Limits
The values in this article indicate the limits of a single Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) instance. These limits are extensively tested by Citrix and recommended for the best end user and admin experience. These are soft limits and not technically enforced (except 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 theWorkspace Environment Management serviceorActive Directory Group Policy Objects (GPOs).
Resource | Limit |
---|---|
Active Directory domains | 85 |
Application folders | 1,000 |
Application Groups | 250 |
Applications | 5,000 |
Catalogs | 1,000 |
Delivery Groups | 1,000 |
Host connections | 200 |
Resource locations | 85 |
Manage console (Full Configuration) policies | 200 |
Tags | 500 |
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 | 20,000 |
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, seeSize 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 Amazon Web Services account per region | 1,500 |
VDAs per Google Cloud Platform project | 3,000 |
VDAs per Microsoft Azure subscription | 2,500 |
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 (Full Configuration) cloud administrators | 100 |
Concurrent Manage (Full Configuration) 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 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.
