VPC | It is a custom network address space, and the addresses between multiple VPCs can be overlapped with each other. | The address space overlap is not allowed in the traditional data center, and multiple identical network environments (disaster recovery network and test environment consistent with production environment) cannot be created. |
Subnet | Users can flexibly customize the IP address range. | It classifies the similar services into the same subnet to facilitate the unified management of user servers, and supports to bring the sub instance of BCC, DCC and BBC into the VPC. |
Security Group | It sets the IP + port level access control for BCC in VPC. | It sets the bidirectional traffic access control for CVM server in VPC, greatly improving the business security. |
ACL | It is the firewall component in VPC to implement the subnet-level security access control. | It flexibly sets the traffic of one or more subnets to meet the user's security requirements for different network deployments. |
Routing Table | It flexibly schedules, manages and controls the traffic in the VPC. | It simply and easily manages and schedules the subnet level traffic through the global routing table. |
Elastic Network Interface Card | It provides the CVM sever the network forwarding ability of multiple ENIs and IPs. | It helps users to route different types of traffic on the CVM server to different ENIs for the separate management, and realizes the fine management of network traffic. |
Service Network Interface Card | It realizes the convenient and safe access to the public services in VPC. | It needs not provide the elastic IP, but supports the private network access and is flexible for use. |
NAT Gateway | Multiple BCCs in the VPC share the same group of public network IPs for the external access, and SNAT and DNAT are supported. | It supports up to 5G bandwidth. It implements the automatic failover and recovery based on HA, achieving the high reliability. |
VPN Gateway | It builds the VPN tunnel with multiple IDC environments of customers to implement the hybrid cloud through VPN. | It supports up to 1G bandwidth. Based on HA, it implements the automatic failover and recovery to achieve the high reliability. |
Peering connection | It securely connects the private networks between multiple VPCs. | It flexibly realizes the high-speed network connection of multiple users business in the same region/different regions. |
ET Gateway | It is the interface for the VPC to the physical ET. | It supports up to 10 G bandwidth, and realizes the stable, high-speed, safe and flexible interconnection from the VPC to the user IDC. |
