In the previous chapter, we saw how you can take an Elastic Stack application to production. Armed with all the knowledge of the Elastic Stack and the techniques for taking applications to production, we are ready to apply these concepts in a real-world application. In this chapter, we will build one such application using the Elastic Stack that can handle a large amount of data, applying the techniques that we have learned so far.

We will cover the following topics as we build a sensor-data analytics application:

• Introduction to the application
• Modeling data in Elasticsearch
• Setting up the metadata database
• Building the Logstash data pipeline
• Sending data to Logstash over HTTP
• Visualizing the data in Kibana

Let's go through the topics.
