Horizon Access Point limits
A Horizon Access Point has the same connection limitations as Horizon Connection and Security Servers, which means it can support up to 2,000 simultaneous Horizon client connections. Despite this limit, it is important to remember that multiple Access Point appliances should be deployed to ensure both capacity and availability requirements are met.
Each Horizon Access Point is a stand-alone instance; therefore, there is no specific guidance with regard to how many can be deployed. However, unlike a Horizon Security Server, a Horizon Access Point can be used with multiple Connection Servers at once, although those Connection Servers must be placed behind a load balancer.
