Research on the cognition of distributed computing——One of the key technology of cloud computing
Qian Gong · Information technology newsletter · 2014
Parallel computing and distributed computing for cloud computing applications have new characteristics and implementation principles than in the past.Parallel computing can be divided into time in parallel and space in parallel,space in parallel has more practical value for its use of multiple processors to concurrently execute computing.The work pattern of distributed computing is that the centre server divides a large computing task into several or more task units,by the network assigns to multiple computers to complete respectively,and returns to the centre server after completing the mission.Distributed computing has comparative advantages including stronger fault tolerant ability,more flexible maintenance and higher cost performance.CAP and BASE theory which are widely concerned and very popular in modern internet are the theoretical basis of distributed NoSQL.
