Citrix Gateway Service for StoreFront
Important information:
- Citrix Gateway Service for StoreFront is now generally available in the Citrix DaaS environments.
- This document describes the steps that you can perform to deploy Citrix Gateway Service for StoreFront in a scenario where you prefer to use the on-premises NetScaler Gateway for authentication and on-premises StoreFront for enumeration.
- Citrix Gateway Service for StoreFront is not supported in Citrix Cloud Japan and Citrix Cloud Government environments.
Overview
Citrix Gateway Service for StoreFront is a cloud-based HDX solution that provides secure remote access to resources accessed from on-premises StoreFront. You can leverage the scalability and reliability of Citrix Cloud (for HDX proxy) without changing your on-premises StoreFront and on-premises NetScaler Gateway environments.
Consider that you are a Citrix DaaS customer using on-premises StoreFront as your enterprise application store and on-premises NetScaler Gateway for remote access. If you are looking for an option to leverage a cloud-hosted remote access solution (HDX proxy) while maintaining on-premises StoreFront as your user portal and on-premises NetScaler Gateway for authentication, Citrix Gateway Service for StoreFront is for you.
Citrix Gateway Service handles the HDX proxy launches using a Windows-based Cloud Connector in your resource location.
Citrix Gateway Service for StoreFront supports the following use cases:
The following use cases are not supported:
- Non-HDX use cases such as RDP proxy, VPN, PC over IP (PCoIP).
Benefits
- Citrix Cloud onboarding is fast and seamless.
- Citrix DaaS customers can use their existing on-prem NetScaler Gateway URL.
- Ensures high resiliency because of the multi-cloud and multi-geo architecture of Citrix Gateway Service.
- HDX proxy performance and scale requirements are now managed by Citrix Gateway Service. They are no longer customer-managed.
Prerequisites
-
Use NetScaler 13.1 version or later. For details, refer to the NetScaler documentation.
-
Use an on-prem StoreFront version 2407 or later, with Citrix DaaS configured. For details, refer to StoreFront System requirements.
-
Onboard to Citrix Cloud and install Citrix Cloud Connector (Desktop Delivery Controller for Citrix DaaS outages. STA for ticketing).
You can use an existing Cloud Connector or deploy a new one. If your connector upgrade is disabled, contact Support to get it enabled.
For details about the Citrix Cloud Connector requirements, see Citrix Cloud Connector requirements. For details about the sizing requirements, see Size and scale considerations for Cloud Connectors.
Note:
Only a Windows-based Cloud Connector is supported. Connector Appliance is not supported.
Deploy Citrix Gateway Service for StoreFront
It is assumed that you already have an on-premises NetScaler Gateway. You can continue to use the same gateway for authentication and remote access to your StoreFront store. You can also use the same gateway to provide HDX routing to a subset of resources, such as those hosted by a Citrix DaaS deployment which Citrix Gateway Service does not support. For more details on configuring NetScaler Gateway, see the StoreFront documentation.
To configure Citrix Gateway Service for HDX routing for some or all of your resources, create a gateway in StoreFront, and then use the Optimal Gateway Routing functionality of StoreFront to configure when it needs to be used.
-
Open the StoreFront management console.
-
Create a gateway instance of type Gateway Service for HDX. For more information, see Configure Citrix Gateways.
-
In the StoreFront management console, select the store and then select the Configure Store Settings action on the right-hand panel.
-
Select the Optimal HDX Routing page. The dialog displays all the gateway instances capable of tunneling an HDX connection, including the Gateway Service gateway. For more information, see Optimal HDX Routing.
-
Select the Gateway Service for HDX gateway that you created and click Manage Delivery Controllers. Select the resource feed for your Citrix DaaS tenant.
Alternatively, if you only want to use Gateway Service for HDX for certain resource locations, click Manage Zones and provide the names of the resource locations for which the gateway instance must be used.
Resiliency with Local Host Cache (LHC)
Local Host Cache (LHC) is a functionality of Citrix DaaS that enables users to continue accessing apps and desktops when Cloud Connectors lose connectivity with Citrix Cloud.
When using Gateway Service with StoreFront, the STA ticket redemption behavior differs between working normally and being in LHC mode.
- When working normally, STA tickets are redeemed from the ticketing service hosted in Citrix Cloud.
- When in LHC mode, STA tickets are redeemed from the Cloud Connector.
Note:
Cloud Connectors must maintain connectivity with the Gateway Service in LHC mode to redeem STA tickets. Launches fail in LHC mode if connectors cannot communicate with the Gateway Service.
The following diagram illustrates how STA ticket redemption works in a Citrix Gateway Service for StoreFront deployment in a normal working scenario and when in LHC mode.
