This chapter has introduced the Heartbeat package and the theory behind properly deploying it. To ensure client computers always have access to a resource, use the Heartbeat package to make the resource highly available. A highly available resource does not fail even if the computer it is running on crashes.
In Part III of this book I'll describe how to make the cluster load-balancing resource highly available. A cluster load-balancing resource that is highly available is the cornerstone of a cluster that is able to support your enterprise.
In the next few chapters I'll focus some more on how to properly use the Heartbeat package and avoid the typical pitfalls you are likely to encounter when trying to make a resource highly available.
