Data mining is more complex than information search. Massive data processing to achieve high- performance machine or large-scale computing devices, cloud computing-based data mining to better achieve their goals. The cloud computing model has many advantages, low cost, fault tolerance, the calculation speed; convenient program development nodes increase more easily. Can be said that cloud computing is generally applicable to data mining is more ideal computing model, from huge amounts of data to find useful and understandable knowledge of the technical means.
