How Netflix Leverages Elasticsearch for Operational Intelligence

Elasticsearch is a popular open-source search and analytics engine that enables powerful log analytics and real-time data insights. Here's a quick overview of some of its key capabilities:

  • Document-oriented storage allowing flexible schemas for diverse data types
  • Distributed and scalable architecture for handling huge volumes of data
  • Fast and advanced full-text search along with aggregation analytics
  • REST APIs for easy integration and horizontal scalability
  • Pluggable integrations for ingesting data from disparate sources

With these features, Elasticsearch is commonly used for log analysis, operational monitoring, application performance management, and data visualization.
