What cloud service providers do
Cloud providers make technology available through networked services rather than requiring customers to own and operate every underlying system. The familiar categories describe broad types of offering, though many providers now cross category boundaries and support different deployment models.

- Infrastructure as a service (IaaS): on-demand building blocks such as compute, storage, and networking.
- Platform as a service (PaaS): a platform for developing, deploying, or operating applications.
- Software as a service (SaaS): ready-to-use software accessed online.
Cloud services may run in public or private environments, or across hybrid and multicloud arrangements. The category label alone does not tell you whether a provider has the right services, geographic coverage, controls, or economics for a particular workload. Google Cloud describes the range of cloud service and deployment models.
How the 13 providers differ
This is an editorial selection, not a ranking of like-for-like infrastructure vendors. The distinctions below reflect the source article’s characterization of each company, not independent product testing. Names and portfolios can evolve, so verify current offerings before making a decision.
#1 Best Overall
| Provider | Role in this comparison | What to weigh |
|---|---|---|
| Amazon Web Services (AWS) | Broad hyperscale cloud platform | Consider it when a wide range of infrastructure services is relevant; assess service fit, cost, and the complexity of the options you would actually use. |
| Microsoft Azure | Broad hyperscale platform with hybrid-cloud capabilities | Relevant where integration with existing Microsoft environments or hybrid management matters. Microsoft describes Azure Arc as a way to manage resources across environments; see its Azure Arc overview. |
| Google Cloud Platform (GCP; Google Cloud) | Broad hyperscale cloud platform | Compare its services and deployment options against your application and data needs rather than relying on the platform label. |
| Alibaba Cloud | Cloud provider with an Asia-oriented position | Check the specific regions, services, compliance needs, and support arrangements relevant to your users and data. |
| IBM Cloud | Enterprise and hybrid-cloud emphasis | Assess how its offerings fit existing systems, governance requirements, and the skills available to your team. |
| DigitalOcean | Developer-focused infrastructure with an emphasis on simplicity | Compare the services available for your workload and whether a simpler operating model outweighs any missing capabilities. |
| Salesforce Cloud | CRM and SaaS emphasis | Evaluate it as an application and business-software choice, not as a direct substitute for every IaaS platform. |
| Tencent Cloud | Cloud provider with an Asia-oriented position | Confirm regional coverage, workload fit, and applicable data and regulatory requirements. |
| Oracle Cloud Infrastructure (OCI) | Cloud infrastructure platform | Compare the particular infrastructure and application services needed, plus integration and migration effort. |
| Huawei Cloud | Cloud infrastructure provider with a notable position in Gartner’s 2024 IaaS figures | Check availability, support, security requirements, and regulatory fit for your location and use case. |
| Dell Technologies Cloud | Enterprise and hybrid-cloud emphasis | Consider how a hybrid approach would operate alongside existing infrastructure and who will manage it. |
| Vultr | Developer-focused infrastructure with an emphasis on simplicity | Validate service and region coverage against the needs of your application before choosing. |
| Cloudflare | Network security, delivery, and edge services | Assess the specific network and security needs it serves; it is not interchangeable with a general-purpose cloud infrastructure platform. |
What the market figures show—and what they do not
Gartner reported that worldwide public-cloud IaaS services revenue grew 22.5% in 2024 to $171.8 billion. The five largest providers together accounted for 82.1% of that revenue. These figures concern IaaS public-cloud services only; they do not measure all cloud spending, SaaS subscriptions, or the 13 companies as one comparable market.
| Provider | 2024 IaaS public-cloud revenue | 2024 market share |
|---|---|---|
| Amazon | $64.8 billion | 37.7% |
| Microsoft | $41.1 billion | 23.9% |
| $15.5 billion | 9.0% | |
| Alibaba Group | $12.4 billion | 7.2% |
| Huawei | $7.1 billion | 4.1% |
Gartner attributed the market’s expansion to demand for AI infrastructure and cloud migration and modernization. Its Principal Analyst Hardeep Singh said, “As enterprises continue to seek greater flexibility, improved resilience and optimized performance, there is sustained demand for cloud migration and modernization services.” The figures and statement are from Gartner’s August 6, 2025 release on 2024 market results: Gartner’s market announcement.

Benefits of using a cloud service provider
- Less upfront infrastructure spending: usage-based services can shift some costs from capital purchases to ongoing payments. That does not guarantee a lower total cost.
- Capacity that can change with demand: customers may scale resources up or down instead of buying for peak demand, provided the workload and service are designed to support it.
- Provider-operated infrastructure: the provider operates underlying infrastructure, which can reduce some direct maintenance work. Customers still have responsibilities for their configurations, applications, data, and access controls.
- Geographic reach and resilience options: cloud services can support access from multiple locations and architectures designed for resilience. Outcomes depend on deployment choices, provider availability, and the service-level terms in the contract.
Google Cloud’s overview of cloud service providers describes common service models and the range of deployment approaches. AWS promotes its global infrastructure and partner ecosystem in its global infrastructure overview; those are AWS’s own descriptions, not an independent comparison.

- Migration and integration: moving workloads can require application changes, data transfer, testing, and integration with existing systems.
- Security and governance: provider-operated infrastructure does not remove the customer’s need to configure access, protect data, and meet internal or regulatory requirements.
- Internet and service dependence: users and applications rely on connectivity and on the availability of the services they use.
- Less direct infrastructure control: a managed service can reduce operational work while limiting control over parts of the underlying environment.
- Complexity and cost management: service choices, usage patterns, and configuration affect bills and operational effort.
- Portability and lock-in: the OECD’s 2025 competition report identifies technical, contractual, and financial switching barriers, limited standardization and interoperability, security concerns, and egress fees as factors that can raise switching costs or contribute to customer lock-in. Egress charges are a potential issue, not a universal fee that applies identically to every provider or contract. See the OECD report on competition in cloud computing services.
How to choose a cloud service provider
Start with the workload and the outcome you need, not a provider’s overall reputation or market share. Compare providers against the same requirements and cost assumptions.
Rank #3
- Define the service type. Decide whether you need IaaS building blocks, a PaaS development or deployment environment, SaaS applications, or a combination.
- Check workload fit. Identify required compute, storage, networking, databases, application services, and integrations. Confirm that each candidate offers the capabilities you will actually use.
- Map geography and data needs. Check available regions, latency to users and systems, data residency obligations, and any applicable regulatory constraints.
- Review security and governance. Identify required controls, responsibilities, audit needs, and service-level terms. Clarify which controls you configure and which the provider operates.
- Estimate full cost. Include ongoing resource use and data transfer, not just headline compute prices. Model expected and peak use, and check how billing changes as usage grows.
- Test integration and skills. Account for existing systems, migration work, staff expertise, and the effort to operate the service. Microsoft’s Azure Arc material describes one approach to managing hybrid and multicloud resources; verify whether it fits your architecture rather than assuming a management tool eliminates integration work.
- Plan for support and exit. Compare support and service-level commitments, then determine how you would export data, move workloads, and manage any technical, contractual, or transfer-cost barriers if you switch later.
A provider’s scale or service breadth can matter, but neither guarantees the best fit. The right choice is the one that meets the workload’s technical and regulatory requirements at an acceptable full cost, with a migration and exit path your organization can manage.
