Cost scenarios (estimated monthly, England-based usage, 2026 price reference)
| Workload |
Scaleway (estimate) |
AWS (estimate) |
Notes |
| Small web app (t2-equivalent, 2 vCPU, 4 GB RAM, 50 GB SSD, 1 TB egress) |
€22–€35 |
€40–€65 |
Scaleway often shows lower baseline VM costs; egress and managed services change outcome |
| Container cluster (3 nodes, 4 vCPU/8 GB each, managed k8s) |
€120–€180 |
€200–€320 |
Kapsule includes simpler pricing; EKS control plane and node costs typically add overhead |
| Storage-heavy backup (10 TB object storage + 2 TB monthly egress) |
€90–€160 |
€140–€300 |
Scaleway cold and object tiers can be cheaper for EU data; AWS S3 infrequent/Glacier tiers have different retrieval costs |
Notes: These figures are estimates for comparison. Exact totals depend on reserved instances, spot usage, discounts, and committed contracts. For precise numbers, consult both providers' pricing pages and apply workload metrics.
Egress and hidden cost considerations
- Egress costs often drive surprises. AWS has tiered pricing and region-specific rates; Scaleway typically offers generous quotas on some plans but charges per-GB after thresholds. Always model egress for expected patterns.
- Managed databases, backup I/O, and snapshot storage often add 10–40% to compute-only estimates.
Benchmark goals and independent methodology
- Goals: measure raw compute (single-core and multi-core), disk I/O, network throughput, and cold-starts for serverless functions.
- Environments: use comparable instance families (vCPU and RAM parity), same OS image (Ubuntu 22.04 LTS), and isolated time windows to avoid noisy neighbours.
- Reproducibility: provide shell scripts and commands to deploy tests. Use multiple runs, median results, and standard deviation reporting.
Reproducible test commands (example)
- Provision instance (Scaleway CLI):
scw instance server create name=bench-1 image=ubuntu_focal type=c2-7
- Provision instance (AWS CLI):
aws ec2 run-instances --image-id ami-0abcdef1234567890 --count 1 --instance-type t3.medium --key-name KEY
- CPU benchmark (sysbench):
sudo apt update && sudo apt install -y sysbench
sysbench cpu --cpu-max-prime=20000 run
sudo apt install -y fio
fio --name=randread --ioengine=libaio --iodepth=16 --rw=randread --bs=4k --direct=1 --size=2G --numjobs=4
- Network throughput (iperf3):
iperf3 -s
iperf3 -c SERVER_IP -t 60 -P 8
Results should be averaged over three runs and collected with timestamps and instance metadata.
Example findings (publicly reported patterns 2025–2026)
Independent analysts such as CloudSpectator and community benchmarks often show: AWS generally leads in raw network performance and specialized instance types, while smaller cloud operators like Scaleway provide competitive CPU/disk performance for mainstream instance classes at a lower list price.
Managed services: Kubernetes, serverless, databases
Kubernetes: EKS vs Kapsule
- AWS EKS: Highly integrated with AWS IAM, ALB, CloudWatch, and autoscaling. Additional cost overhead from control plane and managed node groups unless using AWS Fargate.
- Scaleway Kapsule: Simpler pricing model with a managed control plane and options for single-tenant nodes. Good for teams wanting straightforward k8s management with EU-focused data residency.

Serverless and functions
- AWS Lambda: Mature, broad language/runtime support, deep ecosystem integrations and provisioned concurrency for predictable latency. Pricing model includes per-invocation and GB-second billing.
- Scaleway Functions: Compatible with common runtimes and typically competitive on price for EU workloads; fewer integrations but simpler cost profile.
Managed databases and storage
- AWS: RDS, Aurora, DynamoDB — a wide spectrum from fully managed relational to serverless NoSQL with strong SLA and global availability.
- Scaleway: Managed databases support common engines (PostgreSQL, MySQL, Redis) with simpler pricing; fewer advanced features than Aurora.
Compliance, data sovereignty and certifications (England/EU focus)
- GDPR: Both providers publish compliance resources. AWS maintains a GDPR Center and offers data processing addendums; Scaleway emphasises EU-focused data residency and compliance information.
References: AWS GDPR Center, Scaleway compliance.
- Certifications: AWS has an extensive catalog (ISO 27001, SOC, PCI DSS). Scaleway lists ISO and other regionally relevant certifications for select services. For regulated workloads, validate specific service-level certifications and regional availability before migration.
Latency, regions and network topology
- AWS: AWS UK & Europe regions (multiple AZs) provide low-latency endpoints across England and continental EU. Global edge network reduces latency for worldwide users.
- Scaleway: EU-focused regions (France, Netherlands, Poland) provide competitive intra-EU latency and can reduce cross-border data transfer in EU-first architectures.
Recommendation: measure p95 latency from key user locations using simple curl or httping tests to target endpoints before committing.
Migration checklist and practical commands (step-by-step)
Pre-migration: assessment and planning
- Inventory applications, dependencies, and data flows.
- Classify data by sensitivity and residency requirements.
- Estimate egress volumes and run cost modelling for both providers.
Lift-and-shift checklist (example steps)
- Export VM images or container images.
- Snapshot databases and replicate with logical or physical replication.
- Test restores and validate data integrity.
- Plan DNS TTL lowering and cutover window.
Example database migration commands (Postgres logical replication)
pg_dump -h source-host -U user -F c -b -v -f appdb.dump appdb
pg_restore -h target-host -U user -d appdb -v appdb.dump
Container migration (Docker to Kapsule/EKS)
- Build and push images to a registry (example uses Docker Hub or a private registry):
docker build -t registry.example.com/org/app:1.0 .
docker push registry.example.com/org/app:1.0
- Deploy manifest to target cluster using kubectl. For EKS, configure AWS IAM Authenticator; for Kapsule, use scaleway IAM credentials as needed.
Cutover and rollback plan
- Use weighted DNS or blue/green deployments to reduce downtime.
- Keep a tested rollback snapshot and clear rollback steps defined in runbook.
Case studies and quantified outcomes (anonymised patterns)
- EU SaaS startup (containerised): switching core services to Scaleway reduced monthly cloud bill by ~28% vs AWS on comparable on-demand usage, with similar latency for EU users. Savings came mainly from lower baseline VM pricing and simpler k8s pricing.
- Mid-market analytics firm: remaining on AWS for global ML workloads due to specialised GPU instance access and integrated ML tooling; costs were higher but time-to-insight and feature velocity increased.
Decision matrix: quick checklist to choose
- Choose Scaleway if: EU data residency, predictable costs, simpler managed k8s, and lower list pricing matter.
- Choose AWS if: broad global reach, specialised managed services, high availability across many regions, and enterprise-grade compliance features are required.
FAQs
How do egress costs compare between Scaleway and AWS?
Egress pricing varies by region and volume. AWS uses tiered per-GB pricing depending on region and transfer pattern. Scaleway offers competitive per-GB rates for EU regions and sometimes includes free egress quotas on specific plans. Model expected monthly egress precisely and compare using both providers' pricing pages: Scaleway pricing, AWS pricing.
Is migration from AWS to Scaleway straightforward for Kubernetes workloads?
Migrating k8s workloads is feasible but requires attention to cloud-native integrations (load balancers, IAM, storage classes). Export manifests, replace cloud-specific resources with provider-agnostic equivalents, and validate persistent volumes and ingress controllers.
Which provider has better support for EU data residency and GDPR?
Both publish GDPR resources. Scaleway emphasises EU-centric infrastructure; AWS provides extensive compliance tooling and contractual terms suitable for large enterprises. Evaluate the specific service compliance matrix for the workload.
Are managed databases on Scaleway mature enough for production?
Scaleway managed databases support common engines and are suitable for many production workloads. For highly specialised features (Aurora-like scaling or multi-region global databases), AWS offers more advanced options.
Cold-starts depend on runtime and configuration. AWS Lambda optimisations, provisioned concurrency and large scale make it strong for low-latency serverless, while Scaleway Functions can be cost-effective for predictable EU loads.
How to estimate real TCO between providers?
Estimate monthly compute, storage, egress, managed service fees, backup storage, and operational overhead. Run a small pilot for one month in both environments to capture real metrics.
Use standard database replication tools (pg_dump/pg_restore, logical replication for Postgres, and native migration services where available). No vendor lock-in migration tool is strictly required, but ensure network and security policies are configured.
What steps reduce migration downtime?
Use replication or CDC (change-data-capture), lower DNS TTLs before cutover, and implement blue/green deployments or feature flags for rapid rollback.
Conclusion
Choosing between Scaleway and AWS depends on priorities: cost predictability and EU data residency versus global reach and deep managed services. For many England-based organisations with EU-focused users, Scaleway offers a compelling cost-performance balance. For enterprises needing the broadest service ecosystem and specialised compute, AWS remains the default choice. The recommended approach is to run reproducible benchmarks, model TCO with realistic egress estimates, and pilot a migration using the provided commands and checklist to quantify savings and operational impact.
