Chapter 23. High-Availability Systems


High availability is strongly related to security. If a system is not secure, it can hardly be considered a high-availability system as long as it is connected to a network. I want to mention this at the beginning of this chapter because it is an important point.

In this chapter you will see how high-availability systems can be designed and built. This chapter is a brief insight into the world of high availability, and the expertise you gain will help you to build more reliable systems.
