On-Premises Hosting in 2026: Why It's 7x More Expensive Than Cloud
On-premises hosting costs £327-771/month vs cloud at £37-93/month. Only 3 scenarios justify self-hosting. Here's the full breakdown.
On-Premises Hosting in 2026: Why It's 7x More Expensive Than Cloud
"Cloud is expensive - we should host it ourselves."
This is one of the most persistent myths in technology. Our research found on-premises hosting costs 7-10x more than cloud for small to medium businesses. The full cost breakdown tells a very different story than the hardware purchase price suggests.
This guide shows exactly where on-premises costs come from and identifies the only three scenarios where self-hosting makes financial sense.
The on-premises cost myth
When people compare on-premises to cloud, they typically compare:
- Server hardware: £3,000 (one-time)
- Cloud: £93/month = £1,116/year
This makes on-premises look cheaper after 3 years. But this comparison ignores:
- Power and cooling
- Internet connectivity
- Physical security
- Hardware maintenance
- Software licensing
- Backup infrastructure
- The elephant in the room: IT labour
Let's calculate the real numbers.
On-premises true cost breakdown
Hardware costs (amortised)
For a production server suitable for .NET applications:
| Item | Cost | Lifespan | Monthly (amortised) |
|---|---|---|---|
| Server (Dell PowerEdge R450 or similar) | £2,500 | 3 years | £69.44 |
| Network equipment (firewall, switch) | £750 | 5 years | £12.50 |
| UPS (uninterruptible power supply) | £400 | 5 years | £6.67 |
| Backup NAS | £800 | 4 years | £16.67 |
| Cabling and accessories | £200 | 5 years | £3.33 |
| Hardware subtotal | £4,650 | £108.61/month |
Round to £111/month for hardware costs.
Operational costs
| Item | Monthly cost | Notes |
|---|---|---|
| Electricity (200W average) | £35 | 730 hours x £0.24/kWh x 200W |
| Business internet (100Mbps) | £75 | Leased line or business broadband |
| Climate control (additional HVAC) | £25 | Cooling server area |
| Insurance (equipment coverage) | £15 | Business equipment insurance |
| Maintenance budget | £25 | Parts, replacements, repairs |
| Operational subtotal | £175/month |
Infrastructure total (excluding labour)
Hardware (amortised): £111/month
Operational costs: £175/month
─────────────────────────────────────
Infrastructure total: £286/month
But we're not done yet.
IT management labour
This is the cost most people underestimate or ignore entirely.
What on-premises management requires:
| Task | Monthly hours | Notes |
|---|---|---|
| Security patches and updates | 2-3 hours | OS, application, firmware |
| Backups verification | 1-2 hours | Test restores, monitoring |
| Monitoring and alerts | 1-2 hours | Reviewing, tuning |
| Hardware health checks | 0.5-1 hour | RAID status, drive health, logs |
| Incident response | 2-4 hours | When things go wrong |
| Documentation | 0.5-1 hour | Keeping procedures current |
| Total | 7-13 hours/month | Conservative range |
Labour cost calculation:
At £50/hour (reasonable for UK IT support/DevOps):
Monthly hours: 10 hours (midpoint)
Labour cost: £500/month
True total cost of ownership
Hardware (amortised): £111/month
Operational costs: £175/month
IT management: £500/month
─────────────────────────────────────
Total monthly TCO: £786/month
Round to approximately £771/month for a realistic on-premises cost.
Cloud cost comparison
Now let's compare to cloud options:
| Option | Monthly cost | vs On-premises |
|---|---|---|
| On-premises (full TCO) | £771 | - |
| Azure (recommended) | £93 | 88% cheaper |
| DigitalOcean | £37 | 95% cheaper |
| Hetzner Cloud | £14 | 98% cheaper |
Cloud is not 3x cheaper. It's 8-55x cheaper when you account for all costs.
Three-year total cost comparison
| Approach | Year 1 | Year 2 | Year 3 | 3-year total |
|---|---|---|---|---|
| On-premises | £9,252 | £9,252 | £9,252 | £27,756 |
| Azure | £1,116 | £1,116 | £1,116 | £3,348 |
| DigitalOcean | £444 | £444 | £444 | £1,332 |
| Hetzner | £168 | £168 | £168 | £504 |
Over three years:
- Switching to Azure saves £24,408
- Switching to DigitalOcean saves £26,424
- Switching to Hetzner saves £27,252
These savings fund a lot of product development.
The only 3 scenarios where on-premises makes sense
1. Compliance mandates physical control (rare)
Some regulations require physical control of hardware:
- Certain government contracts (though cloud government regions exist)
- Specific financial services requirements (though most now accept certified cloud)
- Military or defence applications
Reality check: Most compliance requirements can be met with cloud providers' compliance certifications (ISO 27001, SOC 2, etc.). Genuine physical control requirements are rare.
Questions to ask:
- Does the regulation specifically require on-premises, or just "appropriate security"?
- Do cloud providers with relevant certifications satisfy the requirement?
- Is the on-premises requirement actually about data residency (solvable with UK cloud regions)?
2. Air-gapped environment required
Some environments genuinely cannot connect to the internet:
- Industrial control systems (SCADA)
- Classified information processing
- Certain research environments
If you need an air-gapped environment, cloud is obviously not an option.
Reality check: True air-gap requirements are uncommon. Many "air-gapped" requirements are actually about network isolation - achievable with private cloud VPCs.
3. Running 10+ applications (cost sharing)
The economics change when you're running many applications on shared infrastructure.
Single application:
- On-premises: £771/month for one app
- Cloud: £93/month for one app
- Winner: Cloud (8x cheaper)
Ten applications:
- On-premises: £771/month shared across 10 apps = £77/app
- Cloud: £93 x 10 = £930/month = £93/app
- Winner: On-premises (17% cheaper)
But there's a better option...
Dedicated servers: the middle ground
If you need to run multiple applications and have DevOps expertise, dedicated servers offer the best of both worlds:
Hetzner dedicated server (£33/month)
For £33/month, you get:
- AMD Ryzen 5 3600 (6-core processor)
- 64GB ECC RAM
- 2x512GB NVMe SSD
- Unlimited traffic (1Gbps)
- Professional data centre
- No power, cooling, or internet costs
Running 5 applications:
Dedicated server: £33/month
Applications: 5
Cost per app: £6.60/month
Compared to:
- Cloud (DigitalOcean): £37/app = 5.6x more expensive
- On-premises: £77/app = 11.7x more expensive
Dedicated servers capture the cost-sharing benefits of on-premises without the operational burden.
OVHcloud dedicated (£31/month)
For UK data residency:
- Intel Xeon-D processor
- 32GB RAM
- 2x512GB NVMe
- UK data centre available
- Unlimited bandwidth
Running 5 applications:
Dedicated server: £31/month
Applications: 5
Cost per app: £6.20/month
Who should consider dedicated servers:
- Web agencies running client sites
- MSPs hosting customer applications
- Internal IT running multiple business applications
- Development shops with many projects
Requirements:
- Strong Linux/DevOps skills
- Ability to self-manage Kubernetes (k3s) and databases
- Comfort with self-managed security and backups
Migration path: on-premises to cloud
If you're currently on-premises and want to migrate, here's a practical approach:
Phase 1: Assessment (1-2 weeks)
Inventory your applications:
- What's running?
- What are the dependencies?
- What's the resource utilisation?
- What data sensitivity exists?
Document your infrastructure:
- Current hardware specifications
- Network architecture
- Backup procedures
- Monitoring and alerting
Identify constraints:
- Compliance requirements
- Data residency needs
- Integration dependencies
- Team expertise
Phase 2: Choose your target (1 week)
Based on your assessment:
| If you need... | Consider... |
|---|---|
| Simplicity + managed services | Azure, DigitalOcean |
| Lowest cost + DevOps skills | Hetzner Cloud, dedicated servers |
| UK data residency | Azure UK, DigitalOcean London, OVHcloud UK |
| Zero infrastructure work | PaaS (Render, Railway) |
Phase 3: Lift and shift vs re-architecture
Lift and shift (faster, lower risk):
- Containerise existing applications with Docker
- Deploy containers to cloud Kubernetes or container service
- Migrate databases with backup/restore
- Update DNS and networking
Re-architecture (slower, better long-term):
- Refactor applications for cloud-native patterns
- Adopt managed services (databases, caching, queues)
- Implement Infrastructure as Code
- Design for horizontal scaling
Recommendation: Start with lift and shift, then optimise over time.
Phase 4: Migration execution (2-6 weeks)
Week 1-2: Non-production
- Deploy development/staging environments
- Validate functionality
- Train team on new platform
Week 3-4: Production preparation
- Mirror production data
- Configure monitoring and alerting
- Set up backup procedures
- Document rollback plan
Week 5-6: Production cutover
- Blue-green deployment or DNS cutover
- Keep on-premises running for rollback
- Monitor closely
- Address issues promptly
Phase 5: Decommission (after 4-8 weeks stable)
- Remove on-premises infrastructure
- Cancel maintenance contracts
- Repurpose or sell hardware
- Document lessons learned
Typical timeline: 2-3 months for a straightforward migration, 4-6 months for complex environments.
Common objections addressed
"But I already own the hardware"
Sunk cost fallacy. The hardware cost is already spent whether you use it or not.
The question is: what costs less going forward?
- Continuing on-premises: £286/month (infrastructure) + £500/month (labour) = £786/month
- Migrating to cloud: £37-93/month (DigitalOcean/Azure)
Even if you've just bought new hardware, migrating saves money within months.
"Cloud is a recurring cost, hardware is one-time"
Hardware is not one-time:
- It needs replacement every 3-5 years
- It requires ongoing power, cooling, and maintenance
- It demands ongoing labour for management
Cloud is a recurring cost. On-premises is also a recurring cost - just less visible.
"We have IT staff anyway"
Are they spending their time on value-adding activities or infrastructure maintenance?
IT staff time spent on:
- Patching servers: Low value (cloud handles this)
- Monitoring hardware: Low value (cloud handles this)
- Building products: High value
Moving to cloud frees IT staff to work on things that matter.
"What about internet outages?"
Valid concern. On-premises can continue operating without internet (for internal applications).
But consider:
- How often does your internet actually go down?
- Can users access internal applications during an internet outage anyway (if working remotely)?
- Do modern business processes require internet regardless?
For most organisations, internet availability is effectively required for business operations.
"Security concerns about cloud"
Cloud security is typically superior to on-premises:
| Aspect | On-premises | Cloud |
|---|---|---|
| Physical security | Your building | Purpose-built data centre |
| Security updates | You apply them | Automatic/managed |
| Monitoring | You build it | Built-in |
| Compliance certs | You achieve them | Already certified |
| Security team | Your budget | Hyperscaler security budget |
Azure, AWS, and GCP have security teams larger than most companies. They're better at security than most organisations can be.
Decision framework
Move to cloud when:
- You're running 1-5 applications
- You don't have dedicated infrastructure staff
- Compliance doesn't mandate physical control
- You want to focus on products, not infrastructure
- You value predictable, lower costs
Consider dedicated servers when:
- You're running 5+ applications
- You have DevOps expertise
- Lowest cost is the priority
- Self-management is acceptable
- Data residency is flexible
Stay on-premises when:
- Compliance genuinely mandates physical control
- Air-gapped environment is required
- You're running 10+ applications with dedicated staff
- Existing infrastructure is already amortised and efficient
Summary
On-premises hosting costs 7-10x more than cloud when you account for all costs:
| Approach | Monthly TCO | 3-year total |
|---|---|---|
| On-premises (full cost) | £771 | £27,756 |
| Azure | £93 | £3,348 |
| DigitalOcean | £37 | £1,332 |
| Hetzner Cloud | £14 | £504 |
| Dedicated server (5 apps) | £33 | £1,188 |
The myth persists because people compare hardware purchase price to cloud monthly fees - ignoring power, cooling, internet, maintenance, and most importantly, labour.
For most UK businesses:
- 1-5 applications: Cloud (DigitalOcean, Azure)
- 5+ applications with DevOps skills: Dedicated servers (Hetzner, OVH)
- Compliance mandates physical control: On-premises (but verify the requirement)
The cloud vs on-premises debate was settled years ago. Cloud won - and the margin isn't close.
