The overall architecture and business design of virtualized data center systems

The VDC system is divided into four layers: physical layer, virtual layer, management layer, business layer, mainly composed of five parts: virtual resource pool, virtual management platform, operation management system, portal and cloud terminal. Physical layer mainly includes the existing physical hardware equipment and subsequent expansion of physical hardware equipment. The virtual layer consists primarily of server virtualization and storage virtualization. Through the corresponding virtualization technology, a physical computing resource pool and a storage resource pool are formed, so that the upper management layer can dispatch and manage. Management includes a virtual computing management platform for server virtualization management, a virtual storage management platform for storage virtualization management, and a system operations management platform. The business tier consists primarily of portal platforms for different businesses and corresponding 3G terminals, thin clients, and other clients.

VDC Business

The VDC system is based on IaaS cloud computing technology to achieve the ability to lease business as the main goal, through rapid deployment, real-time response, on demand. VDC services and products should be provided at least to achieve the following four kinds: VPS Cloud host leasing business, flexible enterprise cloud rental services, online cloud storage services, cloud terminal combination services.

2. Flexible Enterprise Cloud Business

Business definition: The flexible computing business is a cloud computing service that calculates resources on demand. Flexible computing services provide a range of computing resources with different specifications. These specifications include: CPU performance, memory, operating system, disk, network. Different sizes of computing resources have different prices. Users can apply for computing resources of different specifications according to their needs. In view of the customer's abrupt, the temporary massive computation and the storage resource demand, provides the enterprise customer a virtual flexible computing cluster environment, realizes the user dynamic expansion or reduces the service configuration (CPU, memory, storage) as well as increases or deletes the elastic virtual host number. Multiple virtual hosts can make up the cluster working mode and can easily use unified storage space. Full adoption of dynamic allocation management is a project or event form to promote the whole system of a behavior. Efficient and rapid scheduling of resources, the system's computing resources to effectively integrate, so that it can deal with the flexibility of customer business needs.

Business Function Description: Flexible computing business to achieve the calculation, storage, network resources packaging sales, computing resources in accordance with the use of computing resources for the performance and use of time charges; for storage resources, according to storage capacity, storage time, storage iops and data volume, the network resources according to traffic, And the IP address of the resources of the lease time charges.

Compared with the traditional host rental business, the flexible computing business has the characteristics of rapid deployment and payment according to the usage. The entire business process does not require a service provider to manually participate in allocating resources, and can automatically redeploy resources based on service policies based on user business statistics and SLA requirements. Compared with the VPS host business, the flexible computing business has better reliability and finer billing granularity. As a cloud computing service, flexible computing services also provide a Web service interface that allows business systems to dynamically change resources to achieve automatic scaling. Flexible computing business compared with the virtual host business, provides a virtual exclusive host, and the virtual host provides a shared host, users of poor isolation, security is poor, generally only suitable as a specific application.

Service value: such as media, games and ISP service providers and other user groups for IDC Resources leased host number and load situation is difficult to predict, their needs generally have the following characteristics: User access to the periodic pulse type; Private data centers are formed between virtual hosts; Based on these features, these customers want to be able to quickly build secure, resilient private data centers with some technical means. Flexible enterprise cloud business is very suitable for such applications. Through flexible enterprise cloud business, can provide customers with centralized management, reliable performance, good business flexibility and flexible billing model, as well as the flexibility to build business-specific data centers, instant rental, on-demand expansion, on-demand payment mode.

3, online cloud storage business

Business definition: Online cloud storage through the cloud storage technology, consolidation and efficient scheduling of storage resources to meet the flexible use of customer needs. Cloud storage is more than just a piece of hardware, but a system consisting of network devices, storage devices, servers, applications, public access interfaces, access networks, and client programs. The online cloud storage business needs to satisfy the disaster-tolerant backup business demand of group enterprises; Support a variety of applications, such as cloud backup, cloud data sharing, cloud resource services, etc., but also provide a standardized interface for other network services to use, according to access to the nearest principle, the closer the geographical location, the more efficient data transmission between entities, the lower the cost. The current backup of business data in VDC provides a step-by-step service to back up the user's own data to the cloud. The online cloud storage business can combine centralized storage with distributed storage. can be realized according to the actual needs of customers to adjust the size of storage, and provide the corresponding disaster preparedness business.

Business function Description: To have established their own information system customers, especially some governments, large and medium-sized enterprise customers, more attention to system data security and reliability. However, the construction disaster preparedness system has large investment, long cycle, high maintenance cost and difficult management, so they need: any location, any time, use any network terminals for data storage, guarantee data security, reliability, transmission efficiency and other indicators; Support massive data management and provide public service support function Long-term data storage and avoid high initial cost inputs, and secure and reliable remote Storage backups at low cost.

Service value: Through the online cloud storage business, through a variety of network service support, customers can quickly and flexibly adjust the allocation of it storage resources, through a variety of technical means to ensure long-term data storage, safe and reliable, smooth migration.
