In Chapter 1, Machine Learning for IT, we learned what anomaly detection for IT is by looking at the fundamental steps behind the theory. Most importantly, we learned that, thanks to the Elastic Stack, Elastic machine learning (ML) allows us to operationalize anomaly detection, from analysis to visualization. Now, in this chapter, we'll roll up our sleeves and get to work installing the entire Elastic Stack. By doing so, we'll have a better understanding of the anatomy of Elastic ML. In this chapter, we will be covering the following topics:

• Installing Elasticsearch 
• Installing Kibana 
• Enabling ML features
• Elastic ML features
