Citrix ADC 13.0

Deploy a Citrix ADC VPX instance on Google Cloud Platform

You can deploy a Citrix ADC VPX instance on Google Cloud Platform (GCP). A VPX instance in GCP enables you to take advantage of GCP cloud computing capabilities and use Citrix load balancing and traffic management features for your business needs. You can deploy VPX instances in GCP as standalone instances. Both single NIC and multi NIC configurations are supported.

Supported features

A VPX instance running in GCP supports the following features:

  • Load Balancing
  • ICA Proxy
  • Content Switching
  • Citrix ADC AAA
  • Rewrite
  • Responder
  • RDP Proxy
  • nFactor
  • LDAP
  • VPN (CVPN/Full)
  • GSLB

Limitation

  • IPv6 is not supported

Hardware requirements

VPX instance in GCP must have minimum of 2 vCPUs and 4 GB RAM.

Prerequisites

  1. Install the “gcloud” utility on your device. You can find the utility at this link: https://cloud.google.com/sdk/install

  2. Download the NSVPX-GCP image from the Citrix download site.

  3. Upload the file(for example, NSVPX-GCP-12.1-50.9_nc_64.tar.gz) to a storage bucket on Google by following the steps given at https://cloud.google.com/storage/docs/uploading-objects.

  4. Run the following command on the gcloud utility to create an image.

gcloud compute images create <IMAGE_NAME> --source-uri=gs://<STORAGE_BUCKET_NAME>/<FILE_NAME>.tar.gz --guest-os-features=MULTI_IP_SUBNET

It might take a moment for the image to be created. After the image is created, it appears under Compute > Compute Engine in the GCP console.

Points to note

Consider the following GCP-specific points before you begin your deployment.

  • After creating the instance, you cannot add or remove any network interfaces.
  • For a multi-NIC deployment, create separate VPC networks for each NIC. One NIC can be associated with only one network.
  • For a single-NIC instance the GCP console creates a network by default.
  • Minimum 4 VPCUs are required for an instance with more than two network interfaces.
  • If IP forwarding is required, you must enable IP forwarding while creating the instance and configuring the NIC.

Scenario: deploy a multi-NIC, multi-IP standalone VPX instance

This scenario illustrates how to deploy a Citrix VPX standalone instance in GCP. In this scenario, you create a standalone VPX instance with multiple NICs. The instance communicates with back-end servers (the server farm).

Deploy vpx gcp scenario

Create three NICs to serve the following purposes.

NIC Purpose Associated with VPC network
NIC 0 Serves management traffic (Citrix ADC IP) Management network
NIC 1 Serves client-side traffic (VIP) Client network
NIC 2 Communicates with back-end servers (SNIP) Back-end server network

Also, set up the required communication routes between the instance and the back-end servers, and between the instance and the external hosts on the public internet.

Summary of deployment steps

  1. Create three VPC networks for three different NICs.
  2. Create firewall rules for ports 22, 80, and 443
  3. Create an instance with three NICs

Note: Create instance in the same region where you’ve created the VPC networks.

Create VPC Networks

Create three VPC networks that is associated with management NIC, client NIC, and server NIC. To create a VPC network, log on the Google console > Networking > VPC network > Create VPC Network. Complete the required fields, as shown in the screen capture, and click Create.

Similarly, create VPC networks for client and server-side NICs.

Note: All three VPC networks must be in the same region, which is asia-east1 in this scenario.

Create firewall rules for ports 22, 80, and 443

Create rules for SSH (port 22), HTTP (port 80), and HTTPS (port 443) for each VPC networks. For more information about firewall rules, see Firewall Rules Overview.

Create the VPX instance

  1. Log on to the GCP console.
  2. Under Compute, hover over Compute Engine, and select Images.
  3. Select the image, and click Create Instance.

    Create GCP instances

  4. Select an instance with 4 VPCUs, to support multiple NICs.
  5. Click the networking option from Management, security, disks, networking, sole tenancy to add the additional NICs.

    Note: Container image is not supported on VPX instances on GCP. Add GCP nics

  6. Under Networking interfaces, click the edit icon to edit the default NIC. This NIC is the management NIC.
  7. In the Network interfaces window, under Network, select the VPC network you created for management NIC.

  8. For the management NIC, create a static external IP address. Under the External IP list, click Create IP address.

  9. In the Reserve a new static IP address window, add a name and description and click Reserve.

  10. Click Add network interface to create NICs for a client and server-side traffic.

GCP additional nics

After you’ve created all the NICs, click Create to create the VPX instance.

Create vpx gcp instance

The instance appears under VM instances.

New VPX gcp instance

Use the GCP SSH or the serial console to configure and manage the VPX instance.

GCP ssh console

Points to note after you’ve deployed the VPX instance on GCP.

  • Log on to the VPX with user name nsroot and instance ID as password.

  • After the first logon, change the default password.

  • For collecting tech support bundle, run the command shell /netscaler/showtech_cloud.pl instead of the customary show techsupport.

Citrix ADC VPX licensing

A Citrix ADC VPX instance on GCP requires a license. The following licensing options are available for Citrix ADC VPX instances running on GCP.

  • Subscription-based licensing: Citrix ADC VPX appliances are available as paid instances on GCP marketplace. Subscription-based licensing is a pay-as-you-go option. Users are charged hourly. The following VPX models and license editions are available on GCP marketplace.

    VPX model License editions
    VPX10 Standard, Advanced, Premium
       
  • Bring your own license (BYOL): If you bring your own license (BYOL), see the VPX Licensing Guide at http://support.citrix.com/article/CTX122426. You have to:
    • Use the licensing portal within Citrix website to generate a valid license.
    • Upload the license to the instance.
  • Citrix ADC VPX Check-In/Check-Out licensing: For more information, see Citrix ADC VPX Check-In/Check-Out Licensing.

VPX Express for on-premises and cloud deployments does not require a license file. For more information on Citrix ADC VPX Express see the “Citrix ADC VPX Express license” section in Citrix ADC licensing overview.

GDM templates to deploy a Citrix ADC VPX instance

You can use a Citrix ADC VPX Google Deployment Manager (GDM) template to deploy a VPX instance on GCP. For details, see Citrix ADC GDM Templates.
