Choosing between cloud vs on-premise CMMS software can be a game-changing decision for any maintenance department. While both options aim to streamline operations, track work orders, and reduce downtime, the deployment method can significantly impact your team’s flexibility, data security, and long-term cost.
In this blog, we’ll break down the key differences, share real-world examples, and help you decide which option is right for your facility.
What Is On-Premise CMMS?
On-premise CMMS software is installed locally on your organization’s servers or computers. Your IT team is responsible for maintaining the software, managing backups, and ensuring uptime.
✅ Pros:
- Full control over data and infrastructure
- Can operate without internet access
- Better suited for facilities with strict data regulations
❌ Cons:
- Requires in-house IT support
- Higher upfront cost for hardware and licensing
- Longer setup and upgrade cycles
What Is Cloud-Based CMMS?
Cloud CMMS is hosted on remote servers and accessed via a web browser. The vendor handles system updates, backups, and cybersecurity, and you typically pay a monthly or annual subscription fee.
✅ Pros:
- Access from anywhere, on any device
- Quick to deploy and scale
- No need for in-house server maintenance
- Automatic updates and backups
❌ Cons:
- Requires stable internet connection
- Data hosted off-site (some industries may have restrictions)
Real-Life Experience: A Power Plant’s Journey
At a 250 MW HFO-based IPP plant in Bangladesh, the maintenance team initially used an Excel-based system and later shifted to an on-premise CMMS. The software worked well—until a server crashed during a forced outage, delaying fault reports and spares tracking.
They later migrated to a cloud-based CMMS. Within weeks, team members could:
- Log issues directly from their phones
- Get real-time approvals for emergency work permits
- Track vendor delivery timelines from any location
“Before cloud CMMS, everything depended on who was physically present in the control room. Now, even our GM can approve emergency work orders while traveling.“

Key Comparison Table
| Feature | Cloud CMMS | On-Premise CMMS |
|---|---|---|
| Deployment Time | Hours to Days | Weeks to Months |
| Cost | Subscription-based (OPEX) | Upfront + Maintenance (CAPEX) |
| Accessibility | Anywhere with internet | On-site only |
| Data Security | Vendor-managed | User-managed |
| Scalability | Easy to scale | Hardware limitations |
| Offline Functionality | Limited (unless hybrid) | Fully functional offline |
Which One Should You Choose?
Choose Cloud CMMS if you:
- Have remote teams
- Want fast deployment
- Prefer lower upfront costs
- Lack in-house IT support
Choose On-Premise CMMS if you:
- Operate in a high-security environment
- Have strict regulatory requirements
- Have reliable IT infrastructure
- Prefer full data control
When comparing cloud vs on-premise CMMS software, your choice should align with your facility’s size, team structure, IT capabilities, and long-term goals. While on-premise systems give you more control, cloud-based CMMS platforms offer speed, agility, and ease-of-use—crucial for modern maintenance operations.
