Choosing between AWS and Azure is one of the most consequential technology decisions a Belgian company can make. Both platforms offer mature, enterprise-grade services, but they differ in important ways — from pricing models and regional availability to ecosystem integration and support for European compliance requirements. This guide breaks down the practical considerations that matter most for Belgian organisations.
Regional Availability and Data Residency
For Belgian companies subject to GDPR and NIS2, data residency is a primary concern. Both AWS and Azure operate data centres in the EU:
- AWS has EU regions in Ireland (eu-west-1), Frankfurt (eu-central-1), Paris (eu-west-3), Stockholm (eu-north-1), Milan (eu-south-1), Spain (eu-south-2), and Zurich (eu-central-2). There is no dedicated Belgium region, but Frankfurt and Paris offer low-latency access.
- Azure operates regions in the Netherlands (West Europe), Ireland (North Europe), France, Germany, Sweden, Switzerland, and others. The West Europe region in the Netherlands is geographically closest to Belgium.
Both providers offer contractual guarantees that data stays within the EU when you use EU regions. Azure's EU Data Boundary initiative provides additional controls for organisations with strict data sovereignty requirements.
Enterprise Integration and Ecosystem
One of the most practical differentiators is how well each platform integrates with your existing technology stack:
- Azure has a clear advantage for organisations already invested in Microsoft technologies — Active Directory, Office 365, Teams, Dynamics 365, and .NET development. Azure AD provides seamless single sign-on, and Azure DevOps offers a tightly integrated CI/CD platform.
- AWS tends to be preferred by teams with a Linux-first, open-source-oriented approach. Its ecosystem of managed services is broader, and it has stronger offerings in areas like machine learning (SageMaker), serverless (Lambda), and container orchestration (EKS).
Many Belgian enterprises run Microsoft-centric IT environments, which often makes Azure the path of least resistance for initial cloud adoption. However, this should not be the only factor in your decision.
Pricing and Cost Management
Both platforms use pay-as-you-go pricing, but the details differ:
- AWS generally offers more granular pricing with per-second billing for EC2 and a wide range of instance types. Its Reserved Instances and Savings Plans provide significant discounts for committed usage.
- Azure offers competitive pricing, especially for organisations with existing Microsoft Enterprise Agreements. Azure Hybrid Benefit allows you to apply existing Windows Server and SQL Server licences to cloud workloads, which can significantly reduce costs.
For cost optimisation, both platforms require active management. Consider implementing a FinOps practice regardless of which provider you choose.
Service Maturity and Breadth
AWS has been in the market longer and generally offers a wider range of managed services with more configuration options. Azure has closed the gap substantially and leads in some areas, particularly hybrid cloud (Azure Arc), identity management (Azure AD), and integration with enterprise SaaS.
Key areas where each platform excels:
- Kubernetes: both EKS (AWS) and AKS (Azure) are mature, but AKS is often considered easier to set up and has tighter Azure AD integration. See our managed Kubernetes comparison for more detail.
- Serverless: AWS Lambda has broader language support and a more mature event-driven ecosystem. Azure Functions integrates well with Azure services and supports durable functions for long-running workflows.
- Database: AWS offers a wider range of purpose-built databases (DynamoDB, Aurora, Redshift). Azure provides strong SQL Server compatibility through Azure SQL and Cosmos DB for multi-model workloads.
Support and Local Presence
Both AWS and Azure have sales and support teams active in Belgium and the Benelux region. Azure benefits from Microsoft's long-established enterprise relationships in Belgium, and many Belgian IT professionals are already familiar with Microsoft certifications. AWS has been expanding its European enterprise support network and offers comprehensive training programs.
For organisations that need hands-on support, the availability of certified partners in Belgium is an important consideration. Both ecosystems have active partner networks in the Belgian market.
Making the Decision
There is no universally correct answer. The best choice depends on your specific context:
- If your organisation runs Microsoft-centric IT (Active Directory, Office 365, .NET), Azure offers the smoothest integration path.
- If you need the broadest range of managed services and your team is comfortable with open-source tooling, AWS is likely the better fit.
- If you want to avoid vendor lock-in, consider a multi-cloud strategy — but be realistic about the added complexity.
