FAQ for licensing

How is Citrix Virtual Apps and Desktops licensed?

The Citrix Virtual Apps and Desktops licensing offers user/device and concurrent license models.

User/device:

The flexible user/device model aligns with:

  • Enterprise-wide desktop usage.
  • Underlying Microsoft desktop virtualization licensing.
  • Concurrent licensing for customers with users needing only occasional access to their virtual desktops and apps.

User/device licensing gives users access to their virtual desktops and apps from an unlimited number of devices. Device licenses give an unlimited number of user’s access to their virtual desktops and apps from a single device. This approach provides you with maximum flexibility and improves alignment with Microsoft desktop virtualization licensing.

Important:

You can’t manually assign licenses to a user or device. The License Server or cloud service assigns licenses. With user/device licensing, once a license is assigned it can’t be assigned to another user until after 90 days of inactivity.

Concurrent:

Concurrent licenses allow one connection to an unlimited number of virtual apps and desktops for any user and any device. A license is consumed only during an active session. If the session disconnects or is terminated, the license is checked back into the pool.

For more information about user/device licensing, see User/device licenses and concurrent licenses see, Concurrent licenses.

Is it possible to try Citrix Virtual Apps and Desktops before purchasing licenses?

Yes. You can download the Citrix Virtual Apps and Desktops software and run it in trial mode. Trial mode lets you use Citrix Virtual Apps and Desktops on-premises for 30 days, for 10 connections, without a license. To continue using the product at the end of the trial period, download a free EVAL license (99 users for 90 days) or purchase Citrix Virtual Apps and Desktops licenses.

Citrix Virtual Apps and Desktops Services for Citrix Cloud is available for trial service based on approval. Check with your Citrix representative for further details.

How does Citrix define concurrency for Citrix Virtual Apps and Desktops?

The Citrix Virtual Apps and Desktops concurrent model allows one connection to an unlimited number of virtual apps and desktops for any user and any device. A license is consumed only during an active session. If the session disconnects or is terminated, the license is checked back into the pool for reissue.

How does Citrix assign licenses to users in the user/device licensing model?

With the user/device license model, the License Server assigns the license to a unique user ID. It allows that single user unlimited connections from unlimited devices. If a user connects to a desktop or device, the user requires one license assigned to that user to access a virtual desktop or application. The License Server or cloud service assigns the license. You can’t assign these licenses manually. The license is assigned to the user, not the shared device. Once a license is assigned, it can’t be assigned to another user until after 90 days of inactivity.

How does Citrix define a licensed device in the user/device licensing model?

A licensed device requires a unique endpoint device ID. Under the user/device model, a device is any piece of equipment that you authorized for use by any individuals to access instances of Citrix Virtual Apps and Desktops. For a shared device, a single Citrix Virtual Apps and Desktops user/device license can support multiple users that share the device. For example, a shared device can be a classroom workstation or a clinical workstation in a hospital.

Can I convert my Citrix Virtual Desktops Standard Edition concurrent licenses to the user/device model?

You cannot convert Citrix Virtual Desktops Standard Edition concurrent licenses to Citrix Virtual Desktops Standard Edition user/device licenses. Similarly, you cannot convert Citrix Virtual Desktops Standard Edition user/device licenses to Citrix Virtual Desktops Standard Edition concurrent licenses.

If you have Citrix Virtual Desktops Standard Edition concurrent licenses and you want the user/device license model, upgrade to either Citrix Virtual Apps and Desktops Advanced or Premium Edition.

How does concurrent licensing work differently from user/device licensing?

We base concurrent licensing on concurrent device connections. A concurrent license is in use only when a device has established an active connection. Once the connection ends, the concurrent license returns to the license pool for immediate use. We recommend this licensing model for occasional usage. User/device licenses are leased for a period and are not available for other users until the lease expires.

Under the user/device model, can we assign licenses to both users and devices in the same enterprise?

Yes. Both types can be present in the same enterprise. The License Server optimally assigns licenses to users or devices based on usage. You can’t assign these licenses manually.

How do I decide how many users or devices to license?

Assess the use case requirements to determine the appropriate number of licenses. User/device licensing enables unlimited access to unlimited virtual desktops and virtual apps from an unlimited number of devices. Concurrent licensing enables unlimited access to unlimited virtual desktops and virtual apps from a single device that an unlimited number of users can use. Consider the following formula:

(Number of total users) – (number of users that only access exclusively
 with shared devices) + (number shared devices) = total number
 of licenses to buy.

For example, there are 1000 total users at the hospital. If 700 of them access only
Citrix Virtual Desktops from 300 shared devices in the hospital, the number of
licenses to purchase is 1000 – 700 + 300 = 600 licenses.

Under the user/device model, what is the maximum number of devices a licensed user can use to connect to my environment?

Each licensed user is entitled to use an unlimited number of connected or offline devices.

Under the user/device model, what is the maximum number of users who can access a licensed device?

Each licensed device can service an unlimited number of users within an organization.

Under the user/device model, what is the maximum number of virtual desktops or Secure Browser web applications a licensed user can consume at any given time?

Each licensed user can connect to an unlimited number of virtual desktops or web applications.

What is the maximum number of virtual applications a licensed user can consume at any given time?

Each licensed user can connect to an unlimited number of virtual applications.

What happens if a licensed user leaves my organization?

When an existing licensed user leaves your organization, you can release the departing user’s license without notifying Citrix. Use the udadmin utility to release the license. If you don’t release the license, the License Server automatically releases any license after 90 days of inactivity. This information is subject to terms specified in the EULA.

What happens if a licensed user is absent for a protracted period?

If an existing licensed user is absent for a protracted period, you can release the license without notifying Citrix, so that it becomes available for reassignment. Use the udadmin utility to release the license.

What happens if we replace a licensed device in my organization?

If you replace an existing licensed device, you can release the license without notifying Citrix so that it becomes available for reassignment. Use the udadmin utility to release the license.

What happens if a licensed device is out of service for an extended period?

When an existing licensed device is out of service for an extended period, you can release the license without notifying Citrix, so that it becomes available for reassignment. Use the udadmin utility to release the licenses. If you don’t release the license, the License Server automatically releases any license after 90 days of inactivity. This information is subject to terms specified in the EULA.

Can I switch user licenses to device licenses and conversely after I’ve assigned the licenses to a device or user?

Yes. This change happens automatically. The License Server assigns licenses to either users or devices based on usage patterns. If usage patterns change, the License Server might switch the assignment based on the new usage. The License Server always assigns licenses in the most economical fashion for the customer. Also, the License Server monitors licenses to identify unused licenses after their 90-day assignment period. You can reassign licenses identified as unused after the 90-day assignment period to other users or devices.

Under the concurrent model, what is the maximum number of virtual desktops a Citrix Virtual Apps and Desktops licensed user can consume at any given time?

An endpoint can service many users and allows for unlimited connections.

Can I purchase Citrix Virtual Apps and Desktops licenses to increase the number of licensed users/devices in my existing Citrix Virtual Apps and Desktop environment?

Yes. You can purchase Citrix Virtual Apps and Desktop licenses to increase the number of licensed users/devices in your existing Citrix Virtual Apps and Desktop environment.

Can I deploy concurrent licenses from a previous version of Citrix Virtual Apps and Desktops and new user/device or concurrent licenses to a single License Server?

Yes. You can continue to use the same License Server to support user/device or concurrent licensed deployments.

Can I deploy concurrent licenses and user/device or concurrent licenses to a single License Server?

Yes. You can continue to use the same License Server to support concurrent and user/device or concurrent licensed deployments.

Can I deploy multiple editions of Citrix Virtual Apps and Desktops licenses on a common License Server?

Yes. The License Server manages licenses for both Citrix Virtual Apps and Desktops simultaneously. We recommend that you install the latest License Server version. If you are unsure if your License Server version is current, verify it by comparing your version with the number on the Citrix downloads site.

Can a single site use both Citrix Virtual Apps and Citrix Virtual Apps and Desktops licenses?

Depending on the version, a single Citrix Virtual Apps or Citrix Virtual Apps and Desktops site can support both licensing models - user/device or concurrent. A single Citrix Virtual Apps or Citrix Virtual Apps and Desktops site can support only one edition. For more information, see Multi-type licensing.

The minimum versions that support multi-type licensing are XenApp and XenDesktop 7.15 Long Term Service Release (LTSR) and Citrix Virtual Apps and Desktops 7 1808.

Can I select Citrix Virtual Apps concurrent as a product model if I have Citrix Virtual Apps and Desktops user/device or Citrix Virtual Apps and Desktops concurrent licenses installed on the License Server?

If you use Citrix Virtual Apps as a feature of Citrix Virtual Apps and Desktops Advanced or Premium Edition, your Citrix Virtual Apps license model is the same as your Advanced or Premium Edition of Citrix Virtual Apps and Desktops. If you have purchased Citrix Virtual Apps and Desktops, configure your licensing as Citrix Virtual Apps and Desktops even if you plan to use only the Citrix Virtual Apps functionality. Select Citrix Virtual Apps as a product model only if you have Citrix Virtual Apps concurrent standalone licenses installed on the License Server.

Overdraft licenses

This section answers your questions about overdraft licenses.

How do I get overdraft licenses? License overdraft is included in all user/device licenses. When you purchase user/device licenses, you receive a 10% overdraft. The overdraft becomes available after you allocate all your purchased and evaluation licenses. We offer the overdraft feature as a convenience, not as a license entitlement. If you use the overdraft licenses often, we suggest you purchase more licenses.

How can I identify a license overdraft? You can view usage information, including the number of licenses in overdraft in the Citrix Licensing Manager. Studio also contains overdraft usage information.

What happens when an overdraft license is consumed? A license is assigned from your installed licenses to enable access to your Citrix Virtual Apps and Desktops environment. This overdraft license provides as much access and functionality as your other licenses.

Can I get an alert when my overdraft licenses are consumed? Currently, there are no specific alerts provided when overdraft licenses are consumed.

How long can an overdraft license be consumed? You must purchase any overdraft licenses used within 30 days of the first use.
