On the five reasons of preventing public cloud from fast distribution

Cloud computing currently in China has undergone a period of development, the government and some it manufacturers, has been in the cloud computing landed on the actual operation. But there are still many questions about cloud computing services, the lack of corporate planning, the future of business models, management models lack of mature consideration of the people are not a few. But at the same time holding "cloud services, especially the public cloud, to save costs, small and medium-sized enterprises more affordable" view is also significant.

According to ESG's survey of the impact of the public cloud on the company over the next 5 years, 13% of the companies said the impact would be significant, and the companies already had a set of shaping strategies to use a lot of cloud computing services. The proportion of companies that do not have a full impact is 14%, and these companies are not planning to use cloud computing services for the next five years. The proportion of the moderately affected, which accounts for more than 42%, says it will deploy some cloud services strategically, which will also lead to some changes in the company's IT infrastructure and processes.

In a comprehensive way, the main factors hindering the rapid distribution of public cloud are:

1. Limited virtualization technology applications, insufficient broadband Internet access, and integration issues have hampered the use of public and private clouds.

Virtualization technology makes cloud computing possible, according to a survey of China's cloud computing published by Accenture. China's IT managers say the widespread use of virtualization is the main driving force behind the introduction of cloud computing, and it is equally important for the top leaders to believe that cloud computing will indeed slash costs. But only a handful of Chinese companies have introduced virtualization compared with other countries in the US.

At the same time, China lacks a broadband network that can support cloud computing across the country. Although China is far ahead of broadband penetration, 94.3% of Chinese Internet users use broadband access, but most users do not reach 4Mbps downloads, much lower than the average speed of 17.3Mbps in developed countries.

2. Security, which has been a suspect since the advent of cloud computing. Security is the main challenge for the public cloud. 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.

3. The threat of public cloud to employee positions is often the topic of cloud computing that will affect the employment of existing IT staff at the beginning of the cloud computing debate. While this kind of discussion has weakened, it is still one of the things that enterprise IT departments are resistant to cloud computing.

4. Immature cloud markets can only provide limited services and a few trustworthy vendors.

Nearly 2/3 per cent of Chinese respondents (almost all of them) said that Chinese corporate leaders generally believed the cloud market was premature, a huge impediment to cloud computing, according to a survey of China's cloud computing published by Accenture. But because of concerns about cloud service reliability and data sensitivity, Chinese companies are particularly wary of foreign cloud providers or start-ups. It is also reluctant to entrust data to foreign cloud providers.

5. The financial departments of most enterprises are unwilling to change the procurement process.

Before cloud computing, the financial department of an enterprise has adapted and become accustomed to the IT software procurement model. But after the adoption of cloud computing, the traditional mode is no longer used, the Finance Department has to accept and learn the cloud computing procurement model. At present, cloud computing providers offer three payment models, which are paid by users, billed by usage, and billed as transactions. Whichever model is used, the finance department has to redesign the procurement process.
