Cloud vs on-premise ERP
Short answerCloud ERP runs on a provider's data centres and is accessed over the internet, with lower upfront cost and less IT work. On-premise ERP runs on your own servers, giving maximum control and offline resilience but requiring IT staff and hardware. Data-residency rules, such as Saudi Arabia's PDPL, can make in-country cloud regions or on-premise deployment necessary.
Comparison
| Factor | Cloud ERP | On-premise ERP |
|---|---|---|
| Upfront cost | Low | Higher: servers and licences |
| IT effort | Low | High |
| Control | Shared with provider | Full |
| Internet dependence | High | Low on site |
| Data residency | Choose an in-country region | Data stays on your site |
| Scaling | Easy | Needs hardware |
Data residency by region
- India: Digital Personal Data Protection Act 2023
- Saudi Arabia: PDPL restricts cross-border transfers; in-Kingdom regions are common
- UAE: federal PDPL, plus DIFC and ADGM regimes
- South Africa: POPIA
- Canada: PIPEDA; many organisations prefer Canadian regions
Which suits heavy industry?
Steel plants and mines often choose on-premise or hybrid deployments because plant-floor systems must keep running if internet connectivity fails. Smart Steel ERP supports both.
Frequently asked
Can we start on cloud and move on-premise later?
