Choosing a cloud platform is one of the most lasting technology decisions a business makes. Amazon Web Services (AWS), Microsoft Azure and Google Cloud dominate the market, and IBM Cloud serves a specific niche of regulated and hybrid workloads. Each is excellent at some things and weaker at others. This guide compares AWS vs Azure vs Google Cloud vs IBM Cloud in 2026: market position, strengths, pricing approach, and which fits which kind of business.
Market Position in 2026
According to Synergy Research Group’s figures for Q2 2026, AWS held about 28% of the cloud infrastructure market, Microsoft Azure about 20% and Google Cloud about 15%, its highest share on record. Together the three account for well over half of global cloud infrastructure spending, which is still growing fast, driven largely by AI workloads. IBM Cloud is much smaller in overall share but remains significant in banking, government and other regulated industries.
Amazon Web Services (AWS)
Best for: the broadest range of services, mature tooling and the largest ecosystem.
- Strengths: the widest catalogue of services (compute, storage, databases, analytics, AI and IoT), the most regions and availability zones, very mature operations tooling, and the largest pool of engineers, partners and documentation.
- AI: Amazon Bedrock for access to multiple foundation models, SageMaker for building and training models, and its own Trainium and Inferentia chips.
- Watch out for: complexity and cost management. Hundreds of services and pricing options make it easy to overspend without good governance.
Microsoft Azure
Best for: organisations built on Microsoft: Windows Server, SQL Server, Active Directory (Entra ID), Microsoft 365 and .NET.
- Strengths: seamless identity integration with Entra ID, licence benefits for existing Windows Server and SQL Server customers (Azure Hybrid Benefit), strong hybrid options with Azure Arc and Azure Local, and broad enterprise and government compliance.
- AI: Azure OpenAI Service and Azure AI Foundry, closely tied to Microsoft’s partnership with OpenAI and to Copilot across Microsoft products.
- Watch out for: a portal and service naming that change often, and support quality that varies by plan.

Google Cloud
Best for: data analytics, AI and machine learning, Kubernetes and cloud-native development.
- Strengths: BigQuery for large-scale analytics, Google Kubernetes Engine (Google created Kubernetes), a fast global network, simpler pricing with automatic sustained-use discounts, and strong developer tooling.
- AI: Vertex AI and Gemini models, plus Google’s own TPU chips for training and inference.
- Watch out for: a smaller enterprise partner ecosystem than AWS or Azure in some regions, and fewer niche services.
IBM Cloud
Best for: regulated industries, hybrid cloud built on Red Hat OpenShift, and organisations running IBM mainframes or IBM software.
- Strengths: deep integration with Red Hat OpenShift for consistent hybrid and multi-cloud Kubernetes, financial-services-focused compliance controls, bare-metal servers and support for IBM Power and z systems. IBM also owns HashiCorp (Terraform and Vault), completed in 2025.
- AI: watsonx for enterprise AI with a focus on governance.
- Watch out for: a much smaller service catalogue and community than the big three. It is rarely the right choice for general-purpose workloads.

Head-to-Head Summary
- Breadth of services: AWS leads, Azure close behind, then Google Cloud and IBM Cloud.
- Microsoft workloads: Azure is the natural fit.
- Analytics, AI/ML and Kubernetes: Google Cloud is very strong, and AWS and Azure are competitive.
- Hybrid cloud: Azure (Arc, Azure Local) and IBM (OpenShift) stand out, and AWS offers Outposts.
- Regulated industries: all four have strong compliance programmes. IBM and Azure are often preferred in finance and government.
- Talent availability: AWS has the largest pool of skilled engineers, followed by Azure.
Pricing: What Actually Drives Your Bill
List prices for comparable virtual machines and storage are broadly similar across the big three. Real costs depend on:
- Commitment discounts: Savings Plans and Reserved Instances (AWS), reservations and savings plans (Azure), committed and sustained-use discounts (Google).
- Existing licences: Azure Hybrid Benefit can greatly reduce Windows and SQL Server costs.
- Data egress: moving data out of a cloud or between regions can be expensive. Design for it.
- Right-sizing and clean-up: idle and oversized resources are the biggest source of waste.
Our guide to cloud cost optimisation covers this in depth.
How to Choose
- Start from your workloads and skills, not from marketing. What do you run today, and what does your team know?
- Check regional availability and data residency requirements for your customers.
- Run a proof of concept with a real workload and measure performance and cost.
- Consider support and partners available to you locally.
- Avoid unnecessary lock-in: containers, Kubernetes and infrastructure as code keep options open.
Is Multi-Cloud Worth It?
Many organisations use more than one cloud, often by accident (one team on AWS, another on Microsoft 365 and Azure). Deliberate multi-cloud can reduce dependency on one vendor and let you use each provider’s strengths, but it adds complexity, skills requirements and networking costs. For most small and mid-size businesses, one primary cloud with portable tooling is the better starting point.
Frequently Asked Questions
Which cloud is the cheapest?
None is consistently cheapest. Costs depend on your workloads, discounts and existing licences. Azure is often cheaper for Microsoft-heavy environments, and Google Cloud’s automatic discounts help steady workloads.
Which cloud is best for AI?
All three major clouds offer strong AI platforms. Google Cloud (Vertex AI, Gemini, TPUs) and Azure (Azure OpenAI) are popular for generative AI, and AWS Bedrock offers a broad choice of models.
Is IBM Cloud still relevant?
Yes, for specific cases: regulated financial services, hybrid OpenShift deployments and organisations invested in IBM systems. For general workloads, most businesses choose AWS, Azure or Google Cloud.
Can we move between clouds later?
Yes, but it takes planning. Using containers, Kubernetes, open-source databases and infrastructure as code makes future moves much easier.
