During the World Cup, the technology giants used big data to predict the results and reproduce the "octopus Paul". The World Cup is over but big data forecasts will continue. From the night sky to the weather forecast, from the crystal ball in the fairy tale to today's science and technology prophets, from the legends of the earthquake clouds to the earthquake predictions of the scientists ' onslaught, mankind has been hoping to break through the limits of the future. With the deepening of the information revolution, the prediction of the large data age is easier, and human life is being profoundly changed by large data predictions. Prediction is the core value of large data when people talk about the collection, storage and mining of large data, the most common ...

During the World Cup, the world's major technology giants used big data to predict the World Cup results, really let big data in the World Cup thoroughly fire. Don't think the World Cup is over, the big data forecasts will not stop.

Building a fully service-oriented system has always been the goal pursued by Twitter, and from the previous article, we shared Twitter to cope with the overall 143,000 TPS peak system overview, but the details of the various service components are not involved. Fortunately, the company recently disclosed Manhattan's independently developed database system, which delivers in-service features while delivering features such as high availability and availability. The following is translation: As Twitter grows into a global user exchange ...

Will our future be in the hands of big data? As long as we encounter incomprehensible things, we will say that it is accidental, it seems that this seemingly accidental action has contributed to the evolution of history, and the twists and turns of things seems to be like the dice. But what does this chance really mean? And French mathematician Poisson points out that once we admit that human behavior is the most random, it can suddenly be predicted. Paradox? In fact, one of the most appropriate examples is the dice: Although the number of points can not be predicted each time, but the overall law can follow. That is, about 5 to 7 of each throw ...

The private cloud is another widely used application of cloud computing since the public cloud. Private cloud performance monitoring plays an important role in not only diagnosing failures, but also making a contribution to ensuring that service levels meet the needs of centralized services. To ensure success, smart IT staff often create efficient virtualization strategies to perform performance monitoring for private clouds. Continuous collection of private cloud performance monitoring data The private cloud is about processes, automation, people management, and consolidation. Some private clouds use virtualization technology and physical host hosts, so no matter what kind of tool you use ...
