2009) held in September 2009 in India, also enjoyed the success of launching CLOUD-I 2009 and CLOUD-II 2009. CLOUD 2009 was jointly sponsored by IEEE Computer Society Technical Committee on Services Computing (TC-SVC) and Services Society. As a community, we have accomplished very well around CLOUD 2009's theme "Change We Can Lead" in 2009.

In July 2010, CLOUD 2010 was co-located with IEEE International Conference on Web Services (ICWS 2010), IEEE International Conference on Services Computing (SCC 2010), and IEEE World Congress on Services (SERVICES 2010) in Miami, Florida, USA. Three cloud-centric keynotes were delivered: "Cloud Computing in an Outcome Centric World," "Securing Data in the Cloud-Challenges and Research Directions," and "Thinking outside the Box: How Cloud, Grid, and Services can Make Us Smarter."

To discuss this emerging enabling technology of the modern services industry, CLOUD 2011 invites you to join the largest academic conference to explore modern services and software sciences in the field of Services Computing, which was formally promoted by IEEE Computer Society since 2003. From technology foundation perspective, Services Computing has become the default discipline in the modern services industry.

It is required that all submissions MUST cite related work published in the proceedings of ICWS, SCC, CLOUD, SERVICES, APSCC, ECOWS, and related journals including TSC, JWSR, and IJBPIM.

CLOUD 2011 tries to attract researchers, practitioners, and industry business leaders in all the following areas to help define and shape cloud computing, and its related modernization strategy and directions of the services industry. You are invited to submit research, engineering, and business innovation papers to the following areas:

Infrastructure Cloud
Software Cloud
Application Cloud
Business Cloud
Service-Oriented Architecture in Cloud Computing
Virturalization of Hardware Resources
Virtualization of Software Resources
Cloud Computing Consulting Methods
Design Tool for Cloud Computing
Maintenance and Management of Cloud Computing
Cloud Computing Architecture
Cloud Applications in Vertical Industries
