DATA CENTER MULTI-VIRTUAL NETWORK JOINT MAPPING METHOD BASED ON COMPLEMENTARY FEATURES OF SERVICE STATISTICS

The present invention relates to a method and apparatus for performing service deployment in a data center. The method comprises: receiving a plurality of service requests; estimating a mean value and a variance of service requirements of a plurality of services; determining, on the basis of the mean value and the variance of the service requirements, whether the services are services to be reconstructed; and deploying, in the same schedulable server, services to be reconstructed which have the same or similar variances, in order to allocate resources on the same schedulable server, so as to meet the service requirements of the services to be reconstructed which have the same or similar variances. The embodiments of the present invention can significantly improve the utilization rate of server resources of a data center, and improve the quality of service. La présente invention concerne un procédé et un appareil pour effectuer un déploiement de service dans un centre de données. Le procédé consiste à : recevo
