Service continuity removes or minimizes dependence on the availability of components involved in the connection process. Users can launch their Citrix DaaS apps and desktops regardless of the cloud services health status.
Service continuity allows users to connect to their DaaS apps and desktops during outages, as long as the user device maintains a network connection to a resource location. Users can connect to DaaS apps and desktops during outages in Citrix Cloud components or in public and private clouds. Users can connect directly to the resource location or through the Citrix Gateway Service.
Service continuity improves the visual representation of published resources during outages by using Progressive Web Apps service worker technology to cache resources in the user interface.
Service continuity uses Workspace connection leases to allow users to access apps and desktops during outages. Workspace connection leases are long-lived authorization tokens. Workspace connection lease files are securely cached on the user device.
When a user signs in to Citrix Workspace, Workspace connection lease files are saved to the user profile for each resource published to the user.
Service continuity lets users access apps and desktops during an outage even if the user has never launched an app or desktop before. Workspace connection lease files are signed and encrypted and are associated with the user and the user device. When service continuity is enabled, a Workspace connection lease allows users to access apps and desktops for seven days by default. You can configure Workspace connection leases to allow access for up to 30 days. When users exit Citrix Workspace app, Citrix Workspace app closes but the Workspace connection leases are retained.
Users exit the Citrix Workspace app by right-clicking its icon in the system tray or by restarting the user device. You can configure service continuity to delete or retain Workspace connection leases when users sign out of Citrix Workspace during an outage.
By default, Workspace connection leases are deleted from user devices when users sign out during an outage. Service continuity is supported for double hop scenarios when Citrix Workspace app is installed on a virtual desktop. For an in-depth technical article about Citrix Cloud resiliency features, including service continuity, see Citrix Cloud Resiliency. Otherwise, that deprecated feature is unrelated to service continuity.
To access resources during an outage, users must sign in to Citrix Workspace before the outage occurs. When you enable service continuity, users must perform the following steps on their devices:. When a user signs into Citrix Workspace for the first time, service continuity downloads Workspace connection leases to the user device. For some outages, users continue accessing their DaaS with no change to their user experience.
For other outages, user might see a change in how Workspace appears or be prompted to take some action. This table summarizes how service continuity helps users access apps and desktops during different types of outages. Some virtual apps and desktop may still be available. During an outage in the identity provider for workspace authentication, users might be unable to sign in to Citrix Workspace through the Workspace sign-in page.
After 40 seconds, this message appears at the top of the Citrix Workspace home page. Afterward, the Citrix Workspace home page appears. Users then access resources as they would during a Citrix Workspace outage.
Regardless of the type of outage, users can continue to access resources if they exit and relaunch Citrix Workspace app. Users can restart their user devices without losing access to resources. In the default configuration of service continuity, users lose access to their resources if they sign out of Citrix Workspace. If you want users to retain access to their resources after signing out, specify that Workspace connection leases are kept when users sign out. See Configure service continuity.
Before accessing an app or desktop, users must reauthenticate to the VDA. Citrix Workspace is configured for single sign-on during installation by selecting the single sign-on box. Citrix Workspace app is configured with domain pass-through authentication. Users can access any available resource during a Citrix Workspace outage without entering their credentials.
For information about configuring domain pass-through authentication for Citrix Workspace app for Windows, see Configure single sign-on using the graphical user interface , found in the Authenticate documentation.
Session sharing is enabled. Users can access apps or desktops hosted on the same VDA after they provide their credentials for one resource on that VDA. Session sharing is configured for the application group containing the resource on the VDA.
For information about configuring application groups, see Create application groups. In all other configurations, users are prompted to reenter their AD credentials at the VDA before accessing resources.
Using Citrix Gateway as a Workspace authentication method is supported. For information on installing Citrix Workspace app for Linux, including information about installing the app for use with service continuity, see Citrix Workspace app for Linux. Make sure script execution is enabled by setting the Execution Policy to remotedSigned value appropriate for your environment. Other script execution privileges can also work, like Default or AllSigned. Configure your firewall to allow this connection.
For more information about app protection policies, see App protection. The Windows Logon user interface that prompts users to reauthenticate on the VDA does not support local keyboard language mapping. To allow users to reauthenticate during an outage if they have local keyboard language mapping on their devices, preload the keyboard layouts these users require. Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Use the Registry Editor at your own risk.
Be sure to back up the registry before you edit it. For a list of keyboard identifiers associated with keyboard languages, see Keyboard Identifiers and Input Method Editors for Windows. This configuration is the default setting. If that connection fails Gateway Service is used as fallback. Allow internal users to bypass the gateway and connect directly to the resource location reduces latency internal network traffic.
This PowerShell command is similar to Direct Workload Connection in that it optimizes connectivity to workspaces by allowing internal users to bypass the gateway and connect to VDAs directly.
When service continuity is enabled, Direct Workload Connection is not available during outages. When you enable service continuity, it is enabled for all delivery groups in your site. To disable service continuity for a delivery group, use the following PowerShell command:. Replace deliverygroup with the name of the delivery group. By default, Workspace connection leases are deleted from the user device if the user signs out of Citrix Workspace during an outage.
If you want Workspace connection leases to remain on user devices after users sign out, use the following PowerShell command:. Citrix Workspace generates a unique ICA file each time a user selects a virtual app or desktop icon.
The tickets in each ICA file expire after about 90 seconds. Citrix Workspace generates ICA files when users launch virtual apps and desktops regardless of whether service continuity is enabled.
