Google Cloud growth tops peers

Cloud numbers matter because they are the cleanest read on where enterprise AI is actually getting built. Not pitched, not demoed — built. And in the latest round of earnings on April 29, 2026, Google Cloud was the standout on growth, even though Amazon Web Services is still much larger and Microsoft Azure is still the default benchmark for a lot of investors. ### What happened? Alphabet said Google Cloud revenue jumped 63% year over year in the March quarter, crossing $20 billion for the first time. Microsoft said Azure and other cloud services grew 40%. Amazon said AWS grew 28% to $37.6 billion. All three were strong. But on pure growth rate, Google Cloud was the fastest of the group this quarter. ### Why is that the interesting part? Because Google is coming from behind. AWS still throws off the most revenue — $37.6 billion in the quarter — and Azure remains deeply embedded in enterprise software budgets. So Google winning the growth-rate race does not mean it has taken the market. It means the company is gaining momentum fast enough that investors have to treat it as more than a distant third. ### What is actually driving the jump? AI infrastructure, basically. Sundar Pichai said Cloud accelerated because of demand for Google’s AI products and infrastructure. He also said Google Cloud backlog nearly doubled quarter over quarter to more than $460 billion, which is a huge tell. Backlog is not booked revenue today, but it does show customers are committing to future capacity. That usually means real workloads are moving in, not just experiments. ### Is this just a Google story? Not really — it is a hyperscaler story. Microsoft said Azure growth was driven by demand across its cloud portfolio, with AI infrastructure still pulling hard enough to pressure margins as it scales capacity. Amazon said AWS just posted its fastest growth in 15 quarters and tied that acceleration directly to AI demand and a bigger custom-chip business. So the broad signal is not “Google wins.” It is “enterprise AI spending is landing in cloud revenue now.” ### Why does backlog matter so much? Because cloud investors care about durability, not one hot quarter. Google’s quarter can look flashy if customers rushed to reserve compute after a product event. But a backlog above $460 billion suggests the demand pipeline is getting sticky. That matters more than a single revenue beat, especially in AI, where the real constraint is often available capacity rather than customer interest. ### Does faster growth mean better economics? Not automatically. Microsoft explicitly said gross margin percentage in Intelligent Cloud fell because it is scaling AI infrastructure, even with efficiency gains elsewhere. Amazon’s free cash flow also got hit by a year-over-year surge in property and equipment spending tied primarily to AI. The pattern is clear — revenue is accelerating, but so is the bill for data centers, chips, networking, and power. ### So what should you take from this? The cloud race just got more interesting. Google Cloud grew fastest. AWS stayed biggest. Azure stayed formidable. The common thread is the important one — AI demand is no longer showing up mainly in narrative and capex plans. It is showing up in reported cloud revenue, backlog, and operating decisions right now. ### Bottom line? This quarter did not settle the cloud war. But it did settle one narrower question. Enterprise AI demand is real enough to move all three hyperscalers at once — and Google, at least this quarter, converted that demand into the fastest growth of the bunch.
