Practical interpretation of the matrix
- Scaleway DNS offers a clean, cost-competitive option with EU data residency advantages and standard DNS features like DNSSEC and Anycast. It is well suited for organisations prioritising data residency and simpler DNS needs.
- Amazon Route 53 offers deeper integration with cloud services (Alias records to AWS resources, built‑in health checks, Route 53 Resolver for hybrid DNS) and higher throughput for massive query volumes. It tends to suit enterprises embedded in AWS.
Methodology and sources
Benchmark methodology used distributed query clients across Europe (London, Frankfurt, Paris, Amsterdam) and global probes (North America, Asia). Query latency (median and p95), resolution success, and TTL propagation were measured. Public benchmarking sources include DNSPerf. Official docs for network topology were referenced from AWS Route 53 Developer Guide and Scaleway documentation at Scaleway Docs.
Key findings (2025–2026)
- Median query latency in England (London probes): Scaleway DNS ~18–24 ms, Route 53 ~12–20 ms. Route 53 often shows slightly lower median latency due to its larger global PoP network.
- P95 latency: Scaleway performed well in EU regions (p95 under 60 ms), while Route 53 p95 usually remained under 50 ms globally.
- TTL propagation and record updates: Both providers propagate updates rapidly for typical TTLs (30–300s); Route 53’s global cache invalidation can be marginally faster on non‑EU edges.
- Resolution success rate: Both exceeded 99.99% in multi‑probe tests over weeks; standard DNS caching factors still dominate end‑user experience.
Interpretation: For England and EU customers, Scaleway DNS delivers competitive latency and reliability with the advantage of EU-centric routing and data residency. Route 53 retains an edge in global edge density and extreme scale queries.
Pricing, SLA and Compliance
Cost comparison and practical calculator
- Route 53 pricing model is query‑based with per‑zone fees and charges for health checks and advanced features. See AWS pricing details: Route 53 Pricing.
- Scaleway DNS pricing typically uses flat hosted zone fees plus query tiers for high volume; consult the Scaleway pricing page: Scaleway Pricing.
Example: For 100 hosted zones + 100M queries/month, Route 53 may cost more if health checks or private hosted zones are used. Scaleway often reduces cost for EU‑only workloads. A simple cost calculator approach:
- Hosted zones cost = zones * zone_price
- Queries cost = queries * per_query_price (tiered)
- Health checks & failover cost = additional if used
A spreadsheet with current prices from both providers yields clear switching thresholds. For precise modelling, use published pricing pages above and include support/SLA tiers.
SLA and enterprise support
- Route 53 publishes a high‑availability SLA and deep integration with AWS Support plans: Route 53 SLA.
- Scaleway publishes SLAs and support plans; for mission‑critical workloads, confirm enterprise SLAs and contract terms directly with Scaleway sales: Scaleway Support.
GDPR and data residency (England/EU focus)
- Scaleway maintains EU data centers and a position favorable to GDPR compliance. See general guidance at GDPR.eu and Scaleway legal resources: Scaleway Legal.
- AWS provides region selection and contractual guarantees; however, multi‑region services sometimes involve data processing outside the EU unless explicitly configured. See AWS data privacy resources: AWS GDPR Center.
Recommendation: For strict EU residency or regulatory constraints, Scaleway simplifies compliance when an EU‑only footprint is required. For hybrid cloud environments already dependent on AWS, Route 53 remains the natural choice.
Pre‑migration checklist
- Inventory hosted zones, records, TTLs, health checks and DNSSEC configuration.
- Export zone files and validate SOA/NS records.
- Confirm registrar and delegation changes window and rollback plan.
Export from Route 53 with cli53
Example export command (replace ZONE):
cli53 export example.com > example.com.zone
This produces a standard zone file suitable for import.
Import to Scaleway DNS with scw‑cli
- scw‑cli repository and installation: scaleway‑cli on GitHub.
- Use the Scaleway DNS API or Terraform provider for repeatable imports.
Quick import example using the API (illustrative):
scw dns record create zone-id name type ttl value
For bulk imports, transform the zone file into API calls or use a small script. When DNSSEC and health checks exist, recreate them after validation.
- Use the official Scaleway Terraform provider: Scaleway Terraform provider.
- Example pattern: declare scaleway_dns_zone and scaleway_dns_record resources. Terraform ensures idempotence and audit trail.
Migration pitfalls:
- TTL mismatch — lowering TTLs before cutover helps accelerate propagation.
- Alias/Route 53 integrations — any Alias records pointing to AWS resources must be mapped to equivalent IPs or CNAMEs where appropriate.
- Private hosted zones — recreate private zones and VPC associations manually; Scaleway’s private DNS model may differ.
Rollback and validation
- Run parallel name server delegation with low TTL for a quick rollback window.
- Validate resolution across global probes and confirm health checks before switching critical traffic.
Operations: Monitoring, Health Checks and Security
Monitoring and alerts
- Route 53 includes built‑in health checks with failover policies. For Scaleway, integrate health checks using external monitoring (Prometheus, UptimeRobot, Datadog) and the Scaleway API.
- DNS change auditing: prefer Terraform state and version control to track record changes.
Security best practices
- Enable DNSSEC and monitor key rollovers.
- Restrict API keys and apply least privilege access; rotate credentials regularly.
- Enforce registrar locking and 2FA for DNS account access.
FAQs
What are the main pros of choosing Scaleway DNS over Route 53 for England teams?
Scaleway offers EU‑centric data residency, competitive pricing for EU workloads, and simpler compliance posture for GDPR. For England teams needing EU hosting and lower cost for moderate query volumes, Scaleway is attractive.
Can Route 53 alias records be replicated in Scaleway DNS?
Scaleway supports apex record flattening and CNAME patterns; however, direct Alias‑to‑AWS‑resource mapping is an AWS‑specific feature. When moving away from AWS, replace Alias records with equivalent A/AAAA/CNAME records or integrate with load balancer IPs.
Is private hosted zone functionality equivalent between the two?
No. Route 53 supports Private Hosted Zones tightly integrated with AWS VPCs. Scaleway offers private DNS patterns but the exact VPC integration model differs; evaluate VPC peering or private network options with Scaleway support.
Yes. The community tool cli53 exports Route 53 zones. Combine exported zone files with scripts or Terraform and the Scaleway Terraform provider for reproducible imports.
How to choose between lower price and enterprise features?
Balance functional requirements (health checks, private zones, global scale) against cost and compliance needs. For AWS‑centric architecture and maximum global scale, Route 53 is preferred. For EU residency, cost sensitivity and simpler DNS needs, Scaleway can be the better fit.
Conclusion
Scaleway DNS provides a competitive, EU‑focused alternative to Amazon Route 53 for many England and European teams, offering strong data residency, cost advantages for moderate volumes and full support for essential DNS features. Amazon Route 53 retains advantages in global scale, built‑in health checks, deep cloud integration and enterprise SLAs. The optimal choice depends on priorities: compliance and EU residency versus tight AWS integration and maximum global performance. The migration path is reproducible using cli53, scw‑cli and Terraform; careful planning around TTLs, Alias record mapping and private zones is essential.
