Design And Implementation Of Multi-tenant Information Management System Based On Eucalyptus

Cloud computing is a far-reaching IT technology that has emerged in recent years.It is a product of the integration of distributed computing,parallel computing,utility computing,network storage,virtualization and other technologies,which has been widely studied and applied.Cloud computing is a relatively new concept that brings together all the disciplines,technologies(Web services,virtualization)and business models used to deliver IT capabilities(software,platforms,hardware)as a service request,scalable and elastic.This is the new trend of computing where IT resources are dynamically scalable,virtualized and exposed as a service on the InternetNowadays,cloud computing is used as a model for most science,business,and so on.Eucalyptus is an open source implementation of a cloud computing infrastructure with a specific architecture and has become a trend in commercial applications.Today,many problems in the process of information construction of SMEs,for instance,first,no capital investment and maintenance costs;second,no professional IT personnel;third,no security monitoring service;fourth,serious waste of resources.By using Eucalyptus,you can process and store large amounts of data and perform parallel jobs(for example,analyzing system logs,customer data and customer relationship behaviors)to achieve SME informationization.Cloud computing has fundamentally changed the IT consumption model from a traditional product purchase licensing model to a service model.Computing resources,whether hardware,soft,ware,computing,storage,or network,provide services to consumers through the network infrastructure.This thesis is based on the cloud environment,which is constructed by Eucalyptus,and design an information management system for the chain industry.By implementing Internet technology,informationization and intelligence can be achieved in the beauty chain store.To begin with,this thesis illustrates brief introductions of the cloud platform Eucalyptus,which include cloud platform,hierarchical architecture and key technologies of multi-tenant.The next step is analyzing the requirement of the information management system,which can be divided into several models.Via researching on different subjects,customers,employees,products and the relationships between them respectively,the requirement analysis could be obtained.The last stage is to evacuate the functions and performances of the entire system by modeling.
