# Overview

> What You host is and how the platform is organized.

- Web page: https://documentation.federated.computer/platform/coreplatform/getting-started/overview/

You host is a software platform that runs on virtual machines you provision at your cloud provider of choice. You bring the compute infrastructure; Federated supplies **CoreServer** — a custom operating system — and **Cores** — bundles of open source business software that run on top of it.

A **Core** is a bundle of open source apps (such as Nextcloud, Gitea, and Vaultwarden) built to work together out of the box, running on **CoreServer** on your own VM. Cores are tied to your account and backed by a set of **domains** that route traffic to your environment. Each Core can also be equipped with optional add-on services like monitoring and backups.

## What You Get

- CoreServer and your chosen Core software bundle installed on your own VMs, managed through the Federated platform
- At least three domains — either free Federated-managed domains, or custom domains you purchase and register through the platform
- An SSH key pair automatically generated at checkout, used by the Provisioner to configure your Cores
- A billing structure based on your chosen plan tier, with transparent per-Core pricing
- A team workspace where you can invite colleagues at different permission levels

## How the Platform Is Organized

Your account is the top-level container for everything: your Cores, domains, users, and billing. One person signs up as the **Owner** and completes checkout; from there, additional team members can be invited. All Cores and domains belong to the account, not individual users.
