1. A management method in a hybrid cloud environment comprising a first data center and a second data center, the first data center being configured to provide a non-public cloud service, the second data center being configured to provide a public cloud service, 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, and the method comprises:
creating, by a management apparatus, a gateway, wherein the gateway is located in the second data center, 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;
