According to Best practices for configuring network interfaces guide, there are three ways to attach a network interface to an instance:
You can attach a network interface to an instance when:
- it's running (hot attach),
- when it's stopped (warm attach), or
- when the instance is being launched (cold attach).
However, the only places where these terms are mentioned is the AWS documentation page linked above, some SAA-C03 practice exam questions at Cloud Guru and exam notes published at personal blogs.
Are these terms really a thing?
If so, using the word "warm" for attaching to a stopped instance and "cold" for one being launched seems to be counter-intuitive. Why such a choice of words?
