Who's it for?

When considering Ubuntu 8.10 as a server one can not overlook the cost. What Ubuntu server 8.10 does is empower an IT department who is short on budget, but long on needs.

What's wrong?

One of the issues plaguing Ubuntu on the enterprise level is high availability. The reason this is often considered a problem is, out of the box, Ubuntu Server doesn't include some of the tools necessary for redundancy or high availability. However, this really doesn't have to be an issue.

Installing the heartbeat package is as simple as issuing sudo apt-get install heartbeat. All dependencies will be installed and heartbeat will be ready to configure. Of course heartbeat is a cluster-aware package so more than one server will need to be up and running for this to work.

So the myth that Ubuntu server can not do high availability is just that — a myth. To state that "out of the box Ubuntu Server 8.10 can not handle high availability" would be closer to the truth. It requires some further installation and configuration.
