# Servers

The "Servers" menu lets a user declare new servers on previously declared infrastructures, deploy servers (instances) to the cloud providers or to declare servers on-prem on existing infrastructures, as per the settings defined in the declaration form and act on these servers.

As with the infrastructure menu, selecting a server from the list using the checkbox unlocks the list of actions a user can take to interact with the server.

Once selected, user can edit the server definition, start and stop the server, deploy it to its attached infrastructure, attach/detach secrets, destroy the server at provider end or delete its configuration from the YaK inventory.

{% hint style="warning" %}
Prior to deploying servers:\
\- An infrastructure must exist\
\- Cloud provider secrets and SSH key (for Linux servers) or WinRM certificate (for Windows servers) must have been created and attached to the server or to the infrastructure\
\- To create a Windows Server on AWS, not only a cert\_key for winrm is required, but also a sshkey. This is specific to AWS and is required to recover the Windows Server Administrator password from AWS Portal.
{% endhint %}
