Limits

This article lists the limits for various resources in a Citrix Virtual Apps and Desktops service deployment.

Machine Creation Services (MCS) limits

The MCS limits in the following table are the 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.
