In every high availability solution, as alluded to in Chapter 1, you must adhere to some fundamentals; otherwise, achieving the availability you need will be difficult. Even if you are in an IT shop or department that takes care of many of the basics listed in this chapter, you should still find a few nuggets of information here...or you might be bored. Either way, it would be inappropriate for a book on high availability to ignore the fundamentals.
This chapter addresses matters that relate to both the human and technological factors of the high availability equation. It includes such topics as data center best practices, staffing, service level agreements (SLAs), and change management.
