How to settle the electronic commerce architecture in cloud computing

E-commerce has penetrated into all walks of life, its fast, low-cost is attracting more and more enterprises to join. E-commerce platform is increasingly perfect, and to cloud computing, public computing model development. This paper constructs the initial cloud computing infrastructure by combining with the project of provincial Science and technology innovation and achievement transformation (home online e-commerce website) of Jiangsu Province, and probes into the key components of E-commerce on cloud platform and the relationship between them. Cloud computing technology makes future e-business more flexible and easy to use and saves energy, advances the application of public computing and green Computing in the field of E-commerce, and reduces the cost of online transactions.

1, the construction of electronic commerce cloud computing infrastructure

Cloud computing, as a future network application architecture, is emerging. Cloud computing is a way to share IT infrastructure, and it can connect huge system pools and provide services. Cloud computing enables enterprise data centers to operate more like the Internet, allowing computing resources to be accessed and shared as virtual resources through secure and scalable methods.

Virtualization is an abstraction layer, it separates the physical hardware from the operating system, allowing for more granular cutting and consolidation of the operational and storage capabilities of existing servers, providing higher it resource utilization and flexibility, and providing common interface standards for large-scale cloud computing integration, So that the calculation is common.

2. Key components and components of e-commerce on cloud Platform

In E-commerce system design, the Linux server built on virtual hardware resources is the basic system unit, using LVS (Linux Vir tual Server) and NAT (receptacle address translation) Technology builds a practical cloud-computing cluster system that enables flexible management and provisioning of application services across a wider range of data centers through intelligent content routing technology, enabling high availability, high security, high performance, low cost, and highly scalable features to be included in the cloud infrastructure.

In practice, the virtualization and LVS integration processes in cloud computing infrastructure construction are deeply explored. The virtual computing technology is very good at cutting the hardware calculation and storage capability and providing the standard interface for the smaller operation unit. LVS is a cluster construction technology based on load balancing technology under Linux. By cutting and reconstructing, the load balance of LVS dispatching is realized on the basis of this, which makes the distribution of computing power in cloud more reasonable.

In the cloud computing cluster, we further take "home online" e-commerce website platform as an example, pack and integrate all kinds of e-business business, process, application for cloud service, take SOA as core, and complete business layer service integration through Enterprise Service bus ESB. SOA is a specification for designing, developing, applying, and managing decentralized logical (Service) units in a computational environment. By analyzing the mutual invocation between services, SOA makes it easy for company managers to get data about when, why, and which business logic is being executed, which helps business managers or application architects iteratively optimize their enterprise business processes and application systems.

In the detailed design process of e-commerce system Web service, the heterogeneous loose coupling is realized by packaging and distributing the e-business process integration under Windows and Linux platform into service. So that the cloud business logic can be unified scheduling, build more flexible.

In order to solve the problem of the mobility of the WAN in the cloud, reduce the duplication of the network transmission and improve the bandwidth utilization. Content routing technology, intelligent DNS resolution technology, and remote incremental replication technology are used in storage management. Combined use of these technologies will greatly enhance the flow of cloud data. Enables dynamically configured operating systems, applications, or services to be uploaded to any corner of the cloud. In a perfect universal environment, the use of arbitrary devices and arbitrary networks, at any time can be a considerable quality of computing services. The focus of pervasive computing is to provide a customer-facing, ubiquitous adaptive computing environment. In the fusion space of pervasive computing, people can obtain digital services "anytime, anywhere" and "transparently", including E-commerce services. After the pervasive computing environment matures, users can naturally obtain the required network and computing services in any location in their lives and workplaces. As the user obtains computing services, the user does not need to consciously choose to use a device or network because the device that provides computing and communication has been integrated into the environment. Because of the ubiquitous computing power, information space will be integrated with the physical space of people's life and work. Ubiquitous information home appliances, sensor networks, embedded system equipment will be the carrier of future E-commerce. The growth of "home online" technology should conform to this change and better integrate into the next generation e-business system.
