You can deploy a NetScaler VPX instance on the 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

All Premium, Advanced, and Standard features are supported on the GCP based on the license/version type used.

Limitation

  • IPv6 isn’t supported.

Hardware requirements

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

Points to note

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

  • After creating the instance, you can’t 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 vCPUs 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 NetScaler VPX standalone instance in GCP. In this scenario, you create a standalone VPX instance with many NICs. The instance communicates with back-end servers (the server farm).

GCP deployment scenario

Create three NICs to serve the following purposes.

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

Set up the required communication routes between the following:

  • VPX instance and the back-end servers.
  • VPX 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 an instance in the same region where you’ve created the VPC networks.

Step 1. 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 to Google console > Networking > VPC network > Create VPC Network. Complete the required fields, as shown in the screen capture, and click Create.

VPC networks for scenario

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.

Step 2. 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.

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

Scenario: Deploy a single-NIC, standalone VPX instance

This scenario illustrates how to deploy a NetScaler VPX standalone instance with a single NIC in GCP. The alias IP addresses are used to achieve this deployment.

GCP standalone deployment with single NIC

Create a single NIC (NIC0) to serve the following purposes:

  • Handle management traffic (NetScaler IP) in the management network.
  • Handle client-side traffic (VIP) in the client network.
  • Communicate with back-end servers (SNIP) in the back-end server network.

Set up the required communication routes between the following:

  • Instance and the back-end servers.
  • Instance and the external hosts on the public internet.

Summary of deployment steps

  1. Create a VPC network for NIC0.
  2. Create firewall rules for ports 22, 80, and 443.
  3. Create an instance with a single NIC.
  4. Add Alias IP addresses to VPX.
  5. Add VIP and SNIP on VPX.
  6. Add a load balancing virtual server.
  7. Add a service or service group on the instance.
  8. Bind the service or service group to the load balancing virtual server on the instance.

Note:

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

Step 1. Create one VPC network.

Create one VPC network to associate with NIC0.

To create a VPC network, do these steps:

  1. Log on to GCP console > Networking > VPC network > Create VPC Network
  2. Complete the required fields, and click Create.

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. At the prompt, change the password and save the configuration.

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

  • After deleting a NetScaler VM from GCP console, delete the associated NetScaler internal target instance also. To do so, go to gcloud CLI and type the following command:

     gcloud compute -q  target-instances delete <instance-name>-adcinternal --zone <zone>
 <!--NeedCopy-->

    Note:

    <instance-name>-adcinternal is the name of the target instance that must be deleted.
