Data Center Security in the Software-Defined Age

According to IDC's forecast, the total amount of data from 2010 to 2020 will grow from 4.4 megabytes to 44 trillion megabytes, and the data center as a hub for data information resources will be under pressure.

Data shows that 35% of consumers will have smartphones in 2018, with an average of 1.4 mobile devices per person. It is expected that 90% of large corporate government agencies will use the cloud. It is also worth noting that currently 80% of malware infections have only one victim, and 99% of malware victims have fallen below 10, and the targeting of new advanced threat attacks has become more obvious. Well, for the data center to see what, with the increase in the number of smart mobile terminals, data generated by the mobile terminal will be multiplied by the day, and the cloud platform will bring greater pressure on the data center architecture, the new advanced The threat is like a hungry wolf ready to bite on the data center.

With the advent of new technologies and platforms such as cloud computing, big data, and mobile, data centers are facing more and more challenges. Although most of the technologies originally used in traditional data centers can be applied to new cloud data centers, many problems still arise. For example, security architectures cannot meet the requirements for large-scale expansion and flexible changes of the cloud. Multiple solutions It is difficult for them to coordinate and collaborate with each other. Traditional solutions do not take into account special requirements such as virtualization and on-demand deployment of cloud computing.

From the development of the traditional IT infrastructure to the current cloud era, the greatest change is in resource supply. The management and deployment of resources are generally implemented by software. Under the new service delivery mode, the role of software in coordinating and managing becomes stronger and stronger. The change made by hardware is to cooperate with software to complete this work. As hardware becomes more general and standardized, dedicated chips are gradually being replaced by general-purpose chips such as X86 or ARM. The original functions carried by hardware are more realized through software, and this brings the greatest One benefit is the improvement of efficiency. Software definition is revolutionizing the data center and revolutionizing the safe operating environment for enterprise applications.

According to Miao Tiejun, cloud security expert at VMware China Center of Excellence, in the cloud data center, the data traffic between the inside and outside of the data center is decreasing, and the data traffic inside the data center is increasing, which means that the security problems within the data center are more prominent. The emergence of the cloud led to the disappearance of the traditional security boundary and improved flexibility of resources, but the control was weakening. The multi-tenant nature of cloud computing also requires a unified management of multi-tenant security solutions. In addition, the security issues of new components introduced by software-defined data centers need to be considered.
