cPanel on AWS - data retention

[osvi]

Hello,
I wonder how does it work cPanel over AWS, using the official supported AMI.

Since EC2 disks are volatile, is cPanel resetted if I stop and restart a server?
Is it possible to change instance type after the installation (for more CPU/RAM)?

Thank you!

Hi @osvi

You can read our documentation on Amazon AWS Instances here: Amazon AWS Guide - cPanel Knowledge Base - cPanel Documentation

Please let us know if you have further questions once going through the guide.

Thanks!

Hi Lauren,
from the documentation it is not clear where the data is stored, nor if it is possible to migrate between instance types.

Thank you!

Hello @osvi,

Good questions!

1. As you can see in the image below, "Shutdown Behavior" is set to "Stop" instead of "Terminate" by default when setting up the AMI:



Thus, stopping or rebooting the server should not terminate the instance or result in data loss unless you configure "Terminate" as the shutdown behavior.

2. Changing the instance type is known as resizing. Amazon documents how this works at:

Changing the Instance Type - Amazon Elastic Compute Cloud

Once you stop the instance, you can then change the instance type as seen in the image below:



Note the Amazon link above documents multiple considerations to be aware of before performing this action.

Let me know if you need me to perform any tests or clarify any additional behavior.

Thank you.
