Virtual Private cloud information Island Moat Alternative

Absrtact: As the basic platform of "cloud computing", data center is the guarantee of "cloud computing", and it is also the key to ensure information security and realize autonomous control.

In a comprehensive way, the "cloud computing" has the extremely strong computational ability and the low cost, the high security and so on the characteristic, has the very important value and the significance in the electronic government affairs information resources sharing domain. "Cloud computing" is considered the core of the next round of the information technology revolution, and the next 3-5 years will be the focus of global wrangling. The core idea of cloud computing is to manage and dispatch a large number of computing resources with network connection, and form a computing resource pool to serve the users on demand. A network that provides resources is called a "cloud."

Suzhou Industrial Park E-Government data center was founded in 2005, as the management of data center, the Park Computer Information Center actively follow the forefront of industry development, using "cloud computing" to promote the regional e-government construction of the file upgrade, the construction of an efficient and safe "e-government private cloud."

"System Island" hinders the development of government affairs informatization

The administrative information system of the park adopts the centralized management mode, since 2003, with the advancement of government Affairs informatization, the information system running in the district government data center reaches up to more than 100, the government Affairs data center hardware equipment is multifarious, hosting all kinds of servers more than 90 units, storage equipment 5 sets; The network structure is complex, export 4, Lane 8.

At the same time, with the continuous development and application of information technology, the traditional island chimney-type system is faced with extremely high operating cost and difficult maintenance and management work. Whenever hardware and software are upgraded, large data migrations and long downtime must be handled.

More importantly, in order to achieve the availability and reliability of each application system, it is necessary to spend high hardware and software equipment input to achieve system redundancy, because the system is isolated, the redundancy mechanism between each other can not be shared, and the utilization of each system is very low, resulting in a very high cost of integrated system.

"Virtualization" Building new data centers

In the face of the problems of dispersed resources, low utilization rate, complicated hardware and so on, optimizing system structure, improving resource utilization, simplifying operation and maintenance flow, finding a new resource management method is the problem that the computer Information center of the park has to consider.

Since 2006, the center has introduced virtualization technology, from server to storage to network, the virtual integration of various hardware resources has brought unexpected results, computer Information Center senior System Architect Di said: "After 5 years of step-by-step resource integration, At present, the government data Center has formed a 240-core CPU Total 536GMHz computing capacity, 960GB memory capacity and 30TB storage capacity of the virtual resource pool (the number of physical servers is only 12), and the government data center management staff only 2 people. Again this pool of resources to run, including the park-oriented Enterprise Services, public services, investment, finance, planning and construction, land, environmental protection, personnel, state-owned and so on more than 60 dedicated business systems, as well as the Administrative Committee of the day-to-day Office of the administration of electronic text system and mail system. The overall virtualization rate reached 90%, resource utilization reached 85%, and system availability reached 99.99%. ”

Through the application of virtualization technology, the park Computing Information Center has successfully managed to simplify the resource management, and explored the new mode of managing data centers.

The government data center under the "Cloud Computing" architecture

With the development of Twelve-Five informatization planning, it is a new target for the construction of e-government in the park to construct the application of corporate library for enterprise service, the application of the public-oriented population library and the geographic information platform for the application of government affairs. The private cloud of government affairs is the cornerstone of supporting the above three applications.

Virtualization is the prerequisite of cloud computing, the park Computer Information Center in the application of virtualization has accumulated a wealth of practical experience, so for the "cloud", there are more unique insights.

Di said: "In Physics, park government private cloud is no longer confined to a data center, will make full use of the park's existing multiple data centers, through high-speed network to connect it to form a Super Virtual data center, government-owned private cloud architecture in this super virtual data center, resources can drift in the data center like clouds. "In this mode, provides two levels of redundancy within the resource pool and resource pool, whether hardware replacement or maintenance maintenance, will not affect the normal operation of the system, so that the system services to achieve forever online."

For example, the corporate library application of the park, its application servers will be distributed across a pool of resources, which will "float" to a strong resource pool during daytime business hours, and at night, it will be moved into a resource pool with other applications, while other resource pools can go on standby to conserve energy. In a more figurative way, the "cloud" of these fluttering resources will provide resource services on demand for every business application, and these "clouds" can provide rainwater if the business unit needs "timely rain". The data center under the cloud computing architecture changes the way information systems must be implemented by adding hardware and complex system configurations, it transforms the hardware resources of the datacenter into services, and the computing, storage, networking, and operating systems, databases, communications services, and software interfaces become standardized resource lists, As long as the user units need to, through the "cloud" portal, you can let resources services "to come."

The resources in the cloud can be extended indefinitely by the user, and can be obtained at any time, on demand, and at any time.
