The adjustment of a number of application launch endpoint servers that may be used to service incoming connection requests. Application launch endpoints are entities, such as running code, that may be used to launch other applications. Examples of endpoints include virtual machines or sessions in a session management server. The system load associated with the incoming connection rate and number of users is monitored. In response, an add threshold and a perhaps a remove threshold is calculated. If the system load rises above the add threshold, application launch endpoint server(s) are added to the set of endpoints that can handle incoming connection requests. If the system load falls below the remove threshold, application launch endpoint server(s) are removed from to the set of endpoints. The add and remove thresholds may be calculated per tenant, and adjusted based on tenant behavior.
