Why are Loadbalancer.org appliances so reasonably priced?

Originally we worked with large ISP partners who needed a simple cost effective load balancer to re-brand and re-sell to their customers.
We only use Open Source technology to reduce development overheads.
We strive to keep low over heads with minimal marketing so that you get these great appliances for half the price you would expect.

Can I load balance SAP, SIEBEL, ORACLE, PEOPLESOFT, etc?

You can load balance ANY TCP or UDP packets,
but you meant to say:

Will the load balancer magically fix a poorly designed application?

No. If your application does not have a persistent backend storage device (a database) then you only get increased performance, failover will loose the session. THIS IS THE SAME FOR ALL LOAD BALANCERS - NO PERSISTENCE IN THE APPLICATION = NO SESSION FAILOVER.
Persistence by source ip address is useful for: Terminal Services, Streaming Media and HTTPS. Persistence is fully supported by every Loadbalancer.org appliance. Loadbalancer.org appliances also support cookie insertion and re-write.

Don't I need a layer 7 switch?

Loadbalancer.org appliances fully support Layer 7 switching utilising the high performance Ha-Proxy. But, a layer 7 switch is basically a proxy server. Layer 7 switching is very slow.

Instead of switching by URL just switch at layer 4 using DNS. For example instead of switching on /shop and /browse switch on shop.mysite.com and browse.myshop.com.
Don't believe the marketing hype over a very simple and slightly pointless technology.
If you want to scale out a Layer 7 solution then take a look at Willy Tarreau's excellent article.

Don't I need SSL switching or acceleration?

Loadbalancer.org appliances fully support SSL termination using Pound. This is to enable the load balancer to process SLL Layer 7 traffic including cookies etc.
If you want to scale a soloution like this you may want to invest in some cheap SLL accelerators.

If you are working at Layer 4 as recommended you don't need to worry about SSL acceleration, what the heck do you think you have a load balancer for?
Just add more SSL capable web servers.
NB. If anyone can explain what possible use SSL switching is please let us know.

Don't I need Cookie/URL/SSL persistence?

Loadbalancer.org appliances fully support Layer 7 switching and cookie persistence utilising the high performance Ha-Proxy.

But, you should never require persistence on your load balancers that's just poor design.
If your application is so poorly coded that it needs persistence then source ip persistence works fine, whereas cookie/url/SSL are client dependent.

Persistence is sensible for something like Windows Terminal Server (to keep the same session) or HTTPS (to avoid excessive re-negotiation of keys).
Remember, remember that if your REQUIRE persistence you'll get NO FAILOVER!

Don't I need GSLB (Global Server Load Balancing)?

Nice idea, shame it doesn't work. The only method that works is to use multiple DNS A records and BGP which your ISP can sort out for you.
GSLB is a marketing gimick and does not work.
Why DNS Based Global Server Load Balancing (GSLB) Doesn’t Work.
Before you use GSLB for failover have you first made your primary site indestructible? i.e.

2 x Internet feeds
2 x Switch fabrics
2 x firewalls
2 x Load balancers
3+ x Web Servers
2+ x Database Servers

Can't I just use the load balancer in Windows Advanced Server?

Um, its expensive, CPU & network intensive and doesn't even support application health checking.

Don't I need a consultant?

No. It's childs play to set up a Loadbalancer.org appliance.
NB. This is also why your consultant will try to sell you a product that requires a week long boot camp to understand how to switch it on.
If you would prefer to use a consultant just ask one of your choice to contact us directly for back up and support.

Can I have 24*7 support?

Yes, Our Premium support package is 24*7 with a 1 hour SLA.. Send an email to support@loadbalancer.org and we will endevour to answer your question as fast as we can. If you prefer you can use the  24 hour call center to do exactly the same thing.

Can I have on site 4 hour response hardware maintenance?

No. Why not buy a Hot Spare / Dev unit instead? We give a large discount on a 3rd load balancer appliance purchased at the same time. However if on an site support engineer is what you need then check out our sister company ClusterScale Ltd. They have great load balancing appliances on Dell hardware with 24*7 on-site support.

Can I have next day hardware replacement?

Yes, we can offer next day hardware replacement in America & Europe, with best effort in other locations.

Can I load balance two Internet connections?

No. That's called 'link balancing' or'WAN balancing' .. try Riverbed.
