| Component | Description | Advantages |
|---|---|---|
| Virtual private cloud | Users can customize the network address space, and addresses between multiple VPCs can overlap with each other | Traditional data centers do not allow overlapping address spaces, making it impossible to create multiple identical network environments (e.g., disaster recovery networks or test environments identical to production environments) |
| Subnet | Users can flexibly customize network IP ranges | Similar services are grouped into the same subnet for unified server management. It supports integration of Baidu Cloud Compute (BCC), dedicated cloud compute (DCC) sub-instances, and bare metal compute (BBC) into virtual private cloud |
| Route table | Flexibly schedule, manage, and control traffic within the VPC | Achieve simple and effortless management and scheduling of subnet-level traffic through the global route table |
| Security group | Configure IP + port-level access control for BCC instances, DCC dedicated instances, load balancer instances, and cloud database instances within the VPC | Configure bidirectional traffic access control for hosts within the VPC significantly enhances service security |
| ACL | Achieves subnet-level deployment firewall function | Flexible and simple configuration, supporting allow/deny policies to achieve subnet-level security access control |
| Elastic network interface | A flexible network interface card mountable across multiple cloud hosts for seamless migration | Deploy a high-availability cluster via elastic network interfaces to achieve rapid failover and refined network management |
| Service network interface card | A convenient, secure, and private channel can be provided within the VPC to connect with external services such as BOS | No EIP is required, and it supports private network access and hybrid cloud scenarios with flexible usage |
| IPv6 gateway | VPC's total egress for accessing the public Internet via IPv6 | Flexibly configure egress and ingress bandwidth for IPv6 Internet access |
| NAT gateway | Multiple Baidu Cloud Compute instances within a VPC share the same set of public IPs for egress access and can also provide Internet services | It supports bandwidth up to 5G, and realizes high reliability through HA-based automatic failover and recovery |
| VPN gateway | Via VPN, VPC establishes VPN tunnels with multiple IDC environments of customers to achieve hybrid cloud | HA-based automatic failover and recovery ensure high reliability |
| Peering connections | Secure connections of multiple VPCs via intranet | Flexibly achieve high-speed network connectivity for multiple users' services within the same region or across regions |
| Dedicated gateway | API for VPC connection to physical dedicated line | Support bandwidth up to 100G, enabling stable, high-speed, secure, and flexible connectivity between VPC and user IDC |
| Flow logs | Used to record network flow information sent and received by Baidu Cloud Compute Instances in the VPC | Facilitate traffic analysis, visualization, fault diagnosis, and network architecture optimization |
