    • enableDnsHostnames

      @Stability(Stable) public Vpc.Builder enableDnsHostnames(Boolean enableDnsHostnames)
      Indicates whether the instances launched in the VPC get public DNS hostnames.

    • maxAzs

      @Stability(Stable) public Vpc.Builder maxAzs(Number maxAzs)
      Define the maximum number of AZs to use in this region.

      If the region has more AZs than you want to use (for example, because of EIP limits), pick a lower number here. The AZs will be sorted and picked from the start of the list.

      If you pick a higher number than the number of AZs in the region, all AZs in the region will be selected. To use "all AZs" available to your account, use a high number (such as 99).

      Be aware that environment-agnostic stacks will be created with access to only 2 AZs, so to use more than 2 AZs, be sure to specify the account and region on your stack.

      Specify this option only if you do not specify availabilityZones.

      Default: 3

      Parameters:
      maxAzs - Define the maximum number of AZs to use in this region. This parameter is required.

      Default: - One NAT gateway/instance per Availability Zone

      Parameters:
      natGateways - The number of NAT Gateways/Instances to create. This parameter is required.
      Returns:
