Implementation of cloud computing management in the information construction of Audit Commission disaster preparedness

In the "Twelve-Five" plan, the information of disaster preparedness has been written into the key direction of the future government informatization. The establishment of disaster preparedness for government offices is being developed to target the three centres.

The three centres in the two places set up two data centers in each other, backup each other, establish a 3rd data center in different places, and backup each other with the other two centers. How to find the economical and effective scheme to verify the integrity and reliability of the backup data of the business and application system has been the key to the construction of Disaster preparedness Center and remote data backup in different places.

Recently, in full consideration of the National Audit Commission disaster Preparedness Center business system data calibration needs and combined with its own product characteristics, Pu-hua basic software for the Audit Commission disaster preparedness Center deployed with independent intellectual property rights of the I-virtualcloud cloud computing management platform.

The Cloud management platform includes a Management server and multiple compute node servers. From the hardware, only a few high-performance X86 architecture of the physical server, install the I-virtualcloud Server software separately, build the hardware hypervisor layer. In addition, simply install the I-virtualcloud Manager management software on a PC, and you can manage the computing server in a unified system. This enables the creation of virtual machine templates based on the business usage of the country's various points of application and the creation of virtual machines through templates that allocate computing and storage resources to virtual machines based on actual business requirements.

Because of the National Audit Office Changsha off-site disaster Preparedness Center is through the storage array remote replication function and the rest of the country data backup, but only to achieve data level disaster, the data integrity, usability verification can only do storage device level verification, can not achieve application-level data validation. To do application-level data validation, on the need to the national 19 points of application and database server in the Changsha Disaster preparedness Center to build a deployment, each point has 10 or so servers, if all the use of physical servers, on the need to purchase the deployment of nearly 200 physical server equipment, it will be a large amount of expenditure. Furthermore, these servers are used only to verify the security integrity of the backup data, not to host the business system, or even to always boot, which is obviously a huge waste of computing resources.

By deploying the I-virtualcloud cloud computing management platform, we created nearly 200 virtual machines for the National Audit Office's Changsha disaster Preparedness Center. Because the virtual machine is only used when the business data is validated, the business data of each point can be verified by batches. So users do not have to worry about 6 hosts can not host 200 virtual machines running concurrently, if the verification of 6 points of business data, you can only open the 6 points corresponding to 60 of the virtual machine, so that there will not be too heavy load, Calculate the lack of resources, so as to maximize resource savings, reduce it application costs.

The National Audit Office after the implementation of disaster preparedness information cloud management platform, has produced remarkable results, mainly reflected in 5 aspects:

One is to upgrade the disaster Preparedness Center disaster recovery level, from data-level disaster recovery to business-level disaster recovery. The second is to reduce the cost and improve the utilization of resources. The server virtualization technology can significantly reduce hardware procurement, transportation and peacekeeping management costs. Third, to facilitate the disaster preparedness Center for the establishment of B upgrade, expansion. Through the virtual machine dynamic migration technology, it can upgrade and enlarge the equipment without interruption of the business. Four is to facilitate the other points of data center to the cloud computing architecture upgrade. When the conditions are ripe, the other data centers can be easily upgraded. The service function of disaster preparedness Center is increased conveniently. Through the virtual desktop, virtual applications Publishing, delivery desktop and applications, so that users can always safely access the internal business.
