Citrix Virtual Apps and Desktops service

Limits

The values in this article indicate the limits of a single Citrix Virtual Apps and Desktops service instance. When the number of concurrent users exceeds 100,000, Citrix can scale and combine multiple Citrix Virtual Apps and Desktops service 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.
