Cloud Services Market Hits $68 Billion In Q3 2023

Worldwide enterprise spending on cloud infrastructure services—which many of the cloud startups on CRN’s list provide—reached a record $68 billion in third-quarter 2023.

This represented global growth of $10.5 billion year over year as generative AI demands and services continue to thwart any economic disruption.

“For the last three quarters the market grew by around $10 billion compared with 2022. In Q3 that incremental annual growth nudged up to $10.5 billion. Take a bow, AI,” said John Dinsdale, chief analyst and managing director at Synergy Research Group. “As an already massive cloud market keeps on growing, the year-on-year growth rate almost inevitably declines. But we are now starting to see a stabilization of growth rates, as cloud provider investments in generative AI technology help to further boost enterprise spending on cloud services. It is still early days for generative AI, but the technology will help to keep cloud growth buoyant over the coming years.”

The growing need for new cloud platforms, AI-powered cloud offerings, cybersecurity, public cloud management and services is being met head-on by these innovative startups. Click through for an in-depth look at the 10 coolest cloud computing startups of 2023:
