Understanding Amazon Elastic Block Store

In simple terms, Amazon EBS is a hard drive for a server in AWS. One advantage of Amazon EBS over many typical hard drives is that you can easily detach it from one server and attach it to another server using software commands. Normally, with other servers outside of AWS, this would require physically detaching the hard drive and physically attaching it to another server.

Additionally, if you use the Amazon EFS service, you will be able to attach the hard drive (block storage device) to multiple servers (EC2 instances). This greatly simplifies your maintenance and operations.

When using Amazon EBS, data is persisted. This means that data lives even after the server is shut down. Like with other services, Amazon EBS provides high availability and durability. Amazon provides a guarantee of 99.999% availability.

Amazon EBS should not be confused with the instance store that is available in EC2 instances. EC2 instance stores deliver ephemeral...
