Elastic Stack
Elastic Stack (formerly 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). Together, they enable centralized logging, monitoring, and business intelligence applications.
Developers should learn Elastic Stack for building scalable log management, monitoring, and data analytics solutions, especially in DevOps and cloud-native environments. It is ideal for use cases like application performance monitoring (APM), security information and event management (SIEM), and real-time business analytics, as it handles large volumes of structured and unstructured data efficiently.
