이벤트 기반 서비스 기술은 실시간으로 발생하는 이벤트를 감지하고 분석하여 이에 대한 반응으로 서비스가 연동되는 기술로, 실시간 기업 환경 구축이나 유비쿼터스 서비스 환경 구축을 위한 핵심 기반 기술이다. 실시간 기업 환경에서 요구되고 있는 기업내 업무 프로세스에서 발생하는 다양한 정보를 실시간 모니터링, 분석하여 변화에 대한 신속한 대응을 제공하거나, 유비쿼터스 서비스 환경에서 상황에 맞게 적시에 맞춤형 서비스를 제공하기 위해서는 이벤트 기반의 서비스 기술이 요구된다. 본 고에서는 이벤트 기반 아키텍처의 개념, 발전 방향 및 구성 요소에 대해 설명하고, 실시간으로 발생하는 대량의 이벤트를 처리하여 의미있는 상황 정보를 제공하거나 서비스를 연동하는 기술인 이벤트 스트림 처리 기술에 대해 살펴본다.
