As a new mode of information communication, cloud communication has the basic characteristics of network communication, and has the characteristics of mobility, location, ubiquitous, real-time and large data. Cloud communication is a mechanism for people to transmit and share information in cloud computing environment, and its intension can be defined from three levels. First, cloud computing can push the internet and the mobile internet into a "interconnected cloud", the nature of cloud communication is the flow of information in the "interconnected cloud"; second, the user only needs to obtain services according to their own requirements, without having to care about who provided the service, and can release it again after use ...

Before 2013, there may be a wait-and-see or scepticism about the cloud, but after a year of development, cloud computing has completely landed: Big companies are busy with how to deliver faster, more stable and safer cloud services, how to snatch users in the cloud market, and small companies to consider how to use cloud computing to reduce their operating costs. How to make your system into a cloud structure; startups think about how to use the cloud to reduce upfront spending, and even how to use the concept of "cloud" to start a business and sell yourself in front of a VC. According to Gartner, 2013 Global ...

A dense algorithm for mobile data terminals based on elastic cloud computing Huang A new intensive algorithm based on elastic cloud computing, which makes mobile data terminals use computing resources of cloud efficiently and conveniently, and reduce the resource demand of mobile data terminals. This paper focuses on the application segmentation algorithm of computing migration combined with cloud computing, and presents a maximum flow minimum tangent algorithm based on elastic cloud computing. Experiments show that the algorithm can effectively improve the computing ability of mobile data terminals and reduce the energy consumption of equipment. A dense algorithm for mobile data terminals based on flexible cloud computing

Infrastructure integration in cloud computing environment Wang Lijiang Hyper Cloud computing is the innovation of service mode, which brings more efficiency and scalability to users, and is the change of the whole it field. This article describes the relevant technologies and solutions around the cloud computing infrastructure. Keywords: infrastructure; cloud computing; virtualization; infrastructure integration in cloud computing environment

Large data dominate the current technology news, and it is touted as a possible solution to all problems, from intrusion detection and fraud prevention to cancer treatment and the setting of optimal product prices. But we define large amounts, multiple formats, and high speed data that are not the panacea for every problem. 　　In fact, if the company superstitions around some of the big data myths, it may go further in the wrong direction, wasting a lot of time and money, affecting the company's market competitive position, or damaging the company's reputation. The following is the enterprise should know the surrounding ...

Cloud computing brings a lot of new jobs to the world, but also spawned a large number of training and certification agencies, the major mainstream cloud computing companies will certainly not miss this opportunity to launch their own cloud computing certification. Now the global enterprise annual demand for cloud computing talent is showing a sharp upward trend, while the major enterprises are difficult to recruit the right cloud talent, which is mainly due to lack of training and certification, Coudbusinessreview website of Mary DeSilva here to introduce more influential cloud certification in the field of cloud computing, the hope for large ...

Large data research 严霄 Phoenix Zhang Dexin Large data is after the cloud computing, the Internet of things after the IT industry again subversive technology revolution. Large data mining and applications can create trillions of dollars worth and will be one of the largest market opportunities in the IT field in the future. Large data utilization puts forward higher requirements for real-time and effectiveness of data processing, and it needs to transform traditional conventional data processing technology according to the characteristics of large data, and form a technology suitable for large data collection, storage, management, processing, analysis, sharing and visualization. This paper introduces the concept of large data and its key technology,...

The upcoming Stardog 2.1 query scalability improves by about 3 orders of magnitude and can handle 50 billion triple on a 10,000-dollar server. We have never focused too much on stardog scalability itself: we first consider its ease of use and then consider its speed. We just assumed it would make it extremely scalable. Stardog 2.1 makes querying, data loading, and scalability a huge leap forward. Run S on a 10,000 dollar server hardware (32 cores, 256 GB RAM).

With the advent of the new Year, the focus of OpenStack development will be shifted to address the bottleneck that prevents enterprises from implementing open source cloud computing platforms. OpenStack developers have developed projects that mitigate the usability and scalability problems of the system, as well as provide OpenStack enterprise production instances, although these projects are still in the incubation period or have just been released recently. Among them, the most prominent project is a project called Tripleo, this project also has an alias--openstack opens ...

A dynamic cache partitioning method for virtual machines based on hot page migration Wang Xiaolin Hushamo Li Ye Luoyingwei static cache partitioning can reduce the cache conflicts generated by parallel programs, and increase the total performance of cache polluters and cache-sensitive programs running in a multi-core processor with a shared minimum cache. In a virtualized system, different programs run on different virtual machines at different times, so it is not appropriate to statically partition the cache beforehand. In this paper, a dynamic cache partitioning strategy is proposed, which utilizes the thermal page monitoring mechanism and page migration technology to cache the prior letter of the sensitive program.
