# SaaS vs your cloud vs on-premise for a voice agent

CallWhiz AI offers the same platform as SaaS, inside your own cloud account, or on your own hardware. SaaS is live today; in-cloud and on-premise deployments are scoped first and live in about 30 days.

## Definitions

- **Boundary:** The network or account that call audio and data stay inside.

## SaaS

CallWhiz AI hosts the platform. Sign up, build an agent, put it on a number, and be live today, paying per minute from credits with no monthly commitment.

## Your cloud

The platform runs inside your own AWS, Azure or GCP account, so call audio never leaves your boundary. The deployment is scoped first, then live on real calls in about 30 days.

## On-premise

Bare metal or Kubernetes, for networks with no cloud at all. Scoped first, then live in about 30 days, with the same features as the other two modes.

## What does not change between modes

The feature set. SSO and role-based access, data residency by region, multi-tenancy and a 99.9% uptime SLA are available when you need them in any mode, and are not required to start.
