This chapter highlights the most important aspects of deploying a Cassandra cluster into the production environment. Cassandra can be taught to understand the physical location of the nodes in the cluster in order to intelligently manage its availability, scalability and performance. We deployed the Stock Screener Application to the production environment, though the scale is small. It is also valuable for us to learn how to migrate legacy data from a non-production environment.

We then learned the basics of monitoring and performance tuning which are a must for a live running system. If you have experience in deploying other database and system, you may well appreciate the neatness and simplicity of Cassandra.

In the next chapter, we will have a look at the supplementary information pertinent to application design and development. We will also summarize of the essence of each chapter.
