Summary
We have performed a complete cluster installation. It is not as difficult as it seems. Once
we have fixed the variables and decided what hardware requirement is needed, it is just a
matter of running a shell script that does everything. Multiple data center setups are equally
simple. Many variables depend on your particular use case, but if you do not have a partic-
ular specification in mind, go with the suggested ones or the default one. They are gener-
ally good.
Setting up a cluster is probably a one-time task for an organization. It is likely that your
first cluster will be just a couple of nodes. It is equally likely that you will stick with that
cluster for first production, or at least till you plan to make the first release with Cassandra
in your system. In production, the first couple of things that come to everyone's mind are
questions such as the software is tuned to perform its best? What happens when things start
to break? What if we needed to ramp up the servers? How safe is our data? Chances are
that you will be expected to answer these questions. Therefore, you should know the an-
swers before these questions are directed to you. The next few chapters are about all these
questions.
