This chapter was about setting up Hadoop, ZooKeeper, and Accumulo on four different cloud platforms. There is a difference between those cloud platforms, but the steps required to set up an Accumulo cluster are very similar, meaning the only difference is the scripts used to automate the process. Even for Windows Azure, writing scripts for Windows or Linux is an easy task and is well documented.
In the next chapter, the focus is going to be on performance and how the optimal Hadoop cluster is configured, how much memory we really need, and CPU. Finally, we will look at configuring Accumulo systems to get the best performance.
