Introduction to Amazon Elastic Block Store (EBS)

Amazon EBS is an Elastic Block Storage is a block level storage volumes for the Amazon EC2 instances in the Amazon Cloud. In the simple words EBS can be described as extra volumes that can be attached and detached from the EC2 instance. Each Amazon EBS volume is replicated automatically within the availability zone to prevent from component failure and offering high performance.

In my post

  1. i will create a new volume 
  2. attach the volume to created EC2
  3. Create a Snapshot

Creating the volume is an easy step 

goto EC2>Volumes>Create Volume

in Create Volume i had given the volume details

Type: General Purpose

Size: 1GB

Availability: US West-2b

I added my created volume to EC2 instance that was already exist in my cloud.Its a simple steps firstly we need to detach the volume which is already paired to the Ec2 instance then attach the volume that you had created.

 As we require more snapshots while we working a project. EBS is flexible in creating the snapshots for a instance. In Amazon EBS snapshots are used to change the properties of the volume to enable the features like provisioned IOPS

For creating a snapshot just goto EC2>Snapshots>Create

Once the snapshot is created we can attach to the EC2 instance which i showed you earlier.

Firstly detach the volume that instance had

add the snapshot volume to the instance

Well you attached the volume that contains all the data from the original drive.

Yes!!! we successfully created the snapshots and attached the volumes to the instances.
