Scaleway vs Microsoft Azure: immediate clarity matters when choosing a cloud provider for European workloads. The comparison below focuses on measurable differences in performance, real-world cost (including egress), compliance and migration effort. The goal is to equip decision-makers with reproducible benchmarks, TCO scenarios for 1–3 years, and an actionable migration path that reduces risk and avoids hidden costs.
Executive summary: who benefits from Scaleway vs Microsoft Azure
Scaleway positions as a European-first cloud with straightforward pricing, local data centers in France and Poland (and edge locations), and attractive options for startups and EU-sensitive workloads. Microsoft Azure offers global scale, a broader managed-service ecosystem (AKS, Azure SQL, Blob Storage), enterprise-grade compliance and a mature marketplace.
- Scaleway is often better for cost-sensitive VPS/VM workloads, low-latency EU edge needs and predictable egress patterns.
- Azure is stronger for enterprises requiring broad PaaS coverage, global redundancy, advanced identity and analytics services.
Decision factors: latency to user base, TCO including egress, managed service requirements (Kubernetes, DBaaS), and compliance needs such as GDPR or ISO certifications.
Benchmark methodology (2025–2026 reproducible)
- Test types: CPU, single-thread and multi-thread; disk I/O (random 4K and sequential 1M); network throughput (TCP), and regional latency (ICMP/TCP ping plus application-level RTT).
- Regions and windows: EU-West (France, Poland), Azure West Europe (Netherlands), Azure North Europe (Ireland). Tests run during heavy, median and off-peak hours across 7 consecutive days to capture variance. Tools: sysbench for CPU, fio for I/O, iperf3 for network and httperf for GET/POST RTT.
- Instance parity: match vCPU and RAM, use NVMe-backed instances where available. Public images used to minimize variance.
Key benchmark results (summary, 2025–2026)
- CPU: Azure and Scaleway show near-parity on single-core synthetic loads; Azure shows better sustained turbo performance on high-end VM families (Dv5/Esv5) due to newer Intel/AMD variants.
- Disk I/O: Scaleway's block storage with local NVMe performed better on small random IOPS in EU regions for standard instances; Azure Premium SSDs outperform at higher IOPS tiers but at greater cost.
- Network: Azure produced higher throughput for inter-region transfers and cross-cloud peering, while Scaleway offered lower intra-EU latency in adjacent data centers (notably France–Poland tests).

Cost and TCO analysis: pricing, egress and scenarios
Pricing model differences (2025–2026 updates)
- Azure: granular pricing across VM families, managed services, storage tiers and complex discounts (reserved instances, spot, Azure Hybrid Benefit). Billing can be optimized but requires active management.
- Scaleway: simpler price tiers for Instances (DEV1, GP1, etc.), transparent object and block storage pricing, and predictable monthly bills. Less granular discounts but lower base rates for many entry-level workloads.
Egress and network costs
Egress is a common hidden cost. Example: 1 TB/month egress to public internet in 2026:
- Azure West Europe: variable, often higher for cross-region and inter-cloud egress; enterprise agreements can reduce rates.
- Scaleway: generally lower public egress in EU zones with fixed monthly allowances on some plans.

Managed services, ecosystem and developer experience
Kubernetes and container services
- Azure Kubernetes Service (AKS): deep integrations with Azure Active Directory, monitoring via Azure Monitor and rich marketplace integrations. Strong for enterprises standardizing on Microsoft stack.
- Scaleway Kapsule: lightweight managed Kubernetes, simple billing and EU-focused locality. Easier to start, less feature-rich for large-scale multi-tenant enterprise setups.
Managed databases and storage
- Azure: Azure SQL, Cosmos DB, Blob Storage — broad choices for relational, NoSQL and object storage with global replication.
- Scaleway: Managed Databases (Postgres, MySQL) and Object Storage (compatible with S3 API). Best for straightforward workloads and EU-resident data.
Marketplace and integrations
Azure marketplace offers thousands of partner services and enterprise ISVs. Scaleway's marketplace is smaller but covers common OSS stacks and turnkey offerings.
Compliance, security and regional presence
Certifications and EU data residency
- Azure holds numerous standards (ISO, SOC, PCI, many national accreditations) and publishes compliance materials: Azure compliance.
- Scaleway publishes security and compliance documentation with EU-focused controls and data residency options: Scaleway Docs.
Regulatory reference: GDPR text and official regulation: EU GDPR (Regulation 2016/679).
Security features
Both providers offer encryption at rest, key management options and network security groups. Azure provides a mature identity platform (Azure AD) and security center integrations; Scaleway provides standard cloud protections and European-focused support for data processing agreements.
Migration guide: practical steps for minimal downtime
Step 1: Inventory and dependency mapping
- Catalog VMs, containers, storage, DNS entries, and service dependencies.
- Use discovery tools (manual or automated) and map data egress and compliance constraints.
Step 2: Proof-of-concept and benchmark parity
- Deploy representative workloads on target provider and run the reproducible benchmarks described above.
- Validate latency, IOPS and cost under expected load.
Step 3: Data migration strategy
- For block storage: snapshot and replicate during low-traffic windows; prefer incremental replication tools.
- For object storage: use S3-compatible tooling (rclone, s3cmd) or vendor transfer services.
Step 4: Cutover and validation
- Route a percentage of traffic to the new environment (canary), validate logs and monitoring, and then perform full cutover.
- Maintain rollback plan and validate backups.
Sources for migration patterns: vendor migration guides such as Azure Migration and Scaleway Docs.
Decision matrix: when to choose which
- Choose Scaleway when: EU data residency, lower baseline costs, simple managed Kubernetes, or startup credits matter.
- Choose Azure when: global footprint, advanced PaaS and analytics services, enterprise identity and governance are required.
FAQ
What are the main cost differences between Scaleway and Azure?
Costs differ by instance family, storage tier and egress. Scaleway typically offers lower entry-level VM prices and simpler egress for EU zones. Azure often becomes cost-effective at scale with committed-use discounts or existing Microsoft licensing benefits.
Is Scaleway compliant with GDPR for EU workloads?
Yes. Scaleway provides EU data residency options and documentation to support GDPR compliance; consult legal teams and vendor DPA terms for specific processing activities: Scaleway Docs.
Does Azure offer better SLA guarantees?
Azure publishes enterprise SLAs across services. SLA levels vary by service and configuration; review Azure SLA pages for service-level details: Azure SLA.
How large is the marketplace and third-party ecosystem?
Azure's marketplace is substantially larger with established ISVs, whereas Scaleway's marketplace is smaller but growing and focused on common open-source stacks.
Which provider has lower latency inside Europe?
Latency depends on exact region and topology. Scaleway can offer lower intra-France/Poland latency for localized workloads; Azure provides low-latency options across multiple EU regions and peering hubs.
Are there startup credits or programs available?
How to estimate egress costs accurately?
Measure expected outbound traffic by month, identify destinations (internet vs cross-region), and run sample transfers using vendor calculators. Always add a buffer for spikes.
What are migration risks and how to mitigate them?
Risks: data transfer costs, service incompatibilities, downtime. Mitigation: test migrations with representative data, use incremental replication, and maintain rollback procedures.
Conclusion
Scaleway and Microsoft Azure serve different needs across the European market. Scaleway excels for straightforward, EU-resident workloads with predictable egress and lower entry costs. Azure excels for enterprises needing global scale, advanced PaaS and a large ecosystem. A reproducible benchmark and a clear TCO model are essential before committing.
