Overview of this book

The Elastic Stack helps you work with massive volumes of data to power use cases in the search, observability, and security solution areas. This three-part book starts with an introduction to the Elastic Stack with high-level commentary on the solutions the stack can be leveraged for. The second section focuses on each core component, giving you a detailed understanding of the component and the role it plays. You’ll start by working with Elasticsearch to ingest, search, analyze, and store data for your use cases. Next, you’ll look at Logstash, Beats, and Elastic Agent as components that can collect, transform, and load data. Later chapters help you use Kibana as an interface to consume Elastic solutions and interact with data on Elasticsearch. The last section explores the three main use cases offered on top of the Elastic Stack. You’ll start with a full-text search and look at real-world outcomes powered by search capabilities. Furthermore, you’ll learn how the stack can be used to monitor and observe large and complex IT environments. Finally, you’ll understand how to detect, prevent, and respond to security threats across your environment. The book ends by highlighting architecture best practices for successful Elastic Stack deployments. By the end of this book, you’ll be able to implement the Elastic Stack and derive value from it.

Chapter 1: Introduction to the Elastic Stack

Welcome to Getting Started with Elastic Stack 8.0. The Elastic Stack has exploded in popularity over the last couple of years, becoming the de facto standard for centralized logging and "big data"-related use cases. The stack is leveraged by organizations, both big and small, across the world to solve a range of data-related problems. Hunting for adversaries in your network, looking for fraudulent transactions, real-time monitoring and alerting in systems, and searching for relevant products in catalogs are some of the real-world applications of the Elastic Stack.

The Elastic Stack is a bundle of multiple core products that integrate with each other. We will look at each product briefly in this chapter, and then dive into each one in later chapters in this book. The Elastic Stack attracts a great deal of interest from developers and architects that are working for organizations of all sizes. This book aims to serve as the go-to guide for those looking to get started with the best practices when it comes to building real-world search, security, and observability platforms using this technology.

In this chapter, you will learn a little bit about each component that makes up the Elastic Stack, and how they can be leveraged for your use cases. Those of you who are beginners or intermediary learners of this subject will benefit from this content to gain useful context for Chapter 3, Indexing and Searching for Data, to Chapter 13, Architecting Workloads on the Elastic Stack, of this book.

Specifically, we will cover the following topics:

  • An overview of the Elastic Stack
  • An introduction to Elasticsearch
  • Visualizing and interacting with data on Kibana
  • Ingesting various data sources using Logstash and Beats
  • End-to-end solutions on the Elastic Stack
