Cloud hangs over U.S. chipmakers on worries data centre growth could slow

Big Tech has reported slower annual cloud revenue growth rates this earnings season

Analysts say the cloud market has rarely had to weather a prolonged economic downturn since it rose to prominence in the last decade as more businesses adopted the technology, making it harder to predict if it's recession proof or it will be hit in an economic downtown.

As 40-year-high inflation weighs on consumers and economists debate recession signals, advertisers have been tightening their purse strings, say Big Tech companies.

“Investors are worried it's the next shoe to drop," said Bernstein analyst Stacy Rasgon, adding that an advertising drought hurting the likes of Facebook and Snapchat could spur cutbacks in data center investments.

Big Tech has reported slower annual cloud revenue growth rates this earnings season - Alphabet Inc's Google Cloud dropped over 8 percentage points, Microsoft Corp's Azure dropped 6 percentage points, and Amazon.com's AWS dropped over 3 percentage points compared with the previous quarter.

Nathaniel Harmon research director of YipitData said the revenue growth of the cloud market was still significant, although noted there were pockets of weakness in regions like Europe creeping in.
