Adding a second private subnet - Amazon WorkSpaces Secure Browser

Adding a second private subnet

In the previous step, you created a VPC with one public subnet and one private subnet. Complete the following steps to add a second private subnet to your VPC. We recommend that you add a second private subnet in a different Availability Zone than your first private subnet.

To add a second private subnet

  1. In the navigation pane, choose Subnets.

  2. Select the first private subnet that you created in the previous step. On the Description tab, below the list of subnets, make a note of the Availability Zone for this subnet.

  3. On the upper left of the subnets pane, choose Create Subnet.

  4. For Name tag, enter a name for the private subnet. For example, WorkSpaces Secure Browser Private Subnet2.

  5. For VPC, select the VPC that you created in the previous step.

  6. For Availability Zone, select an Availability Zone other than the one you're using for your first private subnet. Selecting a different Availability Zone increases fault tolerance and helps prevent insufficient capacity errors.

  7. For IPv4 CIDR block, specify a unique CIDR block range for the new subnet. For example, if your first private subnet has an IPv4 CIDR block range of 10.0.1.0/24, you could specify a CIDR block range of 10.0.2.0/24 for the second private subnet.

  8. Choose Create.

  9. After your subnet is created, choose Close.
