Question 1

What is Elastic Stack?

Accepted Answer

Elastic Stack is a set of open-source tools developed by Elastic that allows users to collect, store, analyze, and visualize large volumes of data in real-time. It is commonly used for search, logging, metrics analysis, and security analytics purposes. Elastic Stack consists of several components, including Elasticsearch, Logstash, Beats, and Kibana, each serving a specific function:

Elasticsearch: A distributed search and analytics engine that stores and indexes data in real-time, enabling powerful searching, aggregating, filtering, and analyzing capabilities.
Logstash: A data processing pipeline that ingests data from multiple sources, performs transformations, and sends it to various outputs, such as Elasticsearch for indexing and storage.
Beats: Lightweight data shippers that can send data from thousands of sources to Elasticsearch or Logstash. Beats include various modules tailored for specific use cases, like Filebeat for ingesting log files or Metricbeat for collecting and shipping system and application metrics.
Kibana: A data visualization and exploration platform that leverages the indexed data in Elasticsearch to create interactive dashboards, charts, and graphs. It allows users to analyze data, monitor system performance, and gain insights through visualizations.

By utilizing Elastic Stack, users can centralize their data, search and analyze it efficiently, detect anomalies, and gain valuable insights from their data in real-time.
