1. A management method in a hybrid cloud environment comprising a first data center and a second data center, a same private network segment being configured for a first subnet of the first data center and a second subnet of the second data center, the method comprising:
creating, by a management apparatus, a gateway located in the second data center, wherein the gateway is remotely connected to the first subnet of the first data center through a communication tunnel, and the gateway is connected to the second subnet of the second data center;
configuring, by the management apparatus, the gateway to intercept a first address resolution protocol ARP request packet from a first device of the first subnet for a second device in the second subnet, and to return a first ARP reply packet to the first device, wherein the first ARP reply packet carries a first MAC address of the gateway; and
configuring, by the management apparatus, the gateway to store a correspondence, carried in the first ARP request packet, between an IP address of the first device and a MAC address of the first device.
