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.

Managing Elastic Agent at scale with Fleet

Fleet is a component that's used to manage Elastic Agent configurations across your environment. Fleet is made up of two components:

  • Fleet UI is a Kibana application with a user interface for users to onboard and configure agents, manage the onboarded data, and administer agents across your environment.
  • Fleet Server is a backend component that Elastic Agents from across your environment can connect to, to retrieve agent policies, updates, and management commands.

Fleet Server is a special mode of Elastic Agent and can be deployed centrally alongside your Elastic Stack deployment. You can configure multiple instances of Fleet Server in a load-balanced setup to scale performance and add availability. Fleet Server requires connectivity to the backing Elasticsearch cluster to operate.

The architecture with Elastic Agent and Fleet involved looks as follows:
