The latest earnings from Microsoft, Google, and Amazon underline one clear reality: the cloud keeps growing, but even the biggest providers are struggling to keep up with demand.
Google Cloud posted $13.62 billion in revenue for the second quarter, a 32 percent year-over-year jump. CEO Sundar Pichai credited the company’s global network of AI-optimized data centers and its range of GPUs and TPUs for fueling growth.
Yet he acknowledged a challenge many rivals share: capacity is being stretched thin. To meet rising workloads, Google raised its 2025 capital spending plan by $10 billion, focusing largely on cloud infrastructure and AI.
Microsoft, which reported $46.7 billion in cloud revenue, also put capacity front and center. CEO Satya Nadella revealed the company added more than two gigawatts of new capacity over the past year, citing migrations, cloud-native applications, and AI as the main growth engines.
A standout case came from Nestle, which shifted thousands of servers and petabytes of data to Azure in what Nadella described as one of the largest successful migrations ever attempted. Despite such wins, he admitted demand still outpaces supply and expects that trend to last well into fiscal 2026.
Amazon Web Services delivered $29.3 billion in revenue, up nearly 17 percent from the year before, but echoed the same theme. CEO Andy Jassy explained that AWS could generate even more revenue if capacity were available, calling demand greater than what infrastructure can currently serve. Still, he expressed confidence in the long-term outlook, pointing out that most global IT spending remains on-premises and will gradually shift to the cloud in the coming decade.
Taken together, the three hyperscalers are enjoying massive growth yet facing a bottleneck that money and scale alone cannot instantly solve. The race to expand data center capacity, particularly for AI-driven workloads, highlights a paradox: the cloud’s biggest challenge right now is its own momentum.
