Best cloud computing companies

There is no neutral way to score “best”, so this list uses a number anyone can check: the revenue each company reported for its cloud business in its most recent quarter. A company moves up only when customers pay it more.

Companies report different things. Amazon and Alibaba publish a cloud segment. Microsoft lists Azure in its results. Oracle separates infrastructure from applications. CoreWeave, Cloudflare, DigitalOcean and Nebius sell little else, so their total revenue is the figure. The “Reported line” column says which one was used, and the full method covers currencies, fiscal calendars and what is left out.

Amazon Web Services reported about $46.0 billion for the third quarter of 2026, up 39% from a year earlier. Azure brought in $33.2 billion in the quarter that ended September 30, 2026, up 48%. Google Cloud reported $30.7 billion, up 103%, a figure that includes Google Workspace.

Together the three took 61% of worldwide spending on cloud infrastructure services in the third quarter, by Synergy Research Group’s estimate: Amazon 26%, Microsoft 19%, Google 16%.

Oracle’s cloud infrastructure revenue reached $7.4 billion in the quarter that ended August 31, 2026, up 121%. Its total cloud revenue, which adds applications, was $11.6 billion. Oracle also reported $664 billion in remaining performance obligations, the contracted revenue it has not yet recognized.

Alibaba reports in renminbi. Its AI Cloud and Compute Services segment made RMB 48.4 billion in the quarter that ended June 30, 2026, or US$7.14 billion by Alibaba’s own translation, up 45%.

A newer group of providers, often called neoclouds, rents GPU capacity for training and running AI models. Two of them report enough revenue to rank here. CoreWeave reported $2.58 billion for the second quarter of 2026, up 112%, with a $104 billion backlog of signed orders. Nebius reported $582.3 million for the same quarter, up 454%; that group figure includes its Avride and TripleTen businesses.

Lambda and Crusoe sell similar capacity but are private and publish no audited revenue, so they are named below without a rank. The page on AI cloud companies compares this group in more detail.

Cloudflare runs compute, storage and security services from its own global network and reported $782.5 million for the third quarter of 2026, up 39%. DigitalOcean, which sells to developers and smaller companies, reported $321 million, up 40%. Akamai is mostly a content delivery and security business; the line counted here is its cloud infrastructure services revenue, $109 million, up 34%.

Some well-known providers cannot be placed in the table without guessing.

• IBM. IBM does not publish a cloud infrastructure revenue line.
• OVHcloud. OVHcloud reports in euros, and this site does not convert currencies itself.
• Lambda. Private company. It publishes no audited revenue.
• Crusoe. Private company. It publishes no audited revenue.

Tencent Cloud and Huawei Cloud have not been reviewed yet.

Worldwide spending on cloud infrastructure services reached $168 billion in the third quarter of 2026, 55% more than a year earlier, according to Synergy Research Group figures reported by Data Center Knowledge. Amazon held 26%, Microsoft 19% and Google 16%.

Share is an analyst’s estimate and revenue is a company’s own report, so the two do not line up exactly. The market share page shows both side by side.
