Citrix DaaS

Limits

December 11, 2024

Contributed by:

The values in this article indicate the limits of a single Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) instance. Citrix has extensively tested these limits and recommends for the best end user and admin experience. These limits are soft limits and not technically enforced (except for the number of Active Directory domains and the total number of VDAs per resource location). When the number of concurrent users exceeds 125,000, Citrix can scale and combine multiple Citrix DaaS instances, to deliver a unified experience at any scale.

The information in this article is dynamic. Check back frequently for updates. If you have current requirements that the published limits do not address, contact your Citrix representative for assistance as early as possible.

Configuration limits

If policies exceed the limit, Citrix recommends using the Workspace Environment Management service or Active Directory Group Policy Objects (GPOs).

Resource	Limit
Active Directory domains (hard limit)	100
Application folders	1,000
Application Groups	250
Applications	5,000
Catalogs	2,000
Delivery Groups	2,000
Host connections	200
Resource locations	200
Policies (Studio)	200
Tags	10,000
VDAs	100,000

Resource location limits

The following table lists the limits for each resource location.

If your requirements exceed these limits, Citrix recommends using additional resource locations.

Resource	Limit
Total VDAs (hard limit)	10,000
Total sessions	25,000
Active Directory domains	1
Host connections	40

Citrix Cloud Connectors are assigned to resource locations and link workloads to Citrix DaaS. For information about Cloud Connector limits, see Size and scale considerations for Cloud Connectors.

Provisioning limits

The provisioning limits in the following table are the Citrix recommended maximums for a single public provider subscription.

You are likely to reach quota limits from your public cloud vendor at lower levels. In such cases, contact the vendor to raise your subscription quota. For larger-scale deployments, Citrix recommends a hub-and-spoke model, where VDAs are distributed across multiple subscriptions and host connections.

For more information, see the following reference architectures:

Resource	Limit
VDAs per AWS account per region	3,000
VDAs per Google Cloud Platform project	3,000
VDA per Microsoft Azure subscription per region	5,000

Note:

The limits are Citrix recommended.

Usage limits

For information about administrator roles and the differences between them, see:

Resource	Limit
Concurrent Monitor (Director) full administrators	40
Concurrent Monitor (Director) help desk administrators	200
Concurrent Monitor (Director) session administrators	50
Concurrent Manage (Studio) cloud administrators	100
Concurrent Manage (Studio) help desk administrators	60
Concurrent end users	125,000
Resources published to a single user	250
Session launches per minute	3,000

Monitor (Director) supports the aggregation of up to four Citrix DaaS tenants (spokes) under a single tenant (hub).
A help desk administrator on the hub instance can monitor and troubleshoot users, machines, endpoints, and transactions from all aggregated instances (hub and spokes) as per the Delegated Administration configuration on the specific instance.
The number of concurrent administrators per Citrix DaaS instance is as per the Usage Limits table.
