Zusammenfassung:	A method, apparatus and system for domain name resolution in a data center system. The system comprises at least one physical server, a DNS server, and a distributed routing device. At least one virtual machine runs on each physical server. The virtual machines in a data center system are respectively located in at least two virtual private clouds (VPCs). A same domain name is managed in the at least two VPCs. The same domain name specifies different services in the at least two VPCs. The DNS server establishes correspondences between the NAT addresses of the virtual machines of users and VPC identifiers. The VPCs where different users are located are distinguished by means of the VPC identifiers, so as to determine the IP addresses corresponding to the domain name managed in the VPCs. L'invention concerne un procédé, un appareil et un système de résolution de nom de domaine dans un système de centre de données. Le système comprend au moins un serveur physique, un serveur DNS et un dispositif de routage distr
