In the UK, big data has long been more than just a hot new term in a science forum, with a growing number of government-invested, already-running university data research centers, and a growing business effort, which clearly shows that Britain is opening up an era of big data technology. The government has made big data a "new economic growth point" in recent years, the UK economy has been in a slump and the weak economy has strained government spending. Under such a severe financial background, the British government is more eager to strengthen the country's international competition by supporting the development of new hi-tech technology.

During my hackbright mentor, I was asked to explain the mapreduce algorithm to students with limited technical backgrounds, so I came up with an interesting example to illustrate how it works. Example you want to count the number of spades in a stack of cards. 　　The intuitive way is to have a single check and count out how many are spades. The MapReduce method is: Assign this stack to all players in this room and let each player count the number of spades in their hands, and then report this number to you. You tell all the players ...

Guide: Cloud computing is not so much a technological innovation as a revolutionary force.
