Plan your StoreFront deployment 编辑

StoreFront employs Microsoft .NET technology running on Microsoft Internet Information Services (IIS) to provide enterprise app stores that aggregate resources and make them available to users. StoreFront integrates with your Citrix Virtual Apps and Desktops deployments, providing users with a single, self-service access point for their desktops and applications.

StoreFront comprises the following core components:

• The authentication service authenticates users to Microsoft Active Directory, ensuring that users do not need to log on again to access their desktops and applications. For more information, see User authentication.
• Stores enumerate and aggregate desktops and applications from Citrix Virtual Apps and Desktops. Users access stores through Citrix Workspace app, Citrix Receiver for Web sites, and XenApp Services URLs. For more information, see User access options.
• The subscription store service records details of users’ application subscriptions and updates their devices to ensure a consistent roaming experience. For more information about enhancing the experience for your users, see Optimize the user experience.

StoreFront can be configured either on a single server or as a multiple server deployment. Multiple server deployments not only provide additional capacity, but also greater availability. The modular architecture of StoreFront ensures that configuration information and details of users’ application subscriptions are stored on and replicated between all the servers in a server group. This means that if a StoreFront server becomes unavailable for any reason, users can continue to access their stores using the remaining servers. Meanwhile, the configuration and subscription data on the failed server are automatically updated when it reconnects to the server group. Subscription data is updated when the server comes back online but you must propagate configuration changes if any were missed by the server while offline. In the event of a hardware failure that requires replacement of the server, you can install StoreFront on a new server and add it to the existing server group. The new server is automatically configured and updated with users’ application subscriptions when it joins the server group.

Load balancing

For multiple server deployments, external load balancing through, for example, Citrix ADC or Windows Network Load Balancing is required. Configure the load balancing environment for failover between servers to provide a fault-tolerant deployment. For more information about load balancing with Citrix ADC , see Load Balancing. For more information about Windows Network Load Balancing, see https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831698(v=ws.11).

Active load balancing of requests sent from StoreFront to Citrix Virtual Desktops sites and Citrix Virtual Apps farms is recommended for deployments with thousands of users or where high loads occur, such as when a large number of users log on over a short period of time. Use a load balancer with built-in XML monitors and session persistency, such as Citrix ADC .

If you deploy SSL-terminating load balancer or if you need to troubleshoot, you can use the PowerShell cmdlet Set-STFWebReceiverCommunication.

Syntax:

Set-STFWebReceiverCommunication [-WebReceiverService] <WebReceiverService> [[-Loopback] <On | Off | OnUsingHttp>] [[-LoopbackPortUsingHttp] <Int32>]
