| Summary: | 碩士 === 大同大學 === 資訊經營學系(所) === 101 === As the advance of information technology, many information systems which are widely used in enterprises offer kinds of services. Also, those produce many log and integrated storage. When the abnormal data appears, system can immediately collect and analyze log. Traditionally, the process of analysis will produce lots of log. It needs to spend a lot of time doing analysis and cause too many record to be generated. Therefore, how to keep expanding storage capacity becomes the important issue. In order to solve the efficiency of analysis the limit of storage, my research use distributed cloud computing architecture. That can improve the analysis of audit trail. Also, storage doesn’t need to concentrate in one server. It decline limit of storage capacity.
The purpose of my research use distributed cloud computing architecture to audit log and the way to do distributed storage. The achievement is to solve above objectives. My research use Hadoop that is wildly used platform. Using Hadoop center technology, MapReduce, HDFS and Hive system, use those to manage log and to solve the problem of storage capacity. Through the analysis, find abnormal data and repair it immediately. Therefore, it would reduce execute time and the limit of storage capacity.
