Brief Introduction
Flink is a distributed engine based on streaming computing, formerly known as Stratosphere, which began in 2010 at a university in Germany, and has a history of several years, drawing on the ideas of other projects in the community for 2014 of years, rapidly developing and entering the Apache top incubator.
Spark supports batch and stream calculations (cutting streams into small batches) at the bottom of the batch, and the Flink su
This thing gives me a headache. I know that cloud computing is very important and is being pushed into the plans of various corporate governments. But I always think cloud this dongdong and the familiar system compare. It seems to be a short cut. Of course, perhaps because it is still in the early stages of development. There are a few words to sum up about its flaws:
1. It has made full use of hardware resources, and it has also consumed a considerab
A few times when our team walked through the street night market, see the ground on a variety of small commodities, there is the iphone's foil, mobile phone shell, of course, there are a variety of memory and 8G/16GB small flash drive, this time there will always be someone shouted: "Look!" Memory computing age has come! "While this does not accurately express the advent of the memory computing age, this is
Questions raised:
With the rise of cloud computing and the Internet of things, the internet is increasingly "urbanized", the traditional courtyard (metropolitan area Network) is being replaced by skyscrapers (cloud Computing data Center), just formed soon the "global village" quickly developed into "Earth City", the Internet of Things is the "city" of all the goods information, The real world and the virtu

Today, cloud computing has become a hot topic. The form of cloud brings new application methods. Enterprise Users no longer need to invest heavily in building their own data centers to deploy large applications, you do not need to consider equipment selection and procurement, or even have your own O M personnel 24 hours a day, you only need to spend a little money to purchase the corresponding cloud computing

Although some people have rejected the concept of cloud computing in the past few years, with the continuous technological advances in the past few years, we have gradually accepted this concept. At present, a group of well-known enterprises have invested in cloud computing development and other fields, and the cloud computing development work has become increasi
In order to achieve this new model of cloud computing, it is necessary to develop an interoperability of IT management standards, while the Open virtualization Format (OVF) standards for this work provides a good foundation.

Cloud computing is now rage, as Ben Pring, a senior analyst at Gartner Consulting, said: "Cloud computing has become a hot topic for everyone." But the problem is that everyone seems to have a different definition.
"Cloud" is a familiar noun, but when it is combined with "computation", its meaning evolves in generalities and nothingness. Some analysts and vendors define cloud
With one eye and one gesture, you can control all the smart terminal devices to achieve accessibility to human-computer interaction. AMD's computation will turn this dream into reality and redefine the future of computation.
In a 360-degree dome theater, a group of animated monsters are playing various types of musical instruments, and you can use gestures to control the actions of these monsters. This is not a fantasy, but amd uses advanced surround technology to create a surround house, which
Cloud computing is regarded as an industrial revolution in the IT industry. It will bring about fundamental changes in working methods and business models. In particular, the Chinese mainland is now in a period of rapid Internet development and convergence, and cloud computing has brought unlimited business opportunities to major manufacturers. Of course, major manufacturers will not miss this opportunity a
"I remember that in the 1996, when we were promoting Internet applications in Hong Kong, I could not think of 12 years from now, the work life of each of us is inseparable from the Internet." Today, I am in Beijing to promote cloud computing, do not know what will be 12 years later? June 24, 2008, Zhou Weixian, chairman of the International Commercial Machinery Company (IBM), said at the launch of IBM's Greater China Area Cloud
Features of cloud computing
Although the industry has not yet reached a consensus on how to define cloud computing, there have been many in-depth discussions on the characteristics of cloud computing. To determine whether a computing service is a cloud computing service, you
