What happens to the data stored in ephemeral storage when the EC2 instance is terminated?

The data is backed up automatically
The data is encrypted
The data is lost forever
The data is moved to EBS Volumes

The correct answer is: The data is lost forever

When an EC2 instance is terminated, any data stored in ephemeral storage is lost forever. Ephemeral storage, also known as instance store, is temporary storage that is directly attached to the physical server hosting the instance. It is designed for short-term use and is not persistent; once the instance terminates, the ephemeral storage is wiped clean, and any data residing there cannot be recovered. This makes ephemeral storage suitable for storing temporary files, caches, or data that can be regenerated, but it is not recommended for critical data that needs to be retained beyond the lifecycle of the instance. For persistent storage needs, users generally utilize Amazon Elastic Block Store (EBS) volumes or other AWS storage services that can preserve data independently of the EC2 instance's lifecycle.
