Worldwide end-user spending on public cloud services is forecast to total $723.4 billion in 2025, up from $595.7 billion in 2024, according to the latest forecast from Gartner, Inc.
“The use of AI technologies in IT and business operations is unabatedly accelerating the role of cloud computing in supporting business operations and outcomes,” said Sid Nag, Vice President Analyst at Gartner. “Cloud use cases continue to expand with increasing focus on distributed, hybrid, cloud-native, and multicloud environments supported by a cross-cloud framework, making the public cloud services market achieve a 21.5% growth in 2025.”
Gartner predicts that 90% of organizations will adopt a hybrid cloud approach through 2027, and the most urgent GenAI challenge necessary to address over the next year will be data synchronization across the hybrid cloud environment.
Overall, all segments of the cloud market are expected to record a double-digit growth rate in 2025 highlighting how I&O leaders are pressured to effectively integrate I&O into their GenAI strategies and prepare for running AI and GenAI infrastructure at the edge (see Table 1).
