Manage Private Network

  • VPC

VPC is your private network on the cloud. You can choose the IP address range, configure routing tables and gateways, etc. After creating a VPC, you can also add additional network segments to expand the network range.

  • Subnet

After creating a VPC, you can divide one or more subnets into the VPC. A network can be separated into subnets. Instances in different subnets of the same network can communicate securely.

Manage VPC

View VPCs

On the left menu bar, go to Private ->VPC, to view VPCs list.

Create a VPC

  1. On the left menu bar, go to Private Network-> VPC ,and click Create VPC.

  2. Choose a location. Select the location where you need your VPC. Since VPCs are region-specific, only instances within that location can join the VPC.

  3. Configure the VPC IP range. The range of IP addresses that can be used by instances assigned to this subnet.

  4. Label the VPC. Enter an alphanumeric string (containing only letters, numbers, and hyphens) to identify the VPC. A good label should provide some indication as to the purpose or intended use of the VPC.

  5. Add Subnet, and label the subnet, configure the subnet IP Address range. VPC subnet ranges must be in the RFC1918 IPv4 address space designated for private networks. That said, it cannot overlap with the 192.168.128.0/17 range set aside for Private IP addresses on Compute Instances.

  6. Click the Create VPC button to save your VPC. You can now see that VPC on the VPC page.

Delete a VPC

  1. On the left menu bar, go to Private Network-> VPC ,and click on the Delete button next to the corresponding VPC you would like to delete. You are prompted to confirm deletion of the VPC. Click Delete to proceed.

Only a VPC without any Instances assigned can be deleted.

Considerations

  • Up to 10 subnets can be created on a VPC.

  • A subnet is located within a single data center.

  • Each subnet can have at most one IPv4 CIDR block.

  • Each service assigned to a subnet must have a unique IPv4 address in the defined range.

Valid IPv4 Ranges for a Subnet

When defining an IPv4 range for a subnet, use a CIDR block within the RFC1918 specification that can accommodate the number of instances you anticipate being assigned to the subnet. Your subnet must be within the following blocks:

  • 10.0.0.0/8

  • 172.16.0/12

  • 192.168.0.0/16 (excluding 192.168.128.0/17 which is reserved for the private IP address feature)

View Subnets

On the left menu bar, go to Private ->Subnets, to view the Subnets list.

Creat a Subnet

Up to 10 subnets can be added to each VPC.

  1. On the left menu bar, go to Private Network-> Subnet, and click Create Subnet.

  2. Choose a VPC.

  3. Configure the Subnet IP range.

  4. Label the Subnet.

  5. Click the Create Subnet button to save your subnet. You can now see that Subnet on the Subnet page.

Once a subnet has been created, only its label can be edited. You cannot modify the CIDR block.

Delete a Subnet

  1. On the left menu bar, go to Private Network-> Subnet, and click on the Delete button next to the corresponding Subnet you would like to delete. You are prompted to confirm deletion of the Subnet. Click Delete to proceed.

Only a Subnet without any instances assigned can be deleted.
