EC2 Instance Store

EBS volumes are network drives with good but "limited" performace

 

SO if you need a high-performace hardware disk, use EC2 Instance Store.

its a named of a hardware which is attacted to physical server.

 

- Gives better I/O performance

- great choice on a high performace 

- Good for buffer / Cache / Scratch data / temporary content 

// not good for long term storage

 

However it loses storage when EC2 is stopped/termiated. (ephemeral)

- Risk of data loss if hardware fails

( So its our responsibility to back up data).
