1. EC2 Instance Store 개요

• EBS volumes are network drives with good but “limited” performance
• If you need a high-performance hardware disk, use EC2 Instance Store
• Better I/O performance
• EC2 Instance Store lose their storage if they’re stopped (ephemeral)
  • EC2 Instance Store는 장기적으로 데이터를 보관할 만한 장소가 될 수 없음 (장기적인 데이터 보관은 EBS를 사용)
• Good for buffer / cache / scratch data / temporary content
• Risk of data loss if hardware fails
• Backups and Replication are your responsibility
