Load Balancer info required

Hello Experts,

We are looking for the open source load balancing solution for our Apache Web Servers.
Can someone please suggest best open source load balancer for Apache Web Server.

Regards

Hi sdbhabal and welcome to WebmasterWorld [webmasterworld.com]

Thank you.

Do you mean , integrated to Apache, or a front end ?

In Apache, you have this : [httpd.apache.org...]

If this is a front end, I would use nginx

[sdbhabal]

I mean to say separate layer of load balancer like HAProxy.

It's like asking what the best operating system is. There isn't one, it just depends on what you're looking for. HAproxy and nginx are popular choices, so you'll find stability with those, as well as plenty of documentation.

Basically my requirement is whether the outgoing traffic from backend servers under the LB can translate to a unique public IP instead of firewall IP.

Any thought on this ?

Basically my requirement is whether the outgoing traffic from backend servers under the LB can translate to a unique public IP instead of firewall IP.

I'm not sure I understand what you're saying here.

[sdbhabal]

Let say for example.

Below is my setup:
LB : 192.168.1.1
Web Node 1 : 192.168.1.2
Web Node 2 : 192.168.1.3
On firewall, I have one public IP associated (NATed) to LB IP.

Whenever someone from internet access public IP, traffic then routed to LB & then it is distributed to underneath Nodes. This is I am talking about incoming traffic.

What I wanted to achieve is, whenever there is a outbound traffic, meaning whenever my nodes initiate any traffic to the internet or for the outside of my network.
That traffic should take my LB public IP to go out & not my default firewall WAN IP.

Please let me know if anything unclear here.

[robzilla]

If that traffic is not in response to an incoming request, then I guess you'd have to set up a proxy (forward as opposed to reverse) on the load balancer and skip the firewall to achieve that. I know nginx can do that, although it's not necessarily built for it. You can use proxy_pass to pass on any traffic. That probably goes for HAproxy too, but I've never used it.

Okies, let me try this & come up with some output.
Thanks.
