Is NVME ephemeral?

It’s ephemeral, yes. It survives reboots, so that’s not a problem. It doesn’t survive instance-stop, so if a machine is being decommissioned by AWS we do indeed lose its data.

Is emptyDir ephemeral storage?

What is Amazon EC2 in AWS DevOps?

To get a better idea of what’s involved in implementing DevOps on AWS, we need to break down the system’s underlying architecture, using AWS EC2 as our example. EC2 stands for Elastic Compute Cloud, which lets users configure virtual machines and the underlying resources they leverage from a central console.
