Blockchain is currently a relatively popular new concept, containing two concepts of technology and finance. From a technical point of view, this is a distributed database that sacrifices consistency efficiency and guarantees eventual consistency. Of course, this is one-sided. From an economic point of view, this kind of fault-tolerant peer-to-peer network just meets a necessary requirement of the sharing economy - a low-cost trusted environment.

"Silicon Valley net November 4," according to the 16th issue of the 2012 edition of "Silicon Valley" magazine, the paper describes the definition, classification, supporting technology and architecture of cloud computing by using the method of literature analysis, and introduces the research status and some technical solutions of cloud computing related technologies from the aspects of Computing architecture, programming model and 　　Looking forward to the development trend of cloud computing, it can provide reference for the research of cloud computing. Keywords: cloud computing, parallel computing, virtualization, on-demand use of 0 introduction cloud computing (cloudcomputing) was born in the 3rd quarter of 2007 ...

Overview The key information maintained by the control plane is the network state. The control plane must aggregate this information and make it available to the application. In addition, in order to maintain scalability and component reuse, applications should be exempt from protocol details, even though network state information is obtained through a specific protocol. The Onos topology of the protocol is implemented by two complementary mechanisms: Network Discovery and configuration. The former uses the network protocol to let Onos identify the location and/or performance of the network elements, and take the initiative to carry out the relevant collection work when the function is enabled. The latter allows applications and operations ...

"Editor's note" Mature, universal let Hadoop won large data players love, even before the advent of yarn, in the flow-processing framework, the many institutions are still widely used in the offline processing. Using Mesos,mapreduce for new life, yarn provides a better resource manager, allowing the storm stream-processing framework to run on the Hadoop cluster, but don't forget that Hadoop has a far more mature community than Mesos. From the rise to the decline and the rise, the elephant carrying large data has been more ...

This article builds a simple demo application by using Watson Question and Answer (q&a) technology and the Q&a APIs exposed by Watson. Watson Films. Cognition exists in almost any activity that human beings do, such as language comprehension, sensation, judgment, athletic skills, learning, spatial processing and social behavior. We are increasingly expected to use machines that exhibit the same cognitive behavior. IBM Watson stands for the cognitive system (a new gauge ...).

Server08 R2 is the cloud mainstream operating system 2012, the development of cloud computing has begun to descend slowly, after all, the ultimate goal of cloud computing is to bring profits to the business, to bring convenience to people's lives, illusory things even if the outline of the perfect will be eliminated.   In 2012, cloud computing has begun to solve the real problem for users, the major IT vendors have launched their own cloud solutions, it can be said that the next step of cloud computing will usher in a real test, but also the cloud is ushered in a rapid landing opportunities. ...

In the face of the changing social economy, the tax industry needs to understand the relevant information of taxpayers in a real and comprehensive way, and to promote the internal aggregation and sharing of tax data, so the tax data is the core resource of the tax industry, so it can realize the transformation of the data to the service, and use the resources that It is the best way to improve the efficiency of tax industry to realize the tax informatization by providing the cloud computing to the audience in the form of service. For complex and difficult to co-ordinate tax data, cloud computing can not only achieve data collection and sharing in the tax industry, but also can help tax authorities to convert data into service ...

The current network of telecom operators can be divided into three categories, namely, the main business, base operations, long tail and SP business. 　The main business includes the application of SMS, MMS and other telecommunications applications, including the current operators of music, video, animation base and so on, long tail business and SP business mainly includes the Internet class and the application of cooperative class. The main problems of current business system are: vertical construction of main business platform, continuous investment, small amount of existing SP business, low utilization of equipment, inability to share, long tail business development and operation cost is high, can not form effective contribution; Base business respective construction, content cannot ...

The main problems of current business system are: vertical construction of main business platform, continuous investment, small amount of existing SP business, low utilization of equipment, inability to share, long tail business development and operation cost is high, can not form an effective contribution; base business construction, content can not be shared, user information can not be shared. 　　 　　If the traditional business network architecture, these problems can not be fundamentally resolved, and the rise of cloud computing technology has brought us a glimmer of light. Telecom business pooling and virtualization technology has experienced more than more than 10 years of development, technology has been more mature. and Cloud tube ...
