Cloud and on-premise, defined
Cloud ERP is hosted on servers in a data centre, managed by the vendor or a hosting provider. Users connect through a browser or mobile app over the internet. Backups, security patches and capacity are handled for you, usually as part of a yearly or monthly fee.
On-premise ERP is installed on a server you own, in your plant or office. Users connect over the local network, and remote users through a VPN or similar. You are responsible for the server, power backup, operating system, backups and replacement hardware.
There is also a hybrid arrangement: the main system in the cloud with small local components, such as weigh-scale or label-printer connectors, at the plant. For most manufacturers the choice is simply where the database lives.
Side-by-side comparison
| Factor | Cloud ERP | On-premise ERP |
|---|---|---|
| Upfront cost | Low: no server to buy | Higher: server, UPS, backup storage, licences |
| Recurring cost | Subscription or hosting fee | Support, power, hardware replacement every few years |
| Internet dependence | High: the plant needs a reliable connection | Low: works on the local network |
| Power cuts | The data centre stays up; the plant needs power for its own devices | The server needs UPS or generator backup |
| Remote access | Built in, from anywhere | Needs VPN or remote access setup |
| Multiple plants | Simple: everyone connects to one system | Needs links between sites or a central server |
| Backups | Managed by the provider | Your responsibility; must be tested |
| Updates | Applied centrally | Applied on your server, sometimes with downtime |
| Data control | Data in a data centre under a contract | Data on hardware you own |
| IT staff needed | Minimal | Someone to look after the server and network |
Internet and power: the Indian plant reality
In many industrial areas the deciding factor is not cost but connectivity. A cloud ERP is only as available as the plant's internet. Before deciding, check honestly:
- How often does the internet go down, and for how long?
- Is there a second connection from a different provider, or a mobile data backup?
- Do floor devices (gate phones, store terminals) have Wi-Fi coverage where they are used?
- Is there UPS or generator power for the router as well as the computers?
With two connections from different providers and power backup on the network equipment, cloud ERP works well in most Punjab and Haryana industrial estates we visit. Where that is not possible, an in-plant server avoids stopping the gate and store when the line drops.
A second broadband line from a different provider usually costs less in a year than one lost day of dispatch.
Security and data ownership
Owners sometimes assume that data on their own server is safer. In practice security depends on how each option is run. A well-managed data centre has physical security, redundant power and professional patching that few plants can match. An in-plant server is safe from internet outages but exposed to local risks: theft, fire, water, a failed disk with no tested backup, or a shared password.
Whichever you choose, confirm in writing:
- The data belongs to you, and can be exported in full
- Backups are taken daily and kept off the main server
- Restores are tested, not just backups taken
- Access is role-based, with individual logins
- Every document has an audit trail: who, what, when
- Connections are encrypted
Several plants, or owners on the move
For groups with more than one plant, or owners who travel, cloud ERP is usually simpler: every location and every phone connects to the same system, and consolidated reports need no synchronisation. On-premise multi-plant setups are possible but need reliable links between sites or a central server reachable by all of them, which brings back the internet question in a different form.
How to decide
| If this describes you | Lean towards |
|---|---|
| Reliable internet with a backup line | Cloud |
| More than one plant or warehouse | Cloud |
| Owner or managers need access while travelling | Cloud |
| No in-house IT person | Cloud |
| Frequent long internet outages, no backup possible | On-premise |
| Restricted internet by customer or policy | On-premise |
| Existing server room and IT staff | Either |
eManage runs with the same features on the cloud or on a server in your plant, and the choice can change later without changing editions. Most of our clients run on the cloud; units with restricted internet run on a plant server.
Questions buyers ask
Is cloud ERP safe for manufacturing data?
Yes, when the provider uses encrypted connections, role-based access, daily off-site backups and tested restores. Ask the vendor to confirm each in writing, and confirm that the data belongs to you.
What happens to a cloud ERP when the internet goes down?
Users at the plant cannot reach it until the connection returns. A second line from a different provider, or mobile data backup, keeps most plants running through outages.
Can we move from on-premise to cloud later?
With eManage, yes. The same editions run in both places, so moving is a data migration, not a new implementation.
Which is cheaper, cloud or on-premise ERP?
Cloud is cheaper to start; on-premise has a higher first-year cost and lower yearly cost. Over five years the totals are often close. See how much ERP costs.
Do floor devices work with a cloud ERP?
Yes. Android apps, weigh scales and label printers connect over the plant network to the cloud system, provided the plant has Wi-Fi coverage at those stations.
