Title: GIR with F5 Load Balancer
Post by: raza990 on July 30, 2018, 04:26:03 AM: Hi Experts,

Anybody here deploy GIR with F5 LB instead Apache ?

We do have F5, and want to utilize F5 for GIR LB. But I cant find any documentation of Genesys where they say how it will be deploy or work like SIP-F5 document have. From Genesys, Its confirmed that we can use F5 for GIR.

Anybody here have experience of using F5 with GIR, and can share the bottle neck or challenges of using F5 for GIR LB ?

What I understood is that just configure both server physical IP with VIP but the important thing is to configure cookies or session identifiers. Some applications require stickiness and some cookies which I can take reference from GIR Solution Deployment Documentation.

The other components only need to have a simple load balancing, when for example a POST is done, it points to the F5 and it redirects the POST to the component. The F5 listen in one port for each "cluster" of component (also it can be recognized by the first part of the URL, for example http://IP/component1): one port for WebDAV, one port for RPS, one port for Interaction Receiver, and the mentioned before that needs extra configuration. Then the F5 simply do a round robin between the members (ip:port of the application), because them don't requires stickyness.

The RCS and RWS "extra" configuration of httpd load balancer is (red):
# Web Services
<Proxy balancer://htcc>
BalancerMember http://htcc1:8080 route=HTCC1
BalancerMember http://htcc2:8080 route=HTCC2
BalancerMember http://htcc3:8080 route=HTCC3
[color=red]Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED
ProxySet stickysession=ROUTEID[/color]
</Proxy>
ProxyPass /api balancer://htcc/api
ProxyPass /internal-api balancer://htcc/internal-api
ProxyPass /ui balancer://htcc/ui

# RCS
<Proxy balancer://rcs>
BalancerMember http://rcs1:8008 [color=red]disablereuse=On connectiontimeout=10000ms route=RCS1_Application_Name[/color]
BalancerMember http://rcs2:8008 [color=red]disablereuse=On connectiontimeout=10000ms route=RCS2_Application_Name[/color]
[color=red]ProxySet stickysession=JSESSIONID[/color]
</Proxy>
ProxyPass /rcs balancer://rcs/rcs

You'll need to "translate" this extra configuration to F5 "language". I've never done it, but httpd and F5 are very used so I think there is a lot of information
