In Memory Data Grid Architecture

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

In fact.   　　 Cloud computing technology is the combination of software SaaS, Grid computing, virtualization three concepts. Virtualization of Cloud Computing Technology (virtualization) virtualization is the virtualization of infrastructure (virtualization), the core of which is the combination of traditional mature cluster technology and partitioning technology. Cluster computing (Cluster comput ...

Zhang Fubo: The following part of the forum is mainly four guests, talk about cloud practice. Beijing First Letter Group is the Beijing government's integration company, mainly responsible for the capital window of the construction, they are also in the domestic, in the government industry earlier in a company, as the first letter Group Technical Support Center General Manager Zhang Ninglai for us to do the report. Zhang: Good afternoon, we have just introduced, I am from Beijing First Letter Development Co., Ltd., I bring today is the result of our practice in cloud computing technology these years. Today is mainly divided into three parts, we mainly do is the field of e-government applications, we are mainly ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

Recently, the Beijing Cloud computing Industry Development Symposium was held in Beijing by Changfeng Alliance, and industry experts from industry and Research have discussed the development and standard of cloud computing. 　　Here are some ideas and views from various experts on cloud computing. It is understood that the nature of cloud computing is the pursuit of lower cost, more resources to save or resources more efficient, faster. 　　So what is cloud computing? What are the elements of cloud computing? Where is the boundary? What is the ultimate value for an enterprise application? CAS Par ...

The amount of data used for SaaS applications is facing a TB-level growth rate, with different SaaS applications, and not exactly the same data structure, with text, graphics, and even small databases. 　　With the distributed characteristics of the cloud service platform, the SaaS application data can be distributed on different servers, and how to data mining the heterogeneous data is a difficult problem faced by the enterprises in cloud era. The challenge of enterprise data mining in cloud era mining efficiency: After entering the cloud computing era, BI's thinking has been transformed. Previously based on closed enterprise data Mining ...

Introduction: Now More and more public emergencies, especially such as man-made emergencies, such as the recent Stampede events in Shanghai, the Internet or large data, can play some positive energy role? To prevent the recurrence of such tragedies? This session of the IT Hall of Fame is the founder of star Ring Technology, Mr. Sun Yuanhao, and we had an exclusive interview at the 2015 China Hadoop Technology Summit. Sun Yuanhao that, can use some new technical means to detect the change of Waitan flow of people, for the public Security departments and transport departments to provide some information guidance, such as photo ...

Innovative report from the dean of top research institutes when all our actions and our lives can be "data", the company that holds the data is like owning a rich gold mountain. 　　As Victor Maire-Schoenberg says, the big data age is "the future that has happened," and in this already-occurring future, there is no bystander. December 19, 2013, by the boutique media "digital Business Times" sponsored by the "Great data creation of the era of Subversion" 2013 China Summit Forum in Beijing to make a grand Holiday Crowne Plaza Hotel ...

First, the initial understanding of large data seems to be overnight, big data becomes one of the most fashionable words in the IT industry. First of all, big data is not a completely new thing, Google's search service is a typical large data use, according to customer demand, Google real-time from the global mass of digital assets (or digital garbage) ...

The big data age is putting pressure on data storage, and more and more organizations need to build a storage platform that can store large amounts of structured and unstructured data on the basis of cloud computing technology. 　　Cloud storage should be "cloud"-born. The so-called cloud storage, refers to through the cluster application, grid technology or Distributed file system functions, the network of a large number of different types of storage devices through the application software together to work together to provide data storage and business access functions of a system. The key to implementing cloud storage that adapts to user needs is to choose a strong data architecture based on application and deployment requirements ...
