The verdict in three sentences
Managed public cloud (90,000-450,000 FCFA/month) stays the cheapest and most elastic, but forces data residency abroad that some regulated sectors cannot accept. Sovereign/local hosting (120,000-600,000 FCFA/month) costs 20 to 35 % more but cuts latency by 2 to 3 and keeps data in-country. The real question is not the monthly price but regulatory constraint and DR: add 30 to 50 % for tested backup and disaster recovery.
2026 cost and feature comparison
Here is the 2026 order of magnitude for hosting a mid-load business application (a few thousand users).
| Criterion | Managed public cloud | Sovereign / local |
|---|---|---|
| Monthly cost | 90,000 - 450,000 FCFA | 120,000 - 600,000 FCFA |
| Data residency | Abroad (EU/US) | In-country / region |
| Local-user latency | Baseline | Cut by 2 to 3 |
| Elasticity (scale-up) | Excellent | Medium to good |
| Backup + DR | +30 to 50 % | +30 to 50 % |
| Typical SLA | 99.9 % | 99.9 % |
| Regulated-sector fit | Limited | Suited |
A 99.9 % SLA means about 8.7 hours of downtime per year: barely acceptable for a critical app, which is why 99.95 % is often the target.
What really tips the decision
The monthly price is only the visible part. Three factors weigh more on 3-year total cost of ownership.
| Factor | TCO impact | Comment |
|---|---|---|
| Data residency | Blocking or neutral | Banking, health, public sector often constrained |
| Latency | +5 to +15 % conversion | A slow app loses users |
| Tested DR (RTO/RPO) | +30 to 50 %/month | Non-negotiable for a critical business app |
| Egress fees | 10,000-40,000 FCFA/month | Public cloud bills outbound bandwidth |
| Reversibility | Hidden cost | Add an exit clause in the contract |
Public-cloud egress fees often surprise: an app serving many files can see its real bill rise 15 to 25 %.
Mini case study
Sarah, CTO of an insurance firm in Singapore, weighs public cloud (180,000 FCFA/month) against sovereign (250,000 FCFA/month) for her claims-management application. The regulator mandates local residency of policyholder data: public cloud is ruled out. With tested DR (+40 %), sovereign lands at 350,000 FCFA/month, i.e. 4.2 M FCFA/year. Latency cut by 2.5 shaves 40 seconds off processing a case, so across 200 cases/day roughly 2.2 agent-hours saved per day — the 840,000 FCFA/year premium is absorbed in under a quarter.

FAQ
Is public cloud always cheaper?
On the sticker price, often yes, but egress and exit fees can inflate the bill by 15 to 25 %. Over 3 years, the gap with sovereign narrows sharply once DR and bandwidth are included.
What does data residency actually change?
It sets which country physically stores your data and under which jurisdiction. For insurance, banking or the public sector, a local constraint can make foreign public cloud simply non-compliant.
What does a 99.9 % SLA mean?
About 8.7 hours of tolerated downtime per year. For a critical app, target 99.95 % (4.4 h) or 99.99 % (53 min), which implies tested on-call and DR, hence a 30 to 60 % premium.
Do we always need DR?
For a critical business app, yes. A tested recovery plan with defined RTO/RPO adds 30 to 50 % to monthly cost, but it is the difference between hours and days of outage during an incident.
Can we switch hosts later?
Yes, but plan reversibility from the contract. Without an exit clause and documented export, migration can cost several months of billing in services.
