Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Overview of Elasticsearch

The video tutorial provides an overview of the Elastic Stack, focusing on its components like Elasticsearch, Kibana, Logstash, Beats, and X-Pack. It explains how Elasticsearch has evolved from a scalable search framework to a versatile tool for handling structured data and performing complex aggregations. The tutorial also covers the use of Kibana for data visualization, Logstash and Beats for real-time data streaming, and X-Pack for advanced features like security and machine learning. The Elastic Stack is presented as a comprehensive framework for data publishing and visualization.
