Elastic Stack
Elastic Stack (formerly known as ELK Stack) is an open-source platform for searching, analyzing, and visualizing data in real-time, primarily used for log and event data analysis. It consists of Elasticsearch (a distributed search and analytics engine), Logstash (a data processing pipeline for ingesting and transforming data), and Kibana (a visualization and dashboarding tool). The platform enables centralized logging, monitoring, and security analytics across various systems and applications.
Developers should learn Elastic Stack when building applications that require centralized logging, real-time monitoring, or security information and event management (SIEM) capabilities, such as in microservices architectures, DevOps environments, or large-scale distributed systems. It is particularly valuable for troubleshooting issues, analyzing user behavior, and ensuring system reliability by aggregating and visualizing logs and metrics from multiple sources.
