Abstract： With the development of information technology and Internet， search engine plays an important role of internet service infrastructure with the feature of large scale dimensions， which focus on two aspects of data storage and data processing. With the aim of new architecture of network operating system， this project breaks through key technologies in large-scale distributed data sharing and management， efficient resource scheduling， virtual resource management， large-scale distributed system maintenance， and proposes several technical achievements including high performance storage engine and system design， load balance strategy based on virtual partition in MapReduce environment， performance-driven data balancing method in heterogeneous Hadoop cluster environment， resource measurement method in cloud computing， distributed computing engine design， system design of data intensive computing， job finishing time schedule algorithm based on historical information ratio factor dynamic adjustment， idle node evaluation schedule algorithm， MapReduce job injection load balance strategy， application remote virtual operation and platform design， multi-level network design for large-scale data center， large-scale cluster system monitoring and management， large-scale cluster system software remote deployment， low-energy， high-density server cabinet design， and clustering management system. With the support of internet search service from Baidu Inc.， the project design and implement new generation of network operating system with independent intellectual property rights based on large-scale cloud computing data center， which aims to provide technical supports for search services and clustering platform in data center， large-scale data storage and processing capacity for search engine and operational supports for upper open application services.
