Aug 1 (Reuters) - Amazon.com ( AMZN ) forecast

current-quarter revenue largely below Wall Street estimates on

Thursday, signaling tepid demand for its cloud computing

services as businesses keep a tight lid on costs against an

uncertain economic backdrop.

The company expects revenue of $154.0 billion to $158.5

billion for the third quarter, compared with analysts' average

estimate of $158.24 billion, according to LSEG data.
