What is on-premises deployment?

On-premises deployment is software running on infrastructure the customer controls. Where data goes and who can support it still depend on the contract.

Where this one gets misread

On-premises is used loosely for a private tenancy or a dedicated instance in somebody else's data centre. Those differ in who can physically reach the machine and who is responsible when it stops, which is usually the reason the question was asked.

Questions to ask

Ask for a worked example on your own material, and the evidence needed to reproduce it.

  • Whose hardware, in whose building?
  • Who holds administrative access?
  • How are updates applied, and by whom?
  • What still calls out to the internet, and for what?

How Marella uses the term

We use “On-premises deployment” only where a product mechanism or an evaluation method backs it up, and we say when the behaviour depends on how a deployment is configured.

  • Backed by a product mechanism or an evaluation method
  • Deployment differences flagged
