CLOUD SYSTEM BASED ON PUBLIC CLOUD SERVICE, PACKET PROCESSING METHOD, AND RELATED APPARATUS

Abstract

A cloud system based on a public cloud service including a virtual private cloud (VPC) and a load balancer. The VPC includes a first subnet, a second subnet, and a third subnet. The load balancer includes a first elastic network interface ENI and a second ENI. In the cloud system provided in this solution, when sending a request packet to a second instance in the second subnet, a first instance in the first subnet forwards the packet to a packet processing service node in the third subnet via the first ENI and the second ENI. In this way, the packet is forwarded by the packet processing service node in the third subnet without additional packet header encapsulation, thereby simplifying a packet processing operation, and improving performance of the cloud system.
