We took the final barrier for you, now you just have to plug it in and power it up…
Ever since the introduction of open source, there has been one common challenge that binds them all..
the lack of turn-key open source appliances,so if you like the software you will have to build your own server, firewall, phone system or whatever open source appliance you require.

In the end that is where the real cost is as you need to find out where to buy quality hardware, test and install the software on it…
And then? Well most of the time things aren’t going as planned.

So when we introduced our first appliances we had two things in mind:

With our OPN line appliances we added another dimension to this philosophy
and for the first time open source can finally win the battle from the commercial competitors.

Take a look for yourself and be amazed!

Zen Load Balancer

Zen load balancer is a free, open source customized distribution of Debian tailored for use as a load balancer.
Load balancing is a technique to distribute workload evenly across two or more computers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilization, maximize throughput, minimize response time, and avoid overload. Using multiple components with load balancing, instead of a single component, may increase reliability through redundancy. The load balancing service is usually provided by a dedicated program or hardware device .
It is commonly used to mediate internal communications in computer clusters, especially high-availability clusters. If the load is more on a server, then the secondary server takes some load while the other is still processing requests.

Currently all OPNzen appliances are delivered with version v2rc3.1 of the software.

Zen load balancer includes many features available in expensive commercial products, but remains easy to configure via a webinterface. The following is a list available in the current version:
