# AWS - Change Instance Type

## This is quick guide on how to resize an AWS EC2 Instance \*\*\* THIS IS AFTER HOURS WORK ONLY \*\*\*

This will be done mid-november leading up to the Holiday rush, then done again in mid-January after the holidays.

The first step in resizing an instance in our AWS environment is to disable the Lamda job that automatically restarts a server once it has entered a stopped state.

<iframe data-hsv-src="https://play-na2.hubspotvideo.com/v/243943054/id/258939292374" referrerpolicy="origin" sandbox="allow-forms allow-scripts allow-same-origin allow-popups" allow="autoplay; fullscreen;" style="position: absolute !important; width: 100% !important; height: 100% !important; left: 0; top: 0; border: 0 none; pointer-events: initial" title="HubSpot Video" loading="lazy" data-hsv-id="258939292374" data-hsv-style="" data-hsv-width="1918" data-hsv-height="908" data-hsv-autoplay="false" data-hsv-loop="false" data-hsv-muted="false" data-hsv-hidden-controls="false" data-hsv-full-width="false"></iframe>

 Put a # in front of the server to comment out that line, and deploy the code.

Now go to AWS \> EC2 and stop the instance you are looking to resize.

Check the box next to the instance, click on Instance State and select Stop Instance

![aws\_stop instance](https://help.imrchnt.com/hs-fs/hubfs/aws_stop%20instance.png?width=670&height=133&name=aws_stop%20instance.png)

Once the instance is stopped you can resize it under Actions \> Instance Settings \> Change Instance Type.

![aws\_change instance type](https://help.imrchnt.com/hs-fs/hubfs/aws_change%20instance%20type.png?width=670&height=220&name=aws_change%20instance%20type.png)

Within Change Instance Type is where you will set the Instance type.

![change instance type\_2](https://help.imrchnt.com/hs-fs/hubfs/change%20instance%20type_2.png?width=670&height=343&name=change%20instance%20type_2.png)

Enter the new instance type in the New instance type field (e.g. m3.xlarge).

Scroll down and click on Change Instance Type button.

![aws\_change instance type 3](https://help.imrchnt.com/hs-fs/hubfs/aws_change%20instance%20type%203.png?width=670&height=128&name=aws_change%20instance%20type%203.png)

Restart the Instance (Instance state \> Start Instance) and it will come back up as the new instance type. 

![aws\_start instance](https://help.imrchnt.com/hs-fs/hubfs/aws_start%20instance.png?width=670&height=243&name=aws_start%20instance.png)

Verify that the server has come back up properly by logging onto the server you've updated.

Final step is to go back into Lambda remove the # and deploy the change to enable the server to autostart when in a stopped state.
