In this chapter, we learned how and when big data can be processed in the cloud, right from configuration, collection, and transformation to the analysis of data.

Currently, Hadoop in the cloud is not used much in banks due to a few concerns about data security and performance. However, that is debatable.

For the rest of this book, I will discuss projects using on-premise Hadoop implementations only.

In the next chapter, I will pick up a medium-scale on-premise Hadoop project and see it in a little more detail.
