Financial Information Fusion and service Platform Based on Cloud Computing

Cloud computing is the important form of information service infrastructure and application model in the age of the Internet, is a new generation of information technology intensive development inevitable trend, its resource aggregation and virtualization, application services, and flexible specialization, on-demand supply and use of the service mode provide highly efficient, low cost, low power consumption of computing and data services, support all kinds of information, the application of special financial information. Cloud computing technology with its own technological advantage produces a great change for enterprise informatization construction, and the operation mode of the electronic commerce enterprise and other fields. With cloud computing platform as the core business service models, it will also have significant influence on society and Internet application mode on the existing business. The general theory and characteristics of cloud computing Cloud computing and financial information Cloud computing is a kind of new computing model based on the Internet, it can put the software and hardware resources, data and application as a service providing to users via the Internet. Cloud computing is a new method of infrastructure management; it can bring a lot of highly virtualized resources management, forming a huge resource pool, unified service. Cloud is actually a kind of metaphor for network and the Internet. The core idea of cloud computing is to get unified management and scheduling of a large number of network computing resources, constitute a computational resources pool to provide on-demand services to users. The resources in the “cloud” are unlimited extension in the user view, and can be obtained at any time, according to the need of users. Providing "computing" to customers (i.e. information processing service) is the core of the cloud computing model. Currently cloud computing services mainly include: infrastructure (IaaS), platform services (PaaS) and software services (SaaS), in addition to hardware service (HaaS), data (DaaS) and application service (AaaS) and etc. Financial cloud computing uses the constitutes principles of cloud model to make the financial institutions and the relevant institutions of data center connectivity, constitute a cloud network, or use cloud computing service providers of cloud network, spread financial products, information and services to the cloud network, in order to improve the ability to find and solve problems quickly for financial institutions, improve the overall working efficiency, improve processes, reduce operating costs, provide customers with more convenient financial services and financial information services. The server of cloud computing is in the following: 3rd International Conference on Materials Engineering, Manufacturing Technology and Control (ICMEMTC 2016) © 2016. The authors Published by Atlantis Press 1901 Chart 1: the service types of the cloud computing The characteristics of cloud computing 1) Large scale: huge "cloud" can give the user the unprecedented computing and storage capacity, for example the Google cloud has already more than 100 ten thousand servers. 2) Service virtualization: cloud computing supports users in any position, using a variety of terminal access application service. The requested resource from the cloud instead of fixed tangible entity. 3) Customization: cloud computing can construct the different applications according to the different needs of customers, the same cloud can support different applications running at the same time. 4) Extensibility: to meet the needs of the application and the user scale growth, cloud can be horizontal extension and vertical extension. 5) On-demand services: "cloud" is a huge resource pool; the cloud can be like water coal pricing. Users buy according to their own needs in order to get a specific service. 6) Users transparency: transparency makes it convenient to the users to a large extent. Transparent includes transparent operation and technology. 7) Low cost: the cloud server group automation centralized management makes a lot of enterprises no need to burden increasingly high cost of data center management and maintenance cost. And cloud commonality resource utilization than traditional system, so users can fully enjoy the low cost advantage of clouds and super computing power. In addition, the use of cloud also can reduce the user IT infrastructure investment and software development, update and maintenance expenses. Advantages of Cloud Computing Security Cloud computing provides the most reliable and secure data storage center; users don't have to worry about data loss, virus invasion and etc. When the user saves the document on the type of cloud service, it will minimize the possibility of loss or damage to the data. Because, at the other end of the "cloud", it has the world's most professional team to help customer information management, has the most advanced data centers to help you save the data, at the same time, strict authority management strategy can help customers to share data with a particular group. Function expansibility Cloud computing provides data for storage and management with almost an infinite number of possible, also for us to complete all kinds of application, provides almost infinite and powerful computing capacity. At the other end of the cloud, large cluster is composed of ten million servers SaaS(Software as a Service) PaaS(Platform as a Service) IaaS(Infrastructure as a Service) Such as Sales force /800APP ONLINE CRM Such as Goole APP Engine Microsoft Windows AZURE Such as Amazon EC2/ S3 Exclusive
