Amazon EC2 instance RAM
Instance Store
Amazon Elastic Block Store (EBS)
AWS Lambda temporary storage

Correct Incorrect Unanswered

Report Issue

Answer Description

Amazon Elastic Block Store (EBS) provides persistent block storage volumes for use with Amazon EC2 instances. EBS volumes are network-attached, and they persist independently from the life of an instance. This means that the data on EBS volumes will survive even if the EC2 instance is stopped, terminated, or rebooted. On the other hand, instance store volumes are ephemeral and the data is lost if the EC2 instance is stopped or terminated.
