In the internet world three years ago, it may not know what is "cloud", "cloud", "cloud storage", but with the rapid development of information technology, many commercial applications in today's online world have been stored, transmitted and downloaded by the concept of cloud. In a large-scale development of virtual products at the same time, it is obvious that security issues will inevitably get more and more people's attention.

According to the survey, 69% of respondents were willing to deploy data, applications or infrastructure on private clouds, while 59% per cent preferred to deploy them on public clouds. The average number of deployments of an enterprise IT environment on a private cloud is twice times the deployment of the IT environment on a public cloud, with a ratio of 28% and 14%, respectively. Only 28% of respondents used the community cloud (Community Cloud), the most common use being education and browsing for High-tech information.

In fact, security concerns are paramount in the deployment of the cloud, especially for public cloud services. 2/3 of those surveyed (67%) It is considered that the safety factor is one of the three major concerns of users, and the second is the integration Problem (46%). For large enterprises, information security is more important.

Due to the maturity of cloud computing, the internal resources of the current data center are being continuously virtualized. Many data center construction people use the virtualization technology to excavate the traditional physical computing environment more potential, achieve the goal of maximizing resource utilization, reduce the cost of construction and operation. While virtualization has become a major trend in computing and storage resources and has begun to scale up, most of them still use traditional security solutions to address the current threat situation, but this will undoubtedly increase operational complexity, reduce host performance, and virtual machine density. These results in the inability to fully utilize virtualization and cloud computing technologies to maximize ROI.
