A Loosely-coupled Semantic Model for Efficient Cloud Service Search and Retrieval. (2015)
Presentation / Conference Contribution
Fang, D., Liu, X., & Romdhani, I. (2015). A Loosely-coupled Semantic Model for Efficient Cloud Service Search and Retrieval. In W. Zimmerman, Y. W. Lee, & C. Reich (Eds.), Cloud Computing 2014: the Fifth International Conference on Cloud Computing, Grids

As cloud services propagate along with the rapid development of cloud computing, issues raised in service selection and retrieval processes become increasingly critical. While many approaches are proposed on the specification and discovery of cloud s... Read More about A Loosely-coupled Semantic Model for Efficient Cloud Service Search and Retrieval..

Critical Evaluation on jClouds and Cloudify Abstract APIs against EC2, Azure and HP-Cloud. (2014)
Presentation / Conference Contribution
Graham, S. T., & Liu, X. (2014). Critical Evaluation on jClouds and Cloudify Abstract APIs against EC2, Azure and HP-Cloud. In 2014 IEEE 38th International Computer Software and Applications Conference Workshops (COMPSACW), (510-515)

With Cloud Computing there comes new possibilities like programmability of Infrastructure via provider exposed APIs. These APIs can aid the concept of elasticity that is associated with the Cloud however, there is a trend that these APIs are provider...

Benefits Management provides an established approach for decision making and value extraction for IT/IS investments and, can be used to examine cloud computing investments. The motivation for developing an upper ontology for Benefits Management is th... Read More about An Upper Ontology for Benefits Management of Cloud Computing.

Cloud Migration Patterns: A Multi-Cloud Service Architecture Perspective. (2014)
Presentation / Conference Contribution
Jamshidi, P., Pahl, C., Chinenyeze, S., & Liu, X. (2014). Cloud Migration Patterns: A Multi-Cloud Service Architecture Perspective.

Many organizations migrate their on-premise software systems to the cloud. However, current coarse-grained cloud migration solutions have made a transparent migration of on-premise applications to the cloud a difficult, sometimes trial-and-error base...
