Resizing a server

Resize the resources available to your JupyterHub
=================================================
As you are using your JupyterHub, you may find that you have a need to increase or decrease
the amount of resources allocated to your TLJH install. How resources can be reallocated
will depend on the server interface; consult the installation page for your provider for

As you are using your JupyterHub, you may need to increase or decrease
the amount of resources allocated to your TLJH install. The kinds of resources that can be
allocated, as well as the process to do so, will depend on the provider / interface for your
VM. We recommend consulting the installation page for your provider for more information. This
page covers the steps your should take on your JupyterHub *after* you've reallocated resources on
the cloud provider of your choice.
However, once resources have been relocated, you must tell TLJH to make use of these resources,
Currently there are instructions to resize your resources on the following providers:

Verifying a Resize

#. Once you have resized your server, you will need to tell the JupyterHub to make use of
these new resources. To accomplish this, you will follow the instructions in

using the terminal in the JupyterHub. It can also be completed through the terminal.

a new server (if you had one previously running, click "Control Panel -> Stop My Server" to
shut down your active server first), opening a notebook, and checking the value of the
