The Elastic Stack Study Notes
The Elastic Stack Study guide explains how Elasticsearch functions as the core storage and search engine, while Logstash and Beats handle data ingestion pipelines.

The Elastic Stack Study Notes and comprehensive Elastic Stack Study guide provide a structured deep dive into the ELK ecosystem Elasticsearch, Logstash, Kibana, and Beats , a powerful open-source platform built for large-scale data ingestion, storage, analysis, and visualization. These notes are especially valuable for data analysts, security engineers, and operations teams managing real-time logs and performance metrics.
The Elastic Stack Study guide explains how Elasticsearch functions as the core storage and search engine, while Logstash and Beats handle data ingestion pipelines. Kibana completes the stack with advanced visualization and investigative capabilities. Within the Elastic Stack Study Notes, security professionals learn how to centralize device logs and leverage KQL (Kibana Query Language) for structured threat investigations.
For data analysts, the Elastic Stack Study guide demonstrates how to ingest datasets using custom index templates and structured mappings.
It includes detailed installation walkthroughs across multiple operating systems (Linux, Windows) and containerized deployments (Docker), along with architectural breakdowns covering nodes, clusters, and scaling models. The guide also compares ingestion pathways Beats versus Logstash helping practitioners select the right approach for performance and scalability.
Advanced Kibana coverage within the Elastic Stack Study Notes includes dashboards, Canvas visual storytelling, geographic maps, and alert configuration. Practical cybersecurity case studies illustrate detection scenarios such as brute-force authentication attempts and phishing investigations using KQL queries and visual correlation techniques.

What about the notes updates?
if you have been following my YouTube Channel, you definitely know that those who subscribe to the second tier of my channel membership they instantly get access to a vast catalog of cybersecurity, penetration testing, digital marketing, system administration and data analytics notes catalog for 10$ along with the ability to receive all notes updates as long as they are subscribed so what does that mean?
This means if you want to stay up to date with the changes and updates to the notes and get access to other categories, I encourage to join the channel membership second tier instead. However, if you are fine with downloading the current version of this section of the notes then you can buy this booklet instead for a one-time payment.
Will the prices of this booklet change in the future?
Once another version of this E-book is released, which it will, the price will slightly change as the booklet will include more contents, notes and illustrations.
