Data center & Cloud Computing

Construction of data center disaster recovery system based on cloud technology

The current data center is no longer an isolated computer room, but a building complex. A data center can contain many branch data centers, which can be said to be data center groups. These branch data centers are located in different locations, but can be interconnected through the network to complete the corresponding service deployment. Amazon, Facebook, Google, Ali, Tencent, Baidu and other large Internet companies, in order to enhance the customer access experience, will establish their own data center branches in different regions to meet customer access needs in different regions, the data center is no longer limited In one or several computer rooms. These data centers need to interact with each other and need to exchange information with each other. This requires interconnection to form a DCI network, a data center interconnect that includes both physical network level and logical network level technologies. In order to achieve data center interconnection in different regions, there are multiple transmission methods. FiberMall can provide bandwidth and multiple services for fiber transmission by using technologies such as CWDM / DWDM without adding fiber resources. At the same time, the fiber link protection solution is provided to solve the problem of jumping to the backup fiber route when the single fiber route is interrupted, thereby providing the security of the fiber transmission and reducing the possibility of data center shutdown.
