Bending Comments Chen Huai Lin: SDN is cloud security opportunities

Cloud security

According to the TechTarget China Cloud Security Survey 2012, 79.6% of enterprises are currently conducting or considering cloud services, but when it comes to cloud computing security, respondents who think cloud computing is secure and unsafe are basically the same 51.9% (safe) and 48.1% (unsafe). Cloud security is still the most important reason that businesses can not get into the cloud with peace of mind. In the long run, even if cloud computing continues to become popular, many enterprises do not trust themselves to put all their workload in the public cloud. They will still have an in-house deployment. At the 2012 Cloud World Congress, TechTarget Chinese correspondent held dialogue with renowned technical expert Chen Huailin on cloud security issues.

Chen Huai-lin said: "Privacy protection is indeed a big concern for people because different places have different legal governance information, and improper protection can cause serious consequences." The problem is that the data is not physically stored in the cloud Computing environment on any one computer, but distributed on numerous machines, so there is no fixed physical location to check.

At the same time, Chen Huai-lin also introduced a report on the related issues of the U.S. Academy of Engineering last year, which introduced the concerns of enterprises regarding the data transfer to the cloud. Chen Huailin said humorously: "The bosses do not understand technology and only have money. Cloud migration is not a one-time event, but storage in general enterprises still have to put their own business, some computing and some peripheral applications will be put into the cloud, the core application is still not suitable for entering the cloud.But overall, for some For businesses, cloud security is a big opportunity. "

SDN and OpenFlow

On-demand cloud services are built on a complex infrastructure that includes physical and virtual resources that may span multiple clouds. These environments need to be precisely configured to support efficient and reliable service delivery. Especially in the configuration and management of networks and data centers, SDN is likely to be the glue to repair all these challenges. SDN allows users to manage these networks through a single unified framework.

Chen Huai-Lin believes that SDN's first application may be said that in the area of ​​security, but also an actual opportunity to improve cloud network security. The SDN Controller has a global view of the network. This comprehensive view and network intelligence at the edge of the network combine to provide new opportunities for this controller to monitor the entire system and enforce security policies. The SDN architecture extracts the control plane from the topology of the physical network to create an environment in which switches, routers, and other network devices forward instructions from an all-encompassing, centralized controller rather than making their own decisions on each device. Because an SDN controller monitors the capacity and resource requirements, it can be programmed to move workloads between competency-based resources.

With technologies like OpenFlow, SDN is likely to become a big cloud automation enabler. Cloud computing providers can use SDN to automate the cloud provisioning process so that resources, including bandwidth, can be turned on and down as needed. For example, OpenFlow-based load balancers deliver real-time data into their libraries based on "available capacity" data that automatically diverts traffic between virtual machines or even between different clouds. By design, these controller-based applications are more adaptable, scalable, and efficient than traditional appliances that rely on more static functions to complete the process. SDN is useful for workload transfer across and across clouds.

Cloud management

Currently, the competition in the cloud management market is getting fiercer and fiercer. All major IT vendors are gearing up for cloud administration. According to IDC research, the global cloud management software market is expected to reach 2.5 billion U.S. dollars in 2015. For the major vendors, cloud management is an opportunity to build long-term, strategic relationships with customers. For emerging vendors, cloud computing is also important for its product development and offering of SaaS solutions to a broader cloud management environment.

Chen Huai Lin introduced the current Silicon Valley's major venture capital VC are concerned about the field of cloud management startups, as the focus of cloud construction from the data center to the public cloud, private cloud, hybrid cloud and other types of cloud operation transition, the corresponding management tasks It has also shifted from the management of the data center to the management of the cloud. The best path to cloud management begins with data center management, consolidating the underlying resources, provisioning with virtualization and automation, and eventually transitioning to cloud services.

In addition, as early stage enterprises pay more attention to the development and deployment of private cloud, they gradually face the connection with public cloud. The trend of hybrid cloud management will be more and more obvious whether it is a third-party provider or a partner cloud. Increasingly. Hybrid cloud management is responsible for managing network and storage resources across multiple domains. Over time, the mix of domains will change, but management policies and tools will remain the same.
