The Partition of Security Domain and Protection Development Trend of Data Center

As an information resource center of Internet, data center requires the high security, high reliability and high bandwidth. With the optical fiber transmission technology emerging, high bandwidth is no longer a problem, to achieve high safety and high reliability, the previous approach is the deployment of various safety protection equipment at the boundary after the partition of security domain of data center, then the network structure becomes more and more complex, the maintenance is more and more difficult, the utilization rate of the equipment becomes low. The cloud computing concept provides a reference for the development of the network, then the network based on software and hardware tightly coupled, and network and security are tightly coupled, so that the whole data center network becomes a cyber source pool, without extra equipment, which allowing manager to flexibly allocate different security resources according to the business security requirements and business expansions. The protection of safety domain changes from domain boundary to the internal.
