Re: [nznog] Load balance appliances

Hi Jodi, No doubt with <= 2Gbps of vanilla HTTP/S you could roll your own with linux, a modern Intel with AES-NI and script glue. What you get with appliances (F5 in particular, but other vendors as well) is the ability to do crazy wonderful in a predictable and simple way. An iRule to remove a null value ( : ) HTTP header created by a brain-dead browser from the dumbphone days; or timestamping the first request, first response, final packet and final browser load-time (network, server or client problem); spring to mind. With that in mind, I suggest you look at load balancers with the corner case problems you want to solve, and the vendor's solutions to them. Thanks, Jed. Sent from a dumbphone with a big screen.

Many thanks to all who've replied

To be honest I hadn't considered SSL until now as many of our sites are still vanilla http - however with the way things are moving we should probably plan for it

To narrow things down at this stage we're currently sitting at ~50-100meg traffic with ~2000 active sessions. However we want to plan ahead and install a decent infrastructure now, which can be easily scaled up when/if required

cheers JT

Hi Jodi,

If it’s web traffic, safe to confirm SSL too?

If so; and it’s decent volumes, ignore the base model F5s and A10s - the next step up have hardware-based SSL offload, which increases capacity markedly. We needed the A10 3030s, as running campaign sites means we can get 10,000 visitors wanting to establish SSL sessions in a very short space of time, and moving ~10Gbit/s of traffic.

As others have pointed out - a more robust use case scenario would help narrow down the choices.

Cheers,

Karl

 Hi Jodi, The old Alteons are excellent :) We run F5 virtuals here (they cluster well) and a combination of virtuals + physical F5 units in AU. Have been testing KEMP Technologies as well - they have an excellent Aussie team based in SG.

Last ones I had anything to do with were the Alteon Ace Directors going back 7-8 yrs so am a little out of touch with whats in use today.
