Cloud software removes the server room from your hospital. It does not remove the questions about internet, data ownership and law. This guide takes those questions in the order a hospital owner should ask them.
Cloud based hospital management software is a hospital system that runs on servers owned and maintained by the vendor, while your staff use it through a web browser. You pay a subscription instead of buying a server and a licence. Registration, OPD, IPD, billing, pharmacy, lab and reports all sit in one database that the vendor hosts and backs up.
The label is used loosely, and the loose use costs buyers money. Three quite different products get called cloud:
Ask which of the three you are being sold. The answer decides who patches the server, who restores a backup after a failure, and who answers for a security incident.
Whichever model you choose, patient data travels between your desk and the vendor's server across the public internet, protected by TLS encryption. That is normal, and it is also why the internet connection deserves its own section further down.
Vendors on both sides oversell. This table sets out the trade offs as they actually apply to a hospital that has a small IT team or none.
| Point | Cloud based | On premise |
|---|---|---|
| Setup | Browser access and no server purchase, so a hospital can start soon after its data is ready | Server, UPS, licence and installation before first use |
| Upkeep | Vendor patches, monitors and backs up | Your team or an AMC vendor patches and backs up |
| Updates | Arrive continuously, sometimes with little notice | You schedule them, but they are often delayed for years |
| What can stop you | Your internet line and the vendor's availability | Server hardware, power and your own backup discipline |
| Data control | Data sits with the vendor under a contract, so the wording of that contract matters | Data sits in your building under your physical control |
| Cost pattern | Regular subscription, low upfront spend | Large upfront spend, then a smaller yearly maintenance cost |
| Several branches | One shared record by default | Needs VPN links or separate servers between sites |
| Growth | Add users or branches by changing the plan | Buy hardware ahead of growth |
Neither model is safer by default. A well run cloud provider often has better physical security, patching and backup discipline than a small hospital's server cupboard. A badly run one is worse than that cupboard, because your data sits with a company you cannot inspect. The difference lies in evidence, so the useful question is never whether a system is cloud, it is what the vendor can show you.
The most common on premise failure is not a cyber attack. It is a single server with a backup that nobody has ever tested by restoring it. The most common cloud failure is a hospital that signed without a downtime plan and without an exit clause. Both are avoidable, and the rest of this guide is about avoiding them.
Cloud software depends on the connection between your desk and the vendor. When the line drops, the software cannot be reached. Most cloud hospital systems have no offline mode, and OneCity is one of them: it has no offline capability and no local sync layer, and we say so plainly. If any vendor tells you their product works offline, ask them to pull the network cable during the demo.
What we did about it on our side is keep the application light. OneCity is built as server rendered pages without a single page application framework and without a build step, and it is designed to render on a 2 Mbps line. A registration desk does not need a fat connection. It needs a connection that stays up.
Check the numbers before you sign. Measure the real speed and stability at the exact desks where the software will run, at busy hours, for a full week. A speed test at 11 at night from the manager's office tells you very little about a crowded OPD counter at 10 in the morning.
Text based screens are light. Scanned documents and radiology images are not. If your plan includes imaging, treat that traffic separately from everyday registration and billing, and ask the vendor how images are stored and retrieved. OneCity's PACS bridge is built but has not been tested against a live modality, so we describe it as PACS ready, and we would want to test against your equipment before promising anything more.
Moving to the cloud does not move responsibility. Under the Digital Personal Data Protection Act, 2023, the hospital is the Data Fiduciary and the software vendor is a Data Processor. The Act keeps the fiduciary responsible for processing done on its behalf, and a processor may be engaged only under a valid contract. In plain terms, if the vendor is careless, the hospital still answers for it.
The DPDP Rules, 2025 were notified on 14 November 2025 with an eighteen month period for phased compliance, according to the Press Information Bureau release. The Act also provides for a penalty of up to ₹250 crore for failure to maintain reasonable security safeguards. Check the notified schedule on the MeitY website for the dates that apply to your hospital, and read our DPDP Act guide for hospitals for the duties in hospital terms.
The CERT-In directions of 28 April 2022 apply to service providers, intermediaries, data centres, body corporate and government organisations. Three duties matter to a hospital buyer. Specified cyber incidents must be reported to CERT-In within 6 hours of noticing them. Logs must be kept securely for a rolling 180 days within Indian jurisdiction. System clocks must be synchronised with the Network Time Protocol servers of NIC or NPL. A cloud vendor should be able to tell you how it meets each one, and what it will do to help you if an incident touches your patients' data.
The DPDP Act does not set a blanket rule that all data must stay in India. It allows transfers outside India except to countries the Central Government restricts by notification, and other sector rules can be stricter. So do not accept a vague answer. Ask for the hosting location in writing, including the backup location, and ask whether any sub processor outside India can see patient data.
Three more checks belong here. Role based access and audit trails should be on by default, which our guide to role based access under DPDP explains. Backups should be tested, not just scheduled, and the guide on hospital ERP data security and backup covers what to ask. And if you plan to exchange records under the Ayushman Bharat Digital Mission, consent handling matters, which the ABDM and ABHA integration guide covers. Our wider compliance hub lists the rest.
These work on any vendor, including us. Ask them in writing and keep the answers with the contract.
One more question has become necessary. If the product has AI features, ask which AI providers can see patient data. OneCity's AI layer uses Anthropic's Claude by default, and other model providers can be set per hospital. Whichever vendor you choose, an AI provider is one more sub processor, and it belongs in the contract and in your consent wording.
Vendors price in four common ways: per user, per bed, per module, or as a flat tier for the whole hospital. Each looks cheap for a different kind of hospital. Per user pricing suits a hospital with few staff on the system. Per bed pricing suits a hospital with high staff numbers but low occupancy. Flat tiers are easier to budget but can hide limits.
Read the offer for lines that appear later:
Compare offers over five years, and add the cost of the backup internet line and the network power backup to the cloud side. For the on premise side, add the server, the UPS, the yearly maintenance contract and a part share of a technician. We deliberately do not quote a market average here, because published averages for Indian hospital software vary too much by bed count and module list to be useful. Your own quotes are the only numbers that count. Our hospital software pricing guide explains the pricing models in more detail, and our pricing page shows ours: OneCity is free for up to 5 doctors, with no setup fee and no card required.
A sensible cutover starts where errors are cheapest to fix. Begin with registration and billing at one counter, then add OPD consultation, then IPD and pharmacy once the front desk is comfortable. Our ERP implementation timeline guide lays out the order in more detail.
Data migration is where most delays start. Import active patients and open balances first, and keep older records readable in an archive instead of forcing a full import. Clean duplicate patients before the import, because a duplicate created in the old system becomes a permanent duplicate in the new one. The patient master and UHID is the record everything else attaches to, so it deserves the most care. If you plan to link ABHA numbers at registration, see the ABHA linkage module.
Run the old and new systems in parallel for a short period on one department, and compare a day's bills line by line. Train the front desk before the doctors, since registration errors travel furthest.
A group with more than one site gets the clearest benefit from cloud. Every branch reads and writes the same patient record, so a patient seen in one town is not a stranger in the next. Reports for the owner cover all sites without collecting spreadsheets. Consent captured at one branch is visible at every other, which matters under DPDP. The multi location hospital ERP page covers the wider case, and patient referral tracking shows how a referral between branches keeps its history instead of starting again. The same shared record also powers hospital CRM software for recall and reminders across all sites.
Take a hypothetical hospital with 60 beds, a busy OPD, and a diagnostic collection centre 12 kilometres away. It has no full time IT person. Power cuts are frequent, and the only broadband provider in the area has had two outages in a year.
On the on premise path, the hospital buys a server and a UPS, hires a technician on a maintenance contract, and connects the collection centre through a VPN. The server cupboard becomes a single point of failure, the backup runs to an external disk that sits in the same room, and nobody has ever restored from it.
On the cloud path, the hospital takes a second connection from a mobile operator with an automatic failover router, puts a UPS under the router and the switch, and keeps paper forms at each counter. The collection centre logs in through a browser and sees the same patient record. The hospital asks the vendor for a restore test result, the hosting location and an exit clause before signing.
The cloud path is not free of risk. Both connections could fail on the same day, and that is what the paper forms are for. But the failure is now short, visible and planned for, which is a better position than a server failure that nobody has rehearsed.
We build a cloud product, and we still tell some hospitals that it is not the right fit. Consider on premise or a hybrid setup in these cases:
If your case is on this list, say so early in vendor conversations. A vendor who cannot discuss it honestly is showing you how the relationship will go.
Turn the questions above into five steps and do them in this order. Skipping step three is the mistake that hurts most.
OneCity is a cloud hosted hospital ERP and CRM built for tier 2 and tier 3 hospitals. The hospital management software page describes the whole product, and the module list shows how registration, OPD, IPD, billing, pharmacy and lab connect on one patient record. The pharmacy module, for example, works from the same patient record as the rest of the system. Related workflows have their own pages, including OPD queue management and IPD and bed management.
Some plain statements, since trust depends on them. OneCity has no offline mode. It is ABDM ready, not ABDM certified. Its PACS bridge is PACS ready and not tested against a live modality. We would rather you hear these limits from us before a demo than discover them after go live. You can try the product free for up to 5 doctors, or book a demo and bring your connectivity questions with you.
It is a hospital system that runs on servers owned and maintained by the vendor and is used through a web browser. The hospital pays a subscription instead of buying a server. Registration, OPD, IPD, billing, pharmacy and lab data sit in one database that the vendor hosts and backs up.
It can be, but safety depends on the vendor's controls and on your contract, not on the word cloud. Under the DPDP Act 2023 the hospital stays responsible as the Data Fiduciary even when a vendor processes the data. Ask for the hosting location, backup and restore evidence, access logs, an incident process and a written data processing contract.
Most cloud hospital systems do not. OneCity has no offline mode. If your site cannot keep a stable connection, fix connectivity first with two lines from different providers and automatic failover, or consider an on premise or hybrid product.
It depends on how you count. Cloud moves cost from a large upfront purchase to a regular subscription. On premise adds a server, power backup, an annual maintenance contract and a technician. Compare both over five years using real quotes, and include the cost of a backup internet line for cloud.
The DPDP Act 2023 does not set a blanket rule that all data must stay in India. It allows transfers outside India except to countries the Central Government restricts by notification, and other sector rules can be stricter. Ask the vendor for the hosting and backup location in writing.
The hospital should own its patient data. The contract should say so, limit the vendor to using the data only to provide the service, allow a full export at any time, and require written proof of deletion when the contract ends.
