Elastic Block Storage


Amazon Elastic Block Storage (Amazon EBS) is a durable block storage volume that can be used with EC2 instances. EBS offers reliable high performance that enables the applications to run efficiently. We can scale the EBS volume up and down within minutes by paying a low price for the volume we use. EBS handles fault tolerance by replicating the volume in availability zones. EBS also provides the option to take a snapshot of the EBS volume which can be stored on Amazon S3 periodically. This snapshot can be used as a baseline for new volume or can be used for backup and restore purposes. EBS offers a wide range of volumes which are efficient in different use cases. We can choose wisely which type of EBS volume is suitable for our application or software. The following are the volume types:

  • General Purpose SSD (gp2)
  • Provisioned IOPS SSD (io1)
  • Throughput Optimized HDD (st1)
  • Cold HDD (sc1)
  • Magnetic (standard)
