Cloud computing: A public and private dilemma

Cloud computing is a way of thinking about IT infrastructure as a service. Depending on the nature of cloud computing services, cloud computing can be differentiated into public, private, and mixed clouds. At present, there are many cases of cloud computing in our country, and more than 10 cloud computing centers are coming into operation.

However, the majority of successful cases are based on the enterprise private cloud. For a private cloud, the transition from the current enterprise's IT infrastructure to the private cloud computing paradigm takes several steps, first through virtualization to create a virtual machine, and then by implementing a virtual machine that migrates to different physical servers, ultimately enabling the system to dynamically allocate resources. There is also a need to provide self-service portals that allow users to easily customize the resources they need, and to measure the resources allocated in the background. is relatively easy to accept.

Because the private cloud is typically within a firewall, providing operational services for an enterprise, it is more secure, compliant, and quality of service, and easier to integrate existing applications and reduce operating costs.

Although the public cloud cost is lower, the management burden is lighter, in the aspect and so on capacity allocation has the superiority. But the cost of openness is the risk of a variety of security. In the shared "cloud", it is important to protect the security and privacy of the data. This is an important issue to consider before the cloud lands. About the security of the cloud, is the data to be managed, or to be safe? Only by ensuring the security of data can the cloud be more open and efficient. So, in data management, better protection is needed to make data more widely available.

So, for the public cloud, security is the main challenge. Many companies are not comfortable keeping their data and applications in a system they cannot control. They argue that migrating workloads to a shared architecture increases the potential risk of unauthorized access and information disclosure. Therefore, consistency requirements around authentication, identity management, compliance, and access technologies become more important.

This requires cloud computing providers to prevent unauthorized access and information disclosure by effectively encrypting customer data. Cloud computing service providers in the choice of cloud computing platform, especially the need to pay attention to the security of cloud computing platform, in particular, some core areas of data security related to national security, related to business Lifeline business data, based on an autonomous and controllable "cloud computing environment" is very important.

In fact, the choice of public, or private, the answer is not difficult to find. Private cloud has a private cloud of relative security and cost of high walls, public clouds have the public cloud is willing to Tianjin road price advantage and security weakness. To put security first the enterprise IT decision-makers are more concerned about the private cloud, the security is not the main factor in the application and data, the public cloud is still full of charm. Public clouds are the ideal choice for sudden applications that require maximum computational power and minimum storage time.

There is no doubt that the cornerstone of the future public cloud services, over time, private cloud and public cloud resources will be mixed or interleaved. Whether it's a private cloud or a public cloud, it's just a possible path for an enterprise to realize informatization. As long as we can solve the problems faced by enterprises, as long as can improve the productivity of enterprises and production efficiency, as long as the enterprise has the best TCO, is the ultimate enterprise to seek.
