The short answer
The short answerThis is a question of conditions, not superiority. Data that must not leave the company, or production that must continue through a network outage, points on-premise. No operations staff, or several sites to consolidate, points to cloud.
Side by side
The same criteria applied to both.
| Criterion | On-Premise | Cloud |
|---|
| Where data sits | Internal servers — it does not leave | External data centre |
| During a network outage | Floor systems keep running | Unusable while the connection is down |
| Initial cost | Up-front investment in servers and licences | Little up front, often usage-based |
| Operations burden | You manage servers, backups and patching | Largely handled by the provider |
| Multiple sites | Needs per-site design and linking | Comparatively easy to consolidate |
| Scaling | Adding capacity takes time | Comparatively quick to expand |
Which one fits
The answer changes with conditions.
On-premise fits when
- Customer contracts or regulation restrict data leaving the company
- Production must continue through a network outage
- Process conditions and drawings are core assets requiring control
- You have the people and environment to run servers
Cloud fits when
- There is no in-house capability to manage servers
- Data from several sites has to be viewed together
- You want to limit up-front investment and grow in steps
- The use case — analytics and reporting — is unrelated to production continuity
Using both
The arrangement growing in manufacturing is execution on site, analytics in the cloud. Functions that must not stop — work orders, results — stay on the floor, while cross-site analysis and reporting sit in the cloud.
This requires being able to choose what is exported: aggregates or de-identified data rather than the full raw set.
The on-premise glossary entry sets out the criteria in more detail.
Quick AnswersOn-premise vs cloud — frequently asked
Questions that come up during comparison.
Does on-premise rule out remote support?
No. A remote access path aligned with your security policy is provided, typically logged and opened only when needed.
Is cloud less secure?
On technical measures alone, cloud is often stronger. The real question is whether contracts and regulation permit external storage.
Can we move later?
Yes, if portability is considered at design time. Data structures and integrations must not bind tightly to one environment.
Can AI features run on site?
Yes. U-Bot can be configured so internal documents never leave the company.
Which way do your conditions point?
Your current systems and site conditions narrow the options quickly.
