Cloud Exit Strategy: How to Migrate from AWS to Bare Metal in 2025

A practical, phased approach to cloud repatriation — saving 40-60% on infrastructure costs while maintaining performance and reliability for UK businesses.

📅 July 19, 2026 • 📖 13 min read • By Hostingowy Engineering

In 2024, 37% of UK businesses reported cloud costs exceeding budget by more than 25%. The era of "lift and shift" to public cloud is giving way to a more nuanced approach: cloud repatriation — moving workloads from hyperscale clouds back to dedicated infrastructure.

This guide presents a complete cloud exit strategy for UK businesses considering migration from AWS, GCP, or Azure to bare metal hosting. We'll cover cost analysis, migration planning, execution phases, and common pitfalls to avoid.

Why UK Businesses Are Leaving the Public Cloud

The cloud repatriation trend is accelerating. Here's why UK businesses are making the move:

Factor	Cloud (AWS/Azure/GCP)	Bare Metal (Hostingowy)
Monthly cost (32 vCPU, 64GB RAM, 1TB NVMe)	$800-1,200	$200-400
Data egress fees	$0.05-0.09/GB	$0 (unmetered)
UK data sovereignty	Varies by region	European data centres (Poland)
Performance consistency	Shared (noisy neighbour)	Dedicated resources
Support quality	Enterprise tier: $$$$	UK engineers, included
Vendor lock-in risk	High (proprietary services)	Low (open standards)

Phase 1: Cost Analysis & Workload Assessment (Week 1-2)

Before migrating, understand exactly what you're spending and where. Use our free cloud cost assessment tool to compare your current cloud spend against bare metal alternatives.

Audit Your Current Cloud Spend

Export AWS Cost and Usage Report (CUR) or Azure Cost Management data
Identify the top 10% of resources by cost — these are your primary candidates
Calculate effective hourly costs including reserved instance amortisation
Include data transfer costs (NAT gateway, egress, inter-AZ traffic)
Add managed service premiums (RDS, ElastiCache, Load Balancers)

Classify Workloads by Migration Suitability

Tier 1 — Immediate repatriation: Stateless web servers, batch processing, CI/CD runners
Tier 2 — Short-term migration: Stateful applications with clear data sync strategies
Tier 3 — Longer-term: Heavy database workloads requiring careful replication
Stay-in-cloud: Truly elastic workloads (auto-scaling with <5 min peaks), serverless functions

Phase 2: Migration Planning (Week 3-4)

Network Topology Design

Design your bare metal network with redundancy in mind:

┌─────────────┐     ┌─────────────┐
│  Primary DC  │◄───►│  DR DC      │
│  (London)    │     │  (Manchester)│
├─────────────┤     ├─────────────┤
│ Web Tier    │     │ Web Tier    │
│ App Tier    │     │ App Tier    │
│ Database    │     │ Database    │
└─────────────┘     └─────────────┘
       │                    │
       └────────┬───────────┘
                │
         ┌──────┴──────┐
         │  DNS (Geo)  │
         │  CDN (Cloudflare)│
         └─────────────┘

Data Migration Strategy

For databases, use replication rather than dump-and-restore for zero-downtime:

# PostgreSQL replication setup
# On existing cloud database:
SELECT pg_create_physical_replication_slot('bare_metal_replica');

# On new bare metal server:
pg_basebackup -h cloud-db.example.com -D /var/lib/postgresql/16/main \
  --slot=bare_metal_replica --progress --verbose

# Configure streaming replication
# Add to postgresql.conf on bare metal:
primary_conninfo = 'host=cloud-db.example.com port=5432 user=replicator password=****'

Phase 3: Migration Execution (Week 5-8)

Week 5: Network & Security Layer

Configure VPN or Direct Connect between cloud VPC and bare metal network
Set up firewalls, WAF, and DDoS protection
Deploy monitoring (see our Grafana setup guide)
Configure DNS with low TTL for rapid cutover

Week 6-7: Workload Migration (Staggered)

Move Tier 1 workloads first (stateless, easy to roll back)
Run in hybrid mode for 48 hours to validate performance
Move Tier 2 workloads with data replication
Final cutover of Tier 3 databases

Week 8: Validation & Decommission

Run full integration tests from bare metal infrastructure
Monitor performance, latency, and error rates for 72 hours
Decommission cloud resources systematically
Cancel cloud subscriptions — avoid surprise charges!

Real-World Cost Savings Example

        Case Study: UK SaaS Company (50 employees)

        Monthly AWS bill: $24,500

        Equivalent Hostingowy dedicated infrastructure: $8,200

        Annual savings: $195,600 (66% reduction)

        Migration timeline: 6 weeks

        Performance improvement: 35% lower latency for UK users

        Support response time: 5 minutes (vs 2-4 hours with AWS support)

Common Cloud Exit Pitfalls

Pitfall 1: Ignoring Data Egress Costs

AWS charges $0.09/GB for data transfer out. Moving 10TB before cutover would cost $900. Plan your data migration to minimise egress — use Direct Connect or ship physical drives.

Pitfall 2: Keeping Unused Resources Running

During migration, it's common to keep old cloud resources "just in case." Set a decommission date and stick to it. Every week of overlap costs 15-25% of your monthly cloud bill.

Pitfall 3: Underestimating Network Engineering

Hybrid cloud setups require careful network engineering. Invest in proper VPN or dedicated connectivity between your bare metal and any remaining cloud resources during transition.

Conclusion

Cloud repatriation is not about rejecting cloud technology — it's about making the right economic choice for your workload. For UK businesses with predictable workloads, bare metal hosting offers 40-60% cost savings, better performance, and simpler GDPR compliance through guaranteed UK data residency.
