Private disaster recovery cloud case of a certain network operation group
The network operation group and its subsidiaries majors in the businesses: internet access service, network engineering design construction, network value-added service, network device research & production and etc.
As a network operation enterprise, the group has multiple information systems to meet different business app demands. The internal information system provides information support for the normal operation and high-speed development. But while the information system is running, information systems and their data will confront great threat from disasters like illegal operation, HW fault, SW error, human factors, natural disaster and etc. once information system data is lost or business is down, irrecoverable property loss will be caused.
The group information center fully considers the necessity of data disaster recovery for information systems and claims the disaster recovery demand for its internal information system. The cluster headquarter is in Chengdu, and information center plans to build a disaster recovery center in Chengdu to realize the city-wide disaster recovery protection for the business system of Chengdu production center. Meanwhile, it should provide remote disaster recovery for the business system of subsidiaries in other cities.
After investigating the user demand, Rose combines the IT system architecture and builds a city-wide disaster recovery center in Chengdu. The solution topology is as below:
The city-wide server room in Chengdu plans and implements a disaster recovery center where virtual platform is deployed. In this solution, virtual servers work as disaster recovery center and provide 1-1 disaster recovery protection for the key business server in production center. Besides, local protection solution will be built in current city first for the key business system in other cities. On the basis of local protection, the key business system data of remote cities will be replicated to Chengdu disaster recovery center.
It is to build independent private disaster recovery cloud for user to realize local standby and remote disaster recovery effect. The scale of disaster recovery center can be expanded dynamically and new nodes could be added according to actual user disaster recovery demand.
It supports byte-level data replication in real time and only transmits changed data. This ensures the consistency and availability of disaster recovery data. It supports different app and database, and the simple deploymentcould easily realize data disaster recovery.
It cooperates with app system in depth and monitors app resources in real time. If any disaster or accident occurs on production server, the disaster recovery server will instantly take over related app service.
It supports transmitting compressed data. Network traffic control can be user-defined, so as to adapt to WAN/private network.
It supports transmitting encrypted data to avoid and data disclosure during transmitting process.
Disaster recovery center is built on virtual platform. This simplifies the deployment mode of disaster recovery center, integrates and optimizes SW/HW resources.
