A large well-known insurance company, which owns property insurance, life insurance, asset management and pension insurance, and other professional subsidiaries, and has established a nationwide marketing network and diversified service platform. It has thousands of branches, tens of thousands of employees and hundreds of thousands of property and life insurance salesmen throughout the nation, providing a full range of risk security solutions, investment banking and asset management services for clients nationwide.
With the gradual expansion of business scale, the requirements for IT system becomes higher gradually. Higher requirements for the reliability, scalability and agility of application system emerge after the large concentration of IT application system.
In order to meet the application requirements, Rich Cloud Technology establishes a new data center, in which the routing and switching products from a well-known manufacturer are used, fully ensuring the reliability and stability of the system. The network system is divided into several functional areas, including production network, office network, development and testing network, WAN access area, operation management area.
Effective dispersion of operational maintenance risk as well as the security attack risk at network security level can be achieved through partition and isolation. With effective partition and isolation, such effects can be limited within a smaller area, which can help to ensure the network security operation of overall application system. Furthermore, effective prevention against internal security attacks can be realized and scope of maintenance for maintenance personnel of different systems can be defined through partition so as to ensure the overall security of the application system.
With regard to the reliability of the system, it has completed construction of city disaster recovery center, with all secondary branches connected to two data centers, which eliminates single point failure of WAN, and provides strong support for the reliable operation of the entire application system.
In addition, faced with the increasingly complex applications, in order to improve the system reliability, scalability and manageability, as well as meet the rising demand of system throughput, it carries out the load balancing of server as the basic network architecture simultaneously while constructing the traditional network infrastructure.
Through load balancing system, the traditional network system closely fits the upper application system, so that the network can perceive the operation of the application. Whenever the fault is found, the user will be re-orientated to server which operates normally in a transparent way. Thus, the user can receive the best service. In addition, the load balancing system possesses powerful extended function. The security protection, safe access strategy, access acceleration and other functions can be extended through upgrading license, so as to provide reliable security and optimize the speed for the operation of applications.
