Amazon's cloud computing services

Its latest third-quarter earnings report reveals that sales in the cloud computing business has been the dominant impetus for profits for six straight fiscal quarters.

Cloud is a metaphor for the network and the Internet. Cloud computing, able to perform 10 trillion calculations per second, can simulate and predict climate changes and market trends.
