Workspace Environment Management (WEM) service is designed for large-scale enterprise deployments. On the server side, WEM service monitors the communication flow between front-end and back-end components, and scales up or down dynamically based on data in transit.

When evaluating WEM service for sizing and scalability, consider the following limits. The values in this article indicate the limits of a single WEM service instance.

Usage limits

The following table lists the usage limits.

Resource Limit
Concurrent full administration connections 5
End-user connections for every Citrix Cloud Connector 10,000 end users (machine specification: 4 vCPUs, 8 GB RAM, and 80 GB of available disk space)
WEM agent connections 100,000


To ensure high availability, we recommend at least two Cloud Connectors in each resource location. The WEM agent balances the load among Cloud Connectors automatically. If the Citrix Cloud Connectors in place are not for WEM service only, consider deploying additional Cloud Connectors. For information about Cloud Connectors, see Citrix Cloud Connector.
