Those to statements are at odds with each other, at least based on
everyone I've ever talked to in a commercial setting. People will use
terms like 'replication', 'HA' or 'clustering' fairly interchangably.
Usually what these folks want is some kind of high-availability
solution. A few are more concerned with scalability. Sometimes it's a
combination of both. That's why I think it's good for the chapter to
deal with both aspects of this.
