Design And Implementation Of Private Cloud Service Platform Based On OpenStack

With the continuous development of cloud computing,cloud computing market is rapidly expanding.At present,cloud computing is divided into public cloud and private cloud.Compared with public cloud,private cloud has many features like business customizable and data security.Therefore,more and more enterprises or government choose to deploy private cloud,and the private cloud market is also growing rapidly.Development of private cloud service platform to provide users with a complete cloud service solutions,including computing,storage,networking and other functions.Users can deploy services on the created VMs and ensure the stable operation of the service through functions such as flexible scaling and fault migration.By studying the cloud service provider's product and use framework at home and abroad,it proposes to develop Open Stack-based cloud service platform.Combined with the functions of cloud service platform from other vendors,we analyze the demand of the system,clarifies the interaction between cloud service platform and other systems.Then it is divided into seven major functional modules such as process order management,virtual machine,image management,private network,block storage,virtual firewall,flexible scaling,failover and data synchronization.Based on the functional requirements analysis of each module,we detail the design of each module,using flowcharts,timing diagrams to illustrate its business logic,and detailing the entire business process.And then according to the detailed design of each module,we designs database table,analysis of the relationship between the various tables and table structure.System uses the MVC framework,using C# 6.0 as a development language.The database using SQL Server 2010 for development and implementation.Finally,the interface diagram of each function module is given,and all the functions are tested at the same time.We analyze the test results,all the functional requirements of the system have been achieved,in line with the design requirements.The system is developed according to standard software development process.The system is running stable,low failure rate,and provide the cloud service platform that powerful and easy to operate.All customer give a consistent recognition and praise while using system.The system has a very good application prospects.
