Method for constructing UDDI (universal description, discovery and integration) extended model in cloud computing environment

Abstract

The invention discloses a method for constructing an UDDI (universal description, discovery and integration) extended model in a cloud computing environment. When a cloud service provider registers, basic information, quality information and resource information of service are registered into an extended UDDI model, and a register agent receives the information and processes the information; and when a cloud service user queries, querying is carried out in the extended UDDI model by virtue of the basic information, the quality information and the resource information of the service, and a query agent receives the information and processes the information. The method disclosed by the invention considers the characteristic of the cloud computing environment, the quality information and the resource information of the cloud service are extended into the existing UDDI model, and when the cloud service provider registers the service, the quality information and the resource information of the cloud service also can be registered; and the cloud service user also can screen the service by utilizing the quality information and the resource information of the service as constraint conditions by virtue of the extended UDDI model.

Description

technical field [0001] The invention relates to a construction method of a UDDI extension model in a cloud computing environment, and belongs to the technical field of Web service application in a cloud computing environment. Background technique [0002] With the continuous development of the Internet and Web Services in standards, implementation technologies (SOAP (Simple Object Access Protocol, Simple Object Access Protocol), UDDI (Universal Description Discovery and Integration, unified description, discovery and integration protocol) and WSDL (Web Services Description Language , Web service description language: an XML language used to describe Web services and explain how to communicate with Web services)) and other aspects continue to mature, so Web services have become one of the key technologies to realize cloud service. Under the SOA computing paradigm, UDDI (Universal Description, Discovery and Integration), as the unified registration center of Web Services, play...

Problems solved by technology

However, in the environment of cloud computing, UDDI cannot well satisfy the concept of "XaaS (X as a service, everything is a service)" in cloud computing. The main problems are: 1) The existing UDDI does not provide direct non- Functional description mechanism, service users cannot quickly select services that meet their quality requirements among services with the same function; 2) The existing UDDI model can only conveniently register and discover SOA (Service-Oriented Architecture, Service-Oriented Architecture ), there is no effective registration and discovery mechanism for generalized services in the cloud environment
