AWS vs Azure vs Google Cloud: Which Cloud Platform Is Right for Your Business?

Every major technology decision eventually leads to the cloud question. Whether you are migrating legacy infrastructure, building new applications, or evaluating disaster recovery options, the choice between AWS, Azure, and Google Cloud will shape your architecture, your budget, and your team’s productivity for years.

This comparison is written for IT leaders making practical infrastructure decisions, not developers evaluating serverless frameworks. We focus on the considerations that matter most when you are responsible for keeping a business running.

1. Market Position

AWS (Amazon Web Services) is the market leader with the broadest service portfolio and the most mature ecosystem. It has the largest global infrastructure footprint and the deepest bench of certified engineers in the labor market.

Azure (Microsoft) is the fastest-growing cloud platform and the default choice for organizations already invested in the Microsoft ecosystem (Microsoft 365, Active Directory, Dynamics 365). Azure’s hybrid cloud capabilities are the strongest in the market.

Google Cloud is the smallest of the three but leads in data analytics, machine learning, and Kubernetes. It is the platform of choice for organizations with advanced data and AI workloads.

2. When Microsoft Shops Should Default to Azure

If your organization runs Microsoft 365 and Active Directory, Azure offers integration advantages that AWS and Google Cloud cannot match:

  • Azure Active Directory provides single sign-on and identity management that extends seamlessly from your on-premises AD to cloud resources
  • Microsoft 365 integration means your cloud infrastructure, productivity tools, and identity platform share the same management console and licensing structure
  • Azure Hybrid offerings (Azure Arc, Azure Stack) allow you to run Azure services in your own data center, which is critical for regulated industries with data residency requirements
  • Enterprise Agreements that bundle Microsoft 365, Azure, and Dynamics can provide significant cost advantages

For organizations where Microsoft is already the backbone of operations, choosing a different cloud provider creates unnecessary complexity.

3. When AWS Is the Right Choice

AWS excels in scenarios that require the broadest service selection and the most deployment flexibility:

  • Widest service portfolio with 200+ fully featured services covering compute, storage, databases, AI, IoT, and specialized industry solutions
  • Largest global footprint with the most regions and availability zones, which matters for organizations with strict latency or data sovereignty requirements
  • Most mature marketplace with the largest ecosystem of third-party tools, managed services, and partner integrations
  • Strongest for multi-cloud since AWS services are the most commonly supported by third-party tools and platforms

AWS is the default choice when you do not have a strong reason to choose Azure or Google Cloud. Its breadth means you are unlikely to outgrow it.

4. When Google Cloud Makes Sense

Google Cloud wins in specific scenarios where its technical strengths align with your workloads:

  • Data analytics and BigQuery provide the most cost-effective and performant platform for large-scale data warehousing and analytics
  • Kubernetes and GKE (Google Kubernetes Engine) offer the best managed Kubernetes experience, which makes sense given that Google created Kubernetes
  • AI and machine learning through Vertex AI and TPU infrastructure provide advantages for organizations building custom ML models
  • Multi-cloud strategy with Anthos allows you to manage workloads across Google Cloud, AWS, Azure, and on-premises environments from a single platform

Google Cloud is rarely the right choice as a primary platform for general IT infrastructure, but it is often the right choice for specific workloads that leverage its data and AI strengths.

5. Cost Comparison

Cloud pricing is notoriously complex, and all three providers make it difficult to compare apples to apples. General principles:

  • AWS offers the most pricing options (on-demand, reserved, spot, savings plans) which provides flexibility but requires active cost management. Without governance, AWS bills can grow quickly.
  • Azure pricing is competitive with AWS and offers cost advantages through Enterprise Agreement bundling with Microsoft 365. Azure’s hybrid benefit allows you to apply existing Windows Server and SQL Server licenses to cloud workloads.
  • Google Cloud is typically the most cost-effective for compute workloads due to sustained use discounts that apply automatically (no commitment required) and per-second billing. Its pricing is the most transparent of the three.

Regardless of platform, cloud cost optimization requires ongoing attention. FinOps practices and tools should be part of any cloud strategy from day one.

6. Common Mistakes We See

Choosing based on one workload. Organizations often choose a cloud provider based on their first migration project rather than their long-term architecture. A database migration might favor Azure, but your overall infrastructure strategy might be better served by AWS.

Ignoring the team. The cloud platform your team knows is often more important than which platform has the best features. Training costs, hiring availability, and existing certifications all factor into the total cost of ownership.

Underestimating egress costs. All three providers charge for data leaving their platform. This becomes significant for organizations with large data transfer requirements and can make multi-cloud strategies more expensive than expected.

Skipping the negotiation. All three providers offer significant discounts for committed spend. Organizations that go direct without leveraging competitive bids leave money on the table.

7. The Multi-Cloud Question

Many organizations end up running workloads on more than one cloud platform, either by design or by accident. Our guidance:

  • Intentional multi-cloud makes sense when specific workloads have clear advantages on different platforms (e.g., Azure for Microsoft workloads, Google Cloud for analytics)
  • Accidental multi-cloud happens when different teams choose different platforms without coordination, which leads to duplicated costs, fragmented security, and operational complexity
  • Hybrid cloud (combining cloud with on-premises infrastructure) is often more practical than pure multi-cloud and is best supported by Azure

Making the Right Choice

The right cloud platform depends on your existing technology investments, your team’s skills, your specific workloads, and your budget. There is no universally correct answer, which is why vendor-neutral guidance matters.

We help organizations evaluate cloud platforms based on their actual requirements rather than vendor marketing. Whether you are planning your first cloud migration or optimizing an existing deployment, a structured assessment can save you significant time and money.
