Amazon on Thursday reported profits in the past quarter jumped 12-fold to $2.5 billion as the online giant saw gains across its range of businesses.

The stronger-than-expected profit helped boost Amazon shares 2.4 percent in after-hours trading even though its revenue increase came in short of forecasts, rising 39 percent to $52.9 billion.

Amazon has grown into one of the world's biggest companies on its global e-commerce operations along with cloud computing, artificial intelligence, video, groceries and other operations.
