Elastic Stack
Elastic Stack is an open-source platform for data ingestion, search, analysis, and visualization, primarily used for log and metric data. It consists of Elasticsearch (a distributed search and analytics engine), Logstash (a data processing pipeline), Kibana (a visualization and management interface), and Beats (lightweight data shippers). The platform enables real-time data exploration, monitoring, and operational intelligence across various data sources.
Developers should learn Elastic Stack for centralized logging, application performance monitoring, and security analytics in distributed systems, such as microservices or cloud-native applications. It's particularly valuable for DevOps and SRE roles to troubleshoot issues, analyze trends, and create dashboards for operational insights, with use cases including log aggregation, business analytics, and threat detection.
