The Real Question
Cloud versus on-premise is a choice about who runs the servers, how you pay, and what happens when the internet or the hardware fails. Both can be secure and reliable; they fail differently.
Cost Shape
- Cloud: low upfront, predictable monthly fee per user or per doctor, updates included. Costs scale with usage.
- On-premise: large one-time licence plus server hardware, then annual maintenance at roughly fifteen to twenty per cent of the licence. Cheaper over many years if volume is stable and you have IT staff.
Maintenance and Updates
- Cloud: the vendor patches, upgrades and backs up. You get compliance updates such as ABDM automatically.
- On-premise: your responsibility, or a paid AMC. Updates can lag, which matters for regulatory changes.
Uptime and Failure Modes
- Cloud fails when your internet drops. Mitigate with a second connection and, ideally, an offline mode that syncs later.
- On-premise fails when the server, power or a disk fails. Mitigate with a UPS, generator, RAID and a tested restore.
Data Control and Residency
- On-premise keeps data physically in your building, which some institutions require.
- Cloud data sits in the vendor's data centre. Ask where it is hosted, that it is in India if that matters to you, and how you export it on demand.
A Simple Guide
- Solo, small, or multi-site clinic: cloud. Lower cost, no IT burden, access from anywhere.
- Hospital with strong IT and strict data-residency rules: on-premise or a private cloud.
- Unreliable local internet: cloud with a mandatory offline mode, or on-premise with cloud backup.
Non-Negotiables Either Way
Off-site backups, a tested restore, encryption, audit logs, and a contractual right to export your data in a standard format.
