On-prem vs Cloud

What it means, why it matters to your business, and where it shows up in a real build decision.

In plain terms

On-premise means running AI on infrastructure you own and control, while cloud means using shared infrastructure rented from a provider. Most teams should start in the cloud for speed. On-premise becomes worth its higher cost mainly when data residency, compliance, or scale demand it.

A simple analogy

Cloud is renting a hotel room. On-premise is owning a house. The hotel is ready immediately, managed by someone else, and priced per night. The house is yours to configure, costs more upfront, and you handle the plumbing.

What it looks like in practice

A government agency evaluates cloud AI but data sovereignty rules require all processing to stay within national borders. They deploy an open-weight model on government-managed infrastructure.

When to use it

Start in the cloud. Move on-premise when a hard compliance requirement mandates it, when inference volume makes per-token pricing uneconomical at scale, or when the data cannot legally leave your infrastructure.

When to avoid it

Do not go on-premise to save money at early scale. The infrastructure, DevOps, and model management overhead will cost more than cloud pricing until you reach significant, stable volume.
