Cloud or your own server: how the choice is actually made

The decision rarely turns on price, and almost never on technology. It turns on who in the company has to be responsible when something stops at three in the morning.

The cloud versus on-premise debate usually starts from the wrong question — where the data physically sits. That is the least important part of the decision, because data can be kept well or badly in either place. The question that actually decides is different: who in the company takes responsibility for availability, backups, security patches and recovery after a failure.

Everything else — cost, speed, security — follows from that single choice rather than standing as an independent criterion.

What actually differs

Cloud (SaaS)Your own infrastructure
Shape of the costSubscription, starts immediately, no capital outlayInvestment in hardware and licences, then maintenance
Who maintains itThe vendor — servers, backups, patches, monitoringThe company or its IT partner
UpgradesRegular, for all customers, in an agreed windowWhen the company decides — and finds the time
Recovery after failureDefined by contract, tested by the vendorAs good as it has been tested internally
Control over the environmentStandardised; changes go through configurationComplete, including versions and network
Working without internetDoes not work without a link to the centreWorks on the local network

Where cloud genuinely wins

  • **No dead capital.** Cost follows usage instead of being paid up front and depreciated.
  • **Maintenance is someone's job under contract**, not something done when there is time. This is the largest hidden advantage: in companies without a dedicated administrator, backups get made until the day they are needed.
  • **Upgrades arrive regularly**, so the system does not drift away from current regulation. For e-invoicing, VAT records and fiscalization that is not a convenience but a condition of operating.
  • **Growth does not require procurement.** Thirty new users is a line in a contract, not a new machine.

Where on-premise genuinely wins

  • **When regulation or a contract requires it.** Some industries and some customers contractually require data to stay on a given network or in a given country.
  • **When infrastructure is maintained anyway.** A company that already has an administrator, a server room and recovery procedures pays a smaller difference.
  • **When production or the warehouse must run without a link.** A line that stops because the internet went down costs more than any subscription.
  • **When version control matters.** A system upgraded only after internal validation requires the company to choose the moment.

Security: where the argument goes wrong

It is widely assumed that data on your own server is safer because it is closer. In practice the opposite is more common: a serious cloud carries encryption, segmented networks, monitoring, regular patching and tested recovery, while a server in the office often has none of that — not because it is a bad choice, but because nobody is there to maintain it.

The honest comparison reads: an on-premise installation can be safer, but only if the company actually does what a cloud vendor does under contract. If it does not, proximity to the data is not an advantage but an illusion.

What to ask before deciding

  1. How long can the company afford not to work if the system stops — an hour, a day, a week? The answer determines everything else.
  2. Who makes the backups today, and when was recovery from them last verified?
  3. Is there an availability agreement, with a number in it, or only goodwill?
  4. How is the system upgraded when the law changes — and who bears the cost of that upgrade?
  5. In what form does the company get its data back if it changes vendor or model?
  6. Does the same system even run in both models, or does switching mean changing product?

That last question matters more than it looks. A system that exists only as cloud ties the company to one model permanently; a system that runs in both leaves the choice open later too. NG One runs in the cloud, on your own infrastructure and hybrid, on the same core — which means the delivery model stays a decision that can be changed without replacing the system.
