Zhangjiang data center is a new cloud data center, and the existing Jinqiao data center is transformed into a cloud to build a Shanghai city shuanghuo service architecture, and Shanghai and Foshan build a two place three center architecture

the overall technical architecture of Zhangjiang Kayuan cloud data center is planned to be four horizontal and two vertical. The four horizontal refers to: infrastructure service layer (IAAs), data service layer (the number of revolutions is also about 1400 revolutions per minute DAAS), platform service layer (PAAS), application software service layer (SaaS); The four verticals refer to: resource capacity support system, information security system, management system and standard system

construction content of shuanghuo cloud data center

the system construction of Tian'an property insurance shuanghuo cloud data center starts from the enterprise strategy and designs the enterprise level business architecture and it architecture according to the objectives determined by the business strategy and it strategy. It mainly includes the following key construction contents:

1 The construction of three centers in two places -- dual active in the same city and dual active deployment of remote disaster recovery

business. Through wavelength division optical fiber interconnection, when a data center level disaster or failure occurs in Zhangjiang card Park data center, the switching is approved through the disaster recovery process, and the business can be switched from Zhangjiang card Park data center to Jinqiao data center at the minute level

the role of Foshan disaster recovery center remains unchanged, and data level disaster recovery is still done. The data replication architecture of Jinqiao and Foshan remains unchanged. A new data replication/backup mechanism is built between Zhangjiang Kayuan data center and Foshan data center, forming a disaster recovery architecture of three centers in two places. When a regional disaster occurs in Shanghai business center, Foshan data center can provide complete data level disaster recovery support

use GSLB, Intelligent DNS, database data replication, storage gate, intelligent application management and other technologies to provide dual activation schemes for various business applications such as BS and CS, and realize dual activation at the front-end network, application and data levels

in order to ensure business continuity, provide the configuration and arrangement of dual active applications, and provide automatic deployment, monitoring and drilling of dual active applications. It also carries out topology management and application monitoring for the dual active application network, grasps the health status of the dual active application in real time, and supports the drill and switching of the dual active application with one click

2. The construction of Zhangjiang green data center

the construction of the data center must meet the current needs and applications, and also face the development needs of rapid growth in the future. Therefore, it is necessary to ensure that the new data center in Zhangjiang has the characteristics of high quality, high security, reliability, flexibility, openness and so on. At the same time, in the process of data center construction, Tian'an property insurance actively responded to the call of relevant national departments for data center to reduce energy consumption, fulfilled the social responsibility of enterprises, reduced the impact of carbon emissions on the environment, and committed to building this project into a green and efficient new data center

the newly-built data center in Zhangjiang Kayuan adopts the micro module solution with closed hot channel, and its refrigeration adopts the verified inter row air conditioning mode of chilled water, which can maximize the use of natural cold sources in combination with the climatic characteristics of the project site

modular IDC encloses it cabinet, air conditioning system, heat dissipation system, power distribution system, monitoring system, fire protection system, security system, lighting, etc. in a modular box; Through the isolation of cold and hot channels, effective air distribution is formed to meet the operation requirements of IT equipment

the cabinet, air conditioner, power distribution, gas extinguishing, alarm, security, wiring, etc. in the module are of integrated design, which adopts a fully enclosed structure and can reach the protection grade of IP66

3. The replacement demand of railway fasteners may promote the new growth of the company's deeds, and the safety construction of network

the construction of data center network follows the following principles:

the stability and reliability of data center products and networks is the first demand, and the redundant deployment of key equipment and lines

minimum transformation principle

minimize the changes to the existing network, protect the existing investment, and do not affect the application systems running in the existing data center

compatibility principle

the network protocol and business deployment should be as compatible with the existing network as possible

the data center network should maintain the ability of continuous evolution to the future, including the smooth upgrading of equipment and the ability of evolution to Sdn

the entire data center is partitioned according to functions, mainly divided into two categories: export network partition and business network partition. Firewalls are used for security isolation between partitions. In the Internet access area, firewalls are deployed in a heterogeneous manner. The service partition adopts a three-layer network architecture. The access control between the functional areas is carried out by the firewall and ACL, and the security protection is carried out by the firewall at the edge of the network. The firewalls in key business areas (such as the Internet access area/core area) are heterogeneous. DDoS and uplink are deployed in the Internet access area as management devices, and the DMZ deploys WAF for the security protection of the application layer

in order to ensure the dual active deployment of business between Zhangjiang Kayuan data center and the existing Jinqiao, vxlan, a large two-tier network technology between data centers, is used to open up the network resources of the dual active data center. Through the big two-tier network, clustering, resource sharing and fault detection across data centers can be realized

4. Application migration guarantee

in this project, a large number of businesses need to be transformed and migrated to Zhangjiang new cloud data center, and the coupling of businesses is strong, so perfect implementation steps and emergency mechanism are required in application migration

the project team has formulated systematic migration steps, including business information collection, evaluation and analysis, scheme design, migration verification, simulated migration, trial operation, acceptance test. And in the operation steps: each link should be documented for traceability

at the same time, the project team has developed reliable emergency response measures to reduce the risk of application migration. And built a perfect backtracking mechanism, once there is a problem in the business verification, it can immediately backtrack the business without affecting the business

5. Future technology capability output
