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 11: Observing Applications and Infrastructure Using the Elastic Stack

Over the course of this book, we've looked at how the Elastic Stack can easily and flexibly ingest various types of data sources for search, visualization, and analysis. Modern IT environments comprise multiple components, each powered by different underlying technologies. Running your IT business in production today is a high stakes job and Site Reliability Engineers (SREs) typically perform the important role of keeping your environment up and running. Consider some of the following observations in relation to modern IT environments and the implications these have for SREs:

  • Users and customers have incredibly high expectations around the reliability and availability of your services.

Online businesses, given their global reach, are generally expected to be always available. A company offering an availability Service Level Agreement (SLA) of 99.9% has an allowed downtime every year of...
