# Hosts

Hosts (VMs) are a cornerstone of cloud infrastructure, essential for providing isolated, scalable, and flexible environments for running applications and services. Hosts can exist in various forms and configurations, depending on the environment and the technology stack.

**For instructions to create a Host in DuploCloud, see the documentation for your specific cloud provider:**

* [AWS Host](/docs/automation-platform/overview/use-cases/hosts-vms/adding-hosts.md)
* [Azure Host](/docs/automation-platform/overview-2/use-cases/hosts-vms.md#adding-a-host-vm)
* [GCP Host](/docs/automation-platform/overview-1/use-cases/hosts-vms.md#id-3-toc-title)

In DuploCloud, Hosts are virtualized computing resources provided by your cloud service provider (e.g., AWS EC2, Google Compute Engine, Azure VMs) or your organization's data center and managed by the DuploCloud Platform. They are used to provision scalable, on-demand infrastructure. DuploCloud abstracts the complexities of provisioning, configuring, and managing these Hosts. DuploCloud supports the following Host contexts:

* **Public Cloud**: VMs provided by cloud providers and managed through the DuploCloud Platform.
* **Private Cloud**: Virtualized environments managed within an organization's data center.
* **Combination of On-Premises and Cloud**: A mix of physical hosts, VMs, and cloud-hosted instances.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.duplocloud.com/docs/automation-platform/application-focused-interface-duplocloud-architecture/hosts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
