Private Cloud Management Platform And Its Key Technologies On Openstack

With the rapid development of information technology, traditional parallel computing and grid computing models and other computing modes has evolved into clouding computing. Cloud computing is not only a new IT service model but also a technology mechanism that can provide a powerful computing resources. In cloud computing, users can obtain the required resources (such as computing, networking, storage, applications, etc.) in an easily scalable way through the network according to their needs. In order to support multi-user demand cloud computing access to IT resources and ensure service reliability, cloud computing also formed a technology mechanism, and the cloud computing platform is a concrete manifestation of this mechanism. As a new computing model, cloud computing has been widespread concern in industry and academia, while low-cost and open nature of open source software is also promoting cloud computing services to reduce product costs, improve compatibility. The open source cloud computing architecture also has been continuously developed.This paper firstly introduces the basic concepts of cloud computing and related categories, then analyzes the development of cloud computing at home and abroad, leads the research background of this paper. For the popular open source cloud computing management platform, made a detailed presentation of the concept. Then, introduce the details of OpenStack that is the current widespread concern in open source cloud computing management platform from the logical architecture, conceptual architecture, and the physical architecture and the key technologies. In addition to doing a detail introduction to the high available solution of OpenStack, and analyzes the feasibility of the solutions. Based on these analyzes, deploy a private cloud computing management platform that is used internal based on OpenStack, and the users can get guests they needed from this platporm. Meanwhile, complete the high availability configuration of the key components of the OpenStack Nova-Network, message queues RabbitMQ and MySQL database, and finally complete the cloud platform functional testing and high usability testing.
