CloudUDDI: An extended UDDI model for cloud services

With the rapid development of cloud computing, cloud service is becoming one of the research hotspots. As the current UDDI standard and implementation cannot describe the quality and low-level resources information of cloud service well, it is difficult to meet the new requirement of optimal cloud services query, selection and access. Therefore, the paper proposes an extended UDDI model-CloudUDDI, which is suitable for the cloud computing environment. It supports the presentation and storage of the quality and low-level resource information of cloud services for facilitating cloud service's registry and selection. The experimental results show that it improves the precision ratio of cloud services selection and effectively access the optimal services that meet both quality and low-level resource requirements.
