Software Load Balancers | mod_proxy_balancer and Varnish

[Anurag Kapur <anuragkapur@xxxxxxxxx>]

Hi,

Apologies in advance for a fairly high level question which may not be the norm of this users group.

I am trying to understand options and eventually choose a software load balancer for a project I am working on. I am specifically interested in the capabilities of two options - Apache HTTPD mod_proxy_balancer and Varnish (https://www.varnish-cache.org/trac/wiki/LoadBalancing) from the following perspectives:

1. Feature set supported like - session stickyness, failover from one node to another in the load balancer farm etc

2. Performance/throughput

3. Stability of the solution

4. Ease of use or time required to setup for typical http(s) load balancing use cases

I did try googling for information for a couple of hours but was not successful in finding a good comparison. So I am looking at your experience to get some pointers.

Any help would be highly appreciated.

Kind Regards

Anurag
