Understanding F5 LTM in front of a Citrix XenApp

Posted By Roumen on 10/31/2012 06:54 AM

 

Hi everybody,

 

I have some doubts after reading quickly the whitepapers and deployment guides of APM and LTM with XenApp.

 

Doubts:

 

1.- Is Big IP LTM able to load balance ICA traffic connections across a pool of XenApp Application servers or this function is performed by Citrix XML Brokers Service?

 

No, ICA traffic is being load-balanced by the Zone Data Collector(and is relayed to the client via Web Interface/XML Broker combo.

 

As I understand Big IP LTM only load balances connections to Web Interface and XML Brokers.

 

Correct.

 

2.- Can Big IP LTM act as a proxy server for ICA traffic connections? I don't want clients to establish direct connections to the XenApp Application servers.

 

Secure ICA Proxy is the function of the APM module. LTM will only load-balance connections to Web Interface and XML Brokers, APM will act as a proxy/pre-authentication mechanism for ICA traffic.

 

Thanks very much in advance.

 

Kind regards,

 

Roumen
