Design And Implementation Of Distributed Internet Information System For Large Internet Companies

Large Internet Co (such as Taobao) with the user visits, trade flow characteristics, the business system, transaction system requiring high processing capability, Single system architecture is difficult to support live now rapid development of business system, distributed system architecture has become the mainstream architecture nowadays Internet Co business system, between each subsystem by message communication, but with a variety of online promotions, appear seckill activities, A large number of users to access over the main message service system has become the performance bottleneck of traditional, Along with the development of new business on the Internet, different requirements for the message data of different business, need a message service system is the traditional single model can no longer meet the needs of business, So can support different mode, safe and reliable, strong processing ability, has the advantages of easy expansion of distributed information system of birth. Distributed information system can timely shunt flow, support real-time performance to meet different business expansion, the message processing, make the distributed information system become the most important part of the Internet company.In this thesis, a large Internet Co (Taobao) of distributed information system (notify) project, from the angle of large Internet Co, to distributed information system requirements analysis, design, implementation and maintenance of test as the main line, discusses distributed information system architecture design, protocol design, network topology, store design and operation the difference before and after the implementation of test methods, through the instantiation of the validation project. The main work of:1. the design and implementation of the framework of distributed information system design, protocol design, store design and network topology;2. Implementation of distributed message server code, do protocol pluggable, storage pluggable; 3. Implementation of distributed interactive protocol, so that the individual information service system platform for the implementation of management under the same protocol;4. The realization of a messaging client, make the client through the distributed unified platform, transparency news service, do not need to specify a fixed message service address, a distributed platform automatically push. Do news services distributed;5. Automatic management implementation of cluster service using Paxos algorithm. Automatically according to the network is a combination of manual and automatic distribution of machine resources, providing high availability, safe and reliable service;...
