amazon web services - What happens with data when I stop EBS backed instances -


what happens data in ephemeral storage when stop ebs backed instances?

  1. aws makes snapshot , store in ebs - not losing data
  2. aws makes snapshot , store in s3 - not losing data
  3. aws makes snapshot , store in ebs - losing data
  4. aws makes snapshot , store in s3 - losing data

when stop instance, data on ephemeral storage deleted. data on ebs volumes preserved exist independent of host.

ephemeral storage hard drive attached host machine. since instance not maintain affinity host when stopped, wont retain data.

ebs volumes network attached storage. exist in storage array outside of host , exist unless volume fails (which pretty rare)
