AWS remains the larger disclosed cloud business. Google Cloud is smaller but has improved profitability and uses data, AI and workspace products to deepen enterprise relevance.
Amazon Web Services and Google Cloud compete for infrastructure, databases, analytics, cybersecurity and AI workloads. Their parent companies disclose cloud segments differently, so revenue and operating income are useful but not perfectly equivalent.
AWS generated about $129 billion of revenue in 2025 and operating income of roughly $45.6 billion. Google Cloud reported 2025 revenue near $58.7 billion and operating income around $13.9 billion.
Cloud growth now depends not only on computing and storage but also on AI accelerators, model platforms, developer tools, data governance and the ability to finance enormous data-centre expansion.

| Measure | AWS | Google Cloud | Reading note |
|---|---|---|---|
| Reporting period | Calendar 2025 | Calendar 2025 | Broadly aligned. |
| Revenue | About $129 billion | About $58.7 billion | Segment definitions differ. |
| Operating income | About $45.6 billion | About $13.9 billion | Both improved at scale. |
| Parent company | Amazon | Alphabet | Different capital-allocation context. |
AWS monetises a broad infrastructure and platform catalogue, partner ecosystem and long enterprise relationships. Its scale supports procurement and service breadth, while customers can also optimise spending during slower periods.
Google Cloud combines infrastructure with data analytics, AI, cybersecurity and Workspace. Alphabet’s AI research and custom chips can support differentiation, but enterprise distribution historically trailed AWS.
The stronger company can change by battleground. Distribution may favour one side, while capital efficiency, regulation or technology transition favours the other. The analysis should therefore avoid declaring a universal winner from one quarter or one headline metric.
Cloud segment revenue does not reveal contract duration, backlog quality, depreciation, internal allocations or customer concentration. Investors should pair growth with operating margin, remaining performance obligations, capital expenditure and AI-capacity utilisation.
A sensible investor or strategy team should separate operating quality from market price. An excellent business can be a poor purchase at an excessive valuation, while a weaker business can appear cheap because the market is correctly pricing structural risk. The comparison therefore stops at business analysis and does not create a buy or sell recommendation.
A comparison should be reproducible. Keep the original annual report or results release, the reporting date, the metric definition, the currency and any segment reconciliation used. For AWS and Google Cloud, record whether the figure is consolidated, standalone, segmental, adjusted or reported under GAAP or another accounting framework.
When management uses an operating measure such as bookings, order value, active clients, subscribers or ARPU, retain its definition and avoid replacing it with a similar term from the other company. That evidence prevents a visually neat table from becoming an economically false comparison.
