摘要
近几十年,随着互联网的发展,数据正在呈爆炸式增长。为了保存和处理这些数据,传统的IT架构已经满足不了,云计算应运而生。Hadoop是云计算下的一种分布式处理的软件架构,能够对大数据进行存储和处理,而它最核心的两大组件就是HDFS和Map Reduce,分别实现了分布式文件存储和分布式并行任务处理。文中,将基于PEPA对HDFS进行建模分析,并对HDFS的性能进行评估。
In recent decades,data has been in explosive growth with the development of the Internet.As the traditional IT architecture cannot meet the requirements of storing and processing the data,cloud computing has emerged.Hadoop is a distributed processing software architecture using cloud computing,which can store and process big data.The two main core components of Hadoop is the Hadoop Distributed File System(HDFS)and MapReduce,which implement distributed file storage and distributed parallel task processing respectively.In this paper,modeling analysis for the HDFS is conducted based on the Performance Evaluation Process Algebra(PEPA),so as to evaluate the performance of the HDFS.
