How can datacenter migration improve data security?

Datacenter migration，Traditional data centers do not always meet the needs of large numbers of users to retrieve data in real time. The surge in demand for big data has put pressure on data centers, which requires data centers to increase data transmission speed to accommodate more Internet users. Therefore, data center is now transforming its main functions from the past storage to real-time data analysis according to demand.

This functional transfer makes the block chain more valuable and can verify data set changes across multiple data centers. However, this method also needs an infrastructure to meet the high bandwidth, secure and fast data transmission system for data, video and audio transmission. Now, many data centers are transforming their traditional network architecture into a framework that can meet the needs of the block chain system for processing data.
Changes in infrastructure
The traffic of the traditional data center is mainly between the client and the server, but the server to server traffic is dominant in the Internet data center that supports the cloud computing application. Internet data centers must also provide continuous experience for users with diverse needs. Therefore, the network architecture of these data centers needs to deal with the peak traffic normalization more efficiently.
At present, the architecture used by most data centers is a tree network composed of three levels, including core layer, aggregation layer and access layer. This model can be effective when the transmission is mainly between the client and the server. However, this model is less for applications requiring high bandwidth and delay problems. Large data centers are now migrating to the leaf ridge network architecture, because it is more effective in transmitting data between servers.
However, due to the need of vane switches to connect each backbone switch, the wiring of this architecture is much more complicated. The main distribution area (MDA) of the data center using leaf ridge network structure has higher server density, which requires greater cooling capacity. The MTP to the LC module is good for this architecture, because it can implement the full mesh of the leaf switch, instead of dividing the 40G port of the backbone switch into four 10G channels.
Once the infrastructure can support the required traffic, the data center will be able to protect its data more effectively. Block chaining is becoming a popular solution to data security. Because the encryption method used by block chains can distribute data between multiple servers. This method makes the block chain difficult to invade, because each block usually contains only the encrypted hash function of the previous block. Block chaining is initially used to protect encrypted currencies such as bitcoins, but they are also used to provide data security outside the financial sector. Data centers that store sensitive data are the first data centers that use block chaining as a secure storage method.
Future demand
Because of the increasing popularity of 5G networks and IoT, data center infrastructure will need to support more interconnected devices. In the transformation process, data centers also need to meet the demand for increased traffic and secure storage. By using servers that can withstand higher density, the leaf ridge network architecture will provide an economical solution for distributed data management. The architecture can upgrade the bandwidth of large data centers from 10G to 40G, and help to transition to 100G network in the future. Therefore, data center will adopt block chain technology to improve the security of data storage.
