AWS Instance Store

• Temporary storage for EC2 instances.
• Instance store gets storage from underlying physical disk.
• Size of instance store varies upon instance type.

Data in instance store is Lost if instance is stopped. So EC2 instances which are backed by Instance store type storage can’t be stopped and started again. AWS only allows to restart or terminate these type of instances.

• Data will not be lost if we reboot.
• If instance store is in use, then backs ups are recommended.
