Hetzner vs Azure: Cost, Data Sovereignty Compared
Hetzner is a strong option for lean IaaS, dedicated servers, and self-managed open-source stacks. Azure is usually stronger for organisations built around Microsoft Entra ID, Microsoft 365, Windows licensing, hybrid management, AKS, and a broad managed-service catalogue. Select by workload and operating model; neither a European provider nor an EU Azure region automatically guarantees data sovereignty.
Integration can outweigh the compute invoice
Azure can centralize identity, policy, endpoint management, private connectivity, security monitoring, Windows and SQL Server licensing, and application hosting. If those controls are already deployed, reproducing them on Hetzner may create more systems and incident paths. Conversely, a Linux service using standard virtual machines, PostgreSQL, object storage, and Kubernetes may gain little from Azure-specific integration.
For containers, compare self-managed Kubernetes on Hetzner with Azure Kubernetes Service. AKS manages important control-plane functions but still leaves workload security, node strategy, upgrades, networking choices, backups, and observability to the customer. Write a responsibility matrix rather than calling either design simply “managed” or “self-hosted.”
Use total cost and an application benchmark
Build a date-stamped model from the current Hetzner catalogue and Azure virtual-machine pricing. Include reservations or savings plans, licence benefits, disks and performance tiers, snapshots, load balancers, public IP, NAT, inter-zone traffic, egress, DNS, monitoring and log ingestion, Defender, backups, support, currency, and tax. Add staff time for every managed Azure component that would become a customer-operated service on Hetzner.
Benchmark on the exact instance family and location with production-like data. Measure tail latency, sustained CPU, storage IOPS and latency, network throughput, provisioning, failover, and restore. A vCPU count does not normalize processor generation, sharing, throttling, or storage. Avoid static percentage savings unless the assumptions, date, and reproducible test are published.
Data location is only one control
Hetzner Cloud currently lists German, Finnish, US, and Singapore locations in its official documentation. Azure has many regions and publishes service availability per region. For either provider, map primary data, replicas, snapshots, logs, support artifacts, identity, telemetry, and disaster recovery. Confirm the contracted locations rather than infer them from the VM region.
Review controllers and processors, legal entities, subprocessors, support access, transfer mechanisms, encryption and key custody, retention, audit evidence, and incident notice. Microsoft's GDPR documentation describes Azure and Microsoft compliance resources, but the customer remains responsible for its use. Choose Hetzner when simplicity and portability win; choose Azure when Microsoft integration or managed services deliver measured value. In both cases, test account recovery, location failure, backup restore, and provider exit.
