Elasticsearch는 강력하고 다재다능한 검색 기능으로 널리 사용됩니다.

아래 다이어그램은 상위 6개 사용 사례를 보여줍니다.

🔹 전체 텍스트 검색 Elasticsearch는 강력하고 확장 가능하며 빠른 검색 기능으로 인해 전체 텍스트 검색 시나리오에서 탁월합니다. 이를 통해 사용자는 거의 실시간 응답으로 복잡한 쿼리를 수행할 수 있습니다.

🔹 실시간 분석 실시간으로 분석을 수행할 수 있는 Elasticsearch의 기능은 사용자 활동, 트랜잭션 또는 센서 출력과 같은 라이브 데이터를 추적하는 대시보드에 적합합니다.

🔹 기계 학습 X-Pack에 머신 러닝 기능이 추가됨에 따라 Elasticsearch는 데이터의 이상, 패턴 및 추세를 자동으로 감지할 수 있습니다.

🔹 Geo-Data 응용 프로그램 Elasticsearch는 지리 공간 인덱싱 및 검색 기능을 통해 지리 데이터를 지원합니다. 이는 매핑 및 위치 기반 서비스와 같은 지리적 정보를 관리하고 시각화해야 하는 응용 프로그램에 유용합니다.

🔹 로그 및 이벤트 데이터 분석 조직은 Elasticsearch를 사용하여 다양한 소스의 로그 및 이벤트 데이터를 집계, 모니터링 및 분석합니다. ELK 스택(Elasticsearch, Logstash, Kibana)의 핵심 구성 요소로, 시스템 및 애플리케이션 로그를 관리하여 문제를 식별하고 시스템 상태를 모니터링하는 데 널리 사용됩니다.

🔹 SIEM(보안 정보 및 이벤트 관리) Elasticsearch는 SIEM을 위한 도구로 사용할 수 있으며, 조직이 보안 이벤트를 실시간으로 분석할 수 있도록 지원합니다.
