下面给你一份按“类型/地域/定位”梳理的云计算服务商速览（以公有云 IaaS/PaaS 为主，兼顾边缘与 AI 专用云）：

全球超大规模（Hyperscalers）

• AWS（Amazon Web Services）、Microsoft Azure、Google Cloud——全球覆盖最广、服务最全，是大多数企业上云的优先候选。([Amazon Web Services, Inc.][1], [微软 Azure][2], [Google Cloud][3])
  说明：近年的市场份额长期由这三家领跑。([Statista][4])

全球“第二梯队”与特定优势云

• Oracle Cloud (OCI)：以企业数据库与分布式/主权云方案见长，全球多区域布局。([oracle.com][5])
• IBM Cloud：提供公有云与专有/联邦场景，擅长混合与行业合规。([IBM][6])

中国与亚太主力云

• 阿里云 (Alibaba Cloud)、腾讯云 (Tencent Cloud)、华为云 (HUAWEI CLOUD)、百度智能云——覆盖 IaaS/PaaS/AI 全栈，在中国及出海业务中应用广。([阿里云][7], [tencentcloud.com][8], [huaweicloud.com][9], [intl.cloud.baidu.com][10])

欧洲/主权与本地化云

• OVHcloud（法国）：欧洲领先的公有云与主权云提供商，在欧/美/亚均有区域与可用区。([OVHcloud][11], [OVHcloud][12])
• （亦可关注：Scaleway、Open Telekom Cloud 等区域性供应商。）([fastly.com][13], [docs.digitalocean.com][14])

开发者友好/中小企业取向 & 独立云

• DigitalOcean：简单易用、成本友好；其 Paperspace AI/GPU 能力已整合到 DigitalOcean 体系。([docs.digitalocean.com][15], [DigitalOcean][16])
• Akamai Connected Cloud（原 Linode 并入）：侧重分布式/边缘+计算的“互联云”。([Akamai][17])
• Vultr 等独立云也提供弹性计算与网络产品。([irqm.com][18])

边缘/无服务器（Serverless at Edge）

• Cloudflare Workers / Containers / Workflows：在全球边缘节点运行应用与任务编排，延迟低、弹性强。([Cloudflare Docs][19])

AI/GPU 专用云（训练&推理）

• CoreWeave、Crusoe Cloud 等专注于高性能 GPU、低排队与大规模算力的“AI Cloud”。([CoreWeave][20], [crusoe.ai][21])

怎么选（3 步快选）

1. 先看合规与地域：是否需要主权/本地化（如欧盟本地、国区合规）？需要就优先考虑本地厂商或具备主权云产品的供应商（如 OVHcloud、OCI EU Sovereign Cloud 等）。([oracle.com][5], [OVHcloud][11])
2. 再看能力与生态：通用业务、全托管服务与全球覆盖优先选三大（AWS/Azure/GCP）；数据库/ERP 及低出口带宽费可看 OCI；混合主机与行业合规模块可看 IBM/华为云等。([Amazon Web Services, Inc.][1], [微软 Azure][2], [Google Cloud][3], [oracle.com][5], [IBM][6])
3. 最后看成本/性能：中小团队与简单工作负载可选 DigitalOcean/Vultr 等；边缘实时类应用看 Cloudflare；大模型训练/推理密集则看 CoreWeave/Crusoe 等 AI 专用云。([docs.digitalocean.com][15], [irqm.com][18], [Cloudflare Docs][19], [CoreWeave][20], [crusoe.ai][21])
