Fundamental reform of Data center network

It is now a strong phase of technological and economic development, and data centres are at the heart of this phase. While cloud computing is driving technology and economics forward with technologies such as processors, storage, security, and software, this development has also strained the traditional data center network capabilities. As we know, cloud computing's resource-sharing mechanism increases flexibility as well as cost savings. In addition, cloud computing also supports the "Pay-as-you-go (Pay-as)" model. But the intranet of the data center still needs to connect all the servers, storage, devices and routers in the data center. So to fully implement cloud computing, the fundamental reform of the data center network is essential.

The current network is connected to a growing number of virtual devices and physical devices, so in order to manage these resources in a large scale, enterprises need to simplify the network, and this task is extremely difficult. We know that the complexity of management increases exponentially with the increase in equipment. In the past, customers had only two choices: either to deploy multiple small networks or to deploy large networks that contain large amounts of resources. The former is simple, but inefficient; while the latter improves efficiency, management is complex.

The Juniper Network, however, argues that companies do not need to make such a compromise choice. Because the traditional data Center architecture era is coming to an end. We see that in response to the advent of the internet era, data centers have changed in many ways, and the network is about to stride into the era of cloud computing. Now the IT department should take a decisive step to help the enterprise meet future development needs.

And what is the decisive step? The answer is cloud Ready data center network. The successful construction of an extensible cloud Ready Data Center network includes three key steps: simplification, sharing, and security.

The first is to simplify the physical network infrastructure. This requires a reduction in the number of network devices, network levels, and administrative tools. In the future, by using a single logical switch, an enterprise can expand securely and reliably across the data center and connect all servers, storage, and devices.

Secondly, after the network simplification, the dynamic sharing function is realized to realize the efficiency of the resource library. Only network virtualization can support large resource pools for high flexibility.

Finally, once a resource is shared, it is important to consider using the appropriate security model to ensure its security. At this point, we will no longer use traditional edge protection, but by improving the accuracy of the security model to achieve security sharing infrastructure.

By re-examining traditional methods and actively preparing for cloud computing, the data center networks that the IT department builds can deliver larger economies of scale, higher service levels, simpler management, and lower costs.

Therefore, the simplification, sharing and security of the network is the key to the successful construction of the cloud Ready data center.
