A cloud-only platform is convenient, but it often comes with recurring fees, usage limits, and less control over data and customization.
A self-hosted solution gives your organization full ownership of where the system runs, how data is stored, and how features are extended.
In practice, many teams adopt a hybrid strategy: self-host the core systems (identity, storage, CRM, ERP) while using cloud services only where they bring clear benefits.
When Self-Hosting Is the Better Choice
- Data ownership & privacy: keep sensitive data under your control
- Compliance & data residency: choose where data physically lives
- Predictable cost: scale by infrastructure, not per-user pricing
- Deep customization: modify workflows, permissions, and integrations
- Vendor independence: avoid sudden price changes or feature removals
When Cloud-Only Is the Better Choice
- Very small teams: no IT resources for maintenance
- Ultra-fast launch: you need a solution deployed in hours
- Highly managed needs: vendor-managed uptime and SLAs are mandatory
- Standard workflows: your needs fit the SaaS product “as-is”
Comparison: Self-Hosted vs Cloud-Only
| Aspect | Self-Hosted | Cloud-Only |
|---|---|---|
| Upfront Setup | Higher (deployment + configuration) | Lower (sign up and use) |
| Ongoing Cost | Infrastructure + support | Subscription + usage-based fees |
| Customization | High | Limited to product settings |
| Data Control | Full control | Vendor-controlled |
| Vendor Lock-In | Low | Often high |
| Compliance / Residency | Flexible (you choose region) | Depends on vendor |

| Make (Integromat) | Node-RED | Lightweight flows, great for IoT + APIs |
Recommended Approach: Hybrid by Default
For many organizations, the best practical path is hybrid:
self-host the systems where data control and customization matter most,
and use cloud services only where they provide clear advantages.
If you want a clear decision framework, start with three questions:
- Is the data sensitive or regulated? If yes, self-hosting often wins.
- Do you need deep customization or integration? If yes, self-hosting wins.
- Do you have IT support (internal or partner)? If yes, self-hosting becomes easy and sustainable.
