클라우드 컴퓨팅 환경에서의 오픈소스 기반 로깅 시스템

Abstract

Cloud computing that provide a elastic computing service is more complex compared to the existing computing systems. Accordingly, it has become increasingly important to maintain the stability and reliability of the computing system, and troubleshooting and real-time monitoring to address these challenges must be performed essentially. At this time, the handling of the log data is needed, but this work may be more difficult compared to the traditional logging system. Because log data in cloud computing environment has a lot of challenges such as atypical format, multi-layer and multi-point, volatility. In addition, there are another challenges in order to have the admissibility of the collected log data in court. In this thesis, we design the logging service that provides the management and reliability of log data in a cloud computing environment. We implement the proposed cloud log system by using open sources on OpenStack platform, and then analyze the proposed system. The proposed system will present a new direction for the new logging system to the cloud service provider, and provide the service users with a new experience and a wide insight about the current situation.
