Azure vs AWS: Choosing the Right Cloud for Your Data
Both Azure and AWS are world-class platforms — the right choice depends on your data stack and integration needs.
Azure and AWS between them power the majority of the world's cloud infrastructure — and both are genuinely excellent platforms. The question isn't which one is better in the abstract; it's which one is better for your specific situation, team, and existing technology stack.
AWS: The default choice for startups and tech companies
Amazon Web Services has the broadest service catalogue, the largest ecosystem of third-party tools and integrations, and the deepest pool of engineering talent. If you're building a greenfield cloud infrastructure and your team doesn't have strong Microsoft ties, AWS is often the natural starting point.
Azure: The enterprise and Microsoft-stack choice
Microsoft Azure is the dominant choice for organisations already invested in the Microsoft ecosystem — Microsoft 365, Active Directory, SQL Server, Dynamics 365. Azure's native integration with these tools is unmatched, and its hybrid cloud capabilities (Azure Arc, ExpressRoute) are best-in-class for organisations with on-premise infrastructure.
For data engineering specifically
Azure shines with Azure Data Factory (ETL orchestration), Azure Synapse Analytics (unified analytics), and seamless Power BI integration. AWS excels with Redshift (data warehousing), Glue (managed ETL), and S3 (cost-effective data lake storage). Both platforms can handle any data engineering workload at any scale.
Cost considerations
AWS and Azure have comparable pricing at most scales, but the devil is in the details. Egress costs, reserved instance pricing, and support tiers vary. In our experience, a proper architecture review can reduce cloud spend by 30–40% compared to a naive deployment on either platform.
