This topic describes basic terms about Virtual Private Cloud (VPC).

Term Description
VPC A VPC is a private network deployed on Alibaba Cloud. VPCs are logically isolated from each other. You can create and manage cloud resources in your VPC, such as Elastic Compute Service (ECS), Server Load Balancer (SLB), and ApsaraDB RDS instances.
vSwitch A vSwitch is a basic network device that connects different cloud resources. When you create a cloud resource in a VPC, you must specify a vSwitch to which the cloud resource is connected.
vRouter A vRouter is a virtual router that connects all vSwitches in a VPC and serves as a gateway that connects the VPC to other networks. A vRouter also forwards network traffic based on the route entries in the route table.
Route table A route table consists of route entries in a vRouter.
Route entry Each item in a route table is a route entry. A route entry specifies the next hop address for the network traffic that is destined for a destination CIDR block. Route entries are classified into system route entries and custom route entries.
