Summary

This chapter is an introductory chapter for Elastic Stack and its components. We learned about how it progressed, what was changed, what was introduced, and how it became Elastic Stack from ELK stack. We got to know about a few of the case studies where these components helped organizations to meet their requirements.

Later in the chapter, we set up Elasticsearch, Logstash, and Kibana, along with Filebeat as a service. Finally, this chapter introduced X-Pack, which will be covered later in this book.

In the next chapter, we will learn about Elasticsearch in detail, APIs, QueryDSL, and so on.
