What is Amazon instance store?

Publish date: 2023-07-11
An AWS instance store is a temporary storage type located on disks that are physically attached to a host machine. Instance stores are made up of single or multiple instance store volumes exposed as block devices. Block storage on AWS is available with AWS EBS. Once an instance is terminated, all of its data is lost.

Also asked, what is the difference between instance store and EBS?

TL;DR. EBS volume is network attached drive which results in slow performance but data is persistent meaning even if you reboot the instance data will be there. Instance store is physically attached device which gives better performance but data will be lost once instance is rebooted.

Similarly, what happens to data stored on an instance store volume when an ec2 instance is stopped or terminated? According to the documentation, "By default, the root device volume and the other Amazon EBS volumes attached when you launch an Amazon EBS-backed instance are automatically deleted when the instance terminates" but you can modify that via configuration.

EBS starts out really simple. You create a volume from 1GB to 1TB in size and then you mount it on a device (such as /dev/sdj) on an instance, format it, and off you go. Later you can detach it, let it sit for a while, and then reattach it to a different instance.
