aws ec2 instance nvme1n1 is howing 12gb not sure where it came from i dont have any ec2 instance running up

It appears there might be some confusion in your situation. If you don't have any EC2 instances running, you shouldn't be seeing any disk usage or device names like nvme1n1. This could indicate a few possibilities:

1. There might be a terminated instance that hasn't fully cleaned up its resources.
2. You might be looking at local storage on your own machine rather than an EC2 instance.
3. There could be a misconfiguration or error in the AWS console or CLI you're using.

To address this issue:

1. Double-check your AWS console to confirm no instances are running.
2. If you recently terminated an instance, wait a few minutes for all resources to be fully released.
3. Run 'aws ec2 describe-instances' in the AWS CLI to see if any instances are in a transitional state.

Regarding running a free Windows Server on AWS:

AWS offers a Free Tier that includes 750 hours per month of t2.micro instances running Microsoft Windows Server. This is available for 12 months for new AWS accounts. To use this:

1. Create an AWS account if you haven't already.
2. Launch a t2.micro instance with a Windows Server AMI.
3. Make sure to stay within the Free Tier limits to avoid charges.

Remember, while the instance hours are free, you may still incur charges for other resources like storage or data transfer beyond the free tier limits. Always monitor your usage to avoid unexpected costs.

If you're having trouble launching a Windows Server instance, make sure you have sufficient permissions and that you're following the correct steps in the EC2 launch wizard. If issues persist, you may need to contact AWS support for further assistance.

Hi,

You're seeing here the storage used by the EC2 instance running under the CloudShell terminal that you are using to run your command.

I did same thing my side and I get exactly same result as you do:

[cloudshell-user@ip-10-130-63-14 ~]$ df -h

Best,

You're running this command in AWS CloudShell, which under the hood is just a Linux host. As such, it needs things like CPU, memory, disk and network to run, and the output of df -h shows the 16GB disk that this CloudShell instance is using (look at the Size column not the Avail column).

You won't see this as an EBS volume in the AWS Console because you don't manage the CloudShell service, AWS does.

You won't be charged for it https://aws.amazon.com/cloudshell/pricing/

Basically, the storage you can see here is nothing to do with any storage that you may have provisioned for use with EC2 instances.

My answer is I connected amazon +stripe it's an easy for you to use for open stot and selling
