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

AWS and Azure together control 55% of the global cloud market. But choosing between them is not about popularity — it is about your existing technology, compliance requirements, and team expertise.

Compute: EC2 vs Virtual Machines

AWS EC2 offers the widest instance type selection and the most mature spot instance market. Azure Virtual Machines integrate seamlessly with Windows Server and Active Directory. If you are a .NET shop with Microsoft licensing, Azure can be 40-60% cheaper through Hybrid Benefit.

Serverless: Lambda vs Azure Functions

AWS Lambda has better cold start performance and broader language support. Azure Functions excel when you need durable orchestration (Durable Functions) or tight integration with Office 365 and Dynamics. For event-driven microservices, both are excellent choices.

AI & Machine Learning

Amazon SageMaker provides the most flexible ML training and deployment environment. Azure Machine Learning integrates better with Python IDEs and has superior responsible AI tooling. If you are using OpenAI models, Azure OpenAI Service offers enterprise-grade access with private networking.

Compliance & Enterprise Features

Both platforms offer HIPAA BAA, PCI-DSS compliance, and SOC 2 certification. Azure has stronger government cloud offerings (Azure Government, Azure China). AWS has more granular IAM policies and a more mature secrets management service (AWS Secrets Manager).

Our Recommendation

For startups and React/Node.js stacks: AWS. For enterprises with Microsoft ecosystems: Azure. For hybrid cloud: Azure. For the deepest service catalog: AWS. Most of our clients end up using both — AWS for compute and Azure for Office 365 integration.
