You can choose between two broker types for connecting to Amazon WorkSpaces with the HP Anyware Client on IGEL OS.  

PCoIP Broker

PCoIP broker is a resource manager that dynamically assigns host PCs to zero clients based on the identity of the user established from the zero client. Connection brokers are also used to allocate a pool of hosts to a group of zero clients in a PCoIP deployment. If the zero clients are configured to always connect to the same host (i.e., a static one-to-one pairing), then a connection broker is not required.

Direct Hardhost

A direct hardhost is a direct connection between a zero client and a remote workstation containing a PCoIP Remote Workstation Card. You can specify a host's DNS name or IP address, or you can configure clients to use the Service Location Protocol (SLP) to discover a host. You can also configure clients to automatically reconnect to a host when a session is lost.
