Cloud Environment

Public cloud environment, data encryption has become a key means to ensure data security. But when a chip needs to send or receive data stored outside of the chip, it will give the attacker an opportunity to learn about the workload and pinpoint the target. At a MIT press release on July 2, researchers brought a system called Ascend that addresses the security flaws that involve memory access. Ascend through a series of measures to minimize the attackers get from the memory data transfer process ...

Cloud computing era, led by OpenStack Cloud operating system is the highest concern, as the virtualization representative technology of cloud computing, OpenStack Cloud operating system has become the main support in the current cloud computing field. Strong security, high flexibility, good compatibility and scalability make OpenStack famous in cloud computing. As we all know, OpenStack is both a community, a project and an Open-source software that provides an operational platform or toolset for deploying the cloud. Its purpose is to help organizations run virtual computing or ...

Research on storage virtualization document encryption in cloud computing environment Zhang An with the development of network technology, especially the appearance of cloud computing, data documents will be changed from traditional local data to virtualized storage in cloud environment. In this process, the traditional data document encryption method will no longer apply to the cloud computing environment for document storage encryption. Therefore, it is necessary to put forward a new data encryption method suitable for virtual storage environment. In view of the characteristics of storage virtualization in cloud computing environment, it is proposed that the intelligent dynamic encryption and decryption will become the encryption and decryption method of the data document in the virtual storage environment.

While the benefits of cloud computing continue to be highlighted – including on-demand services that increase enterprise efficiency and control it costs, cloud security is often considered the first major obstacle to making cloud solutions widely accepted. 　　According to industry experts, many companies also hesitate to the cloud environment in the data integrity, recovery and privacy, the rules of compliance. 　　At the Gartner Security and Risk Management Summit, Verizon Business offers the following tips to protect data and network security. Evaluate your goals in deciding to relocate IT services ...

Frost & Sullivan, an IT research and consulting firm, recently predicted that the platform-service (PaaS) market would be the next area of intense competition for cloud-computing start-ups, as the two areas of infrastructure, service (IaaS) and software as services (SaaS), were already commercialized. As most of the software available from the cloud environment is standardized, organizations now expect to take full advantage of the PAAs solution, as this will be the only area where service providers can gain differentiated advantages. It is worth mentioning that PAAs this class of cloud computing services will ...

Various new cloud performance management tools and technologies will make the visibility of applications in the cloud environment clearer. 1 milliseconds is just a short moment. But if you're a SaaS provider, with thousands of databases running more than 2 billion SQL queries a day, it's very valuable to provide 10TB of SQL data. Performance is also critical to visibility-especially when your system is connected to other providers ' systems in the cloud. This is exactly what concur technology has been doing, and it is dealing with more than 50 billion dollars a year in the cloud ...

Dynamic service for large-scale data processing private cloud system Wang Zhu, Merlin, Lilei, Chang, Hu Guang Summary: In order to adapt to a private cloud environment with large amount of data, computationally intensive, complex process of computing task demand, for reference to the public cloud computing related theory and technology, combining the characteristics of private cloud environment, This paper presents an implementation scheme of a dynamic service private cloud system which adapts to large-scale data processing. This scheme uses the job file to describe the computing task, constructs the processing work flow dynamically with the job logic structure, and introduces the MapReduce parallel framework through the data stream driver service request.

Introduction: Cloud Security Alliance China Branch director Zhao Food that in the rapid development of cloud computing process, the network security concerns have been one of the industry's focus. The traditional threats remain, and new threats are constantly being uncovered. Improve the real level of cloud security protection while increasing the confidence of potential cloud users and top management.

Gemini chief Technology Officer Joe Coyle listed six questions for future IaaS vendors before choosing the IaaS vendor. For us to better grasp the situation, so as to obtain the best possible benefits for ourselves. 1. What if your cloud computing resources are not available? Although cloud computing is still fairly stable, like disaster recovery and high-availability issues in the IaaS data center, it is appropriate to find a way to target a cloud environment that can be implemented or used. ...

Another survey shows that security is a big problem for those who want to adopt cloud computing. 　　Ipswitch, a network equipment maker, asked 1000 customers whether they planned to invest in cloud technology in 2011. The good news is that more than two-thirds of customers are said to have given a positive answer. 　　The bad news is that most of what is needed is a private cloud environment (29%), or a mixed environment (21%) of a public cloud and a private cloud. No one agrees entirely with the elements of a private cloud, but it is generally agreed that a private cloud is a way to provide services like the cloud.

Research on access control technology based on negation rule in cloud computing the security and privacy protection of Wu Zhengxue data poses great challenges to the cloud computing field, and a access control technique based on negative rules is proposed to realize the sharing of some data among cooperative enterprises in a cloud environment without involving confidential information. The main idea is to prevent illegal access by judging whether the access query is authorized and whether there is conflict between the authorization and the negative rule. Theoretical analysis and experimental results show that this mechanism can effectively guarantee the security of cloud data. Research on access control technology based on negation rule in cloud computing
