China's cloud computing faces five major challenges: insufficient user awareness

Although we can see from the "China Cloud computing Trends" analysis of the broad prospects of cloud computing at home, but also have to face the reality that cloud computing needs to deal with a number of objective challenges, can gradually develop into a mainstream structure. The challenges facing cloud computing include:

Lack of user awareness

Although cloud computing has been widely publicized in the country, several typical users and cases have emerged. But businesses and end users still lack understanding and understanding of cloud computing, especially in specific businesses and applications, and it's still not clear what changes and benefits cloud computing can bring. In this case, cloud computing really landed into a successful application, will encounter many difficulties. Therefore, the most important is to put aside a large number of theories and concepts, in the application and business aspects of marketing and user education, so that cloud computing is operable.

Hardware migration risk

An important feature of cloud computing is that it changes traditional application delivery and changes the traditional data center operations model. This change is bound to bring a certain degree of risk. This risk includes hardware migration risk and application migration risk. Hardware migration risk refers to the fact that in traditional data centers, hardware is relatively independent, but in the cloud computing hub, virtualization based patterns can lead to less obvious hardware boundaries and flexible migration of hardware devices in the form of virtual machines, in line with the principles of load balancing and increased utilization. This challenge to the traditional hardware deployment, if the lack of systematic evaluation and scientific analysis, will lead to the hardware platform can not play its due performance, and even lead to the collapse of the application system.

Apply transplant risk

The application of migration risk refers to the original application, such as financial application, ERP application, CRM application, in the traditional data center is deployed in a relatively independent hardware system, including storage will have some application independence. In the new cloud computing platform, the application will be deployed to different hardware, even the operating system, whether the application of seamless migration, is to ensure the success of the calculation of the important content. If virtualization technology is widely used on cloud computing platforms, it will involve virtual machine migration and operating system compatibility, and this factor will also affect the usability of the application.

Security

The security of cloud computing platform is composed of two aspects. One is the confidentiality and security of the data itself, because the cloud computing platform, especially the public cloud computing platform is an important feature of openness, a variety of applications integrated on a platform, the data leakage and data integrity concerns are the cloud computing platform to solve the problem. This requires a reasonable and rigorous design from the software solution and the application of the planning perspective. The second is the security of the software and hardware on the data platform, if the application data loss due to the fault or hardware crash will reduce the efficiency of the cloud computing platform. This requires the use of reliable system monitoring, disaster recovery mechanisms to ensure the safe operation of hardware and software systems.

Service Level agreement

The challenge of cloud computing is also important, in addition to the systemic risks, of how to provide users with the required services. Because compared to traditional data centers, although the services provided by cloud computing are richer, they can also give users an unmanageable worry, and by analyzing their needs, a reasonable and enforceable service level agreement (SLA) will help users build confidence in cloud computing services to a large extent.
