Introduction

Amazon Elastic Block Store is a block storage service designed to store continuous data. It is an easy-to-use and scalable service designed especially for Amazon Elastic Compute Cloud. It provides the choice to choose the storage volume that best suits your workload. It has three types of volume, namely General Purpose(SSD), Provisioned IOPS(SSD), and Magnetic, distinguished on the basis of cost and performance. Let's discuss them one by one.

Amazon Elastic Block Store

General Purpose(SSD)

It is an easy to use, lower cost - higher performance volume type suitable for small and medium workloads like frequently logs accessing workloads, small and medium workloads, etc. Its storage capacity ranges from 1GB to 1TB. It supports 3 Input Output Operations Per Second/GB. It costs $0.10 per GB per volume for one month.

Provisioned IOPS

It is highly durable, low latent, and highly performable, along with a multi-attach support volume type suitable for large relational, transactional, and intensive workloads. Its storage capacity ranges from 10 GB to 1 TB. It supports 30 Input Output Operations Per Second/GB. It costs $0.125 per GB per volume for provisioned storage.

Magnetic Volumes

This type of volume is suitable for workloads like data backups for recovery, logs storage, etc. Its storage capacity ranges from 10GB to 1TB. It costs $0.05 per GB per Volume for one month for provisioned storage.

Features of Amazon EBS

Secure

Amazon EBS provides a simple encryption solution that lets you specify who can access which EBS volumes. This feature makes EBS a useful service.

Higher Performance

Amazon EBS uses SSD to deliver results that enhance the performance of EBS.

Reliable

Each EBS volume responds to its availability zone to protect from component failure.This makes the whole system reliable.

Amazon EBS Benefits

Reliable and secure storage − Each of the EBS volume will automatically respond to its Availability Zone to protect from component failure.
Secure − Amazon’s flexible access control policies allows to specify who can access which EBS volumes. Access control plus encryption offers a strong defense-in-depth security strategy for data.
Higher performance − Amazon EBS uses SSD technology to deliver data results with consistent I/O performance of application.
Easy data backup − Data backup can be saved by taking point-in-time snapshots of Amazon EBS volumes.

Frequently Asked Questions

How do I modify the capacity and type of an existing EBS volume?

Volume can be easily changed in EBS. EBS allows you to increase capacity, tune performance, or change your volume type with a single CLI call, API call or a few console clicks.

How can I discover Amazon EBS snapshots that are shared with me?

You can find snapshots that are shared with you by selecting Private Snapshots from the list in the Snapshots section of the AWS Management Console. This section lists both snapshots that you own and snapshots that are shared with you.

What is Amazon EBS encryption?

Amazon EBS encryption offers seamless encryption of EBS data volumes, boot volumes and snapshots, eliminating the need to build and maintain a secure key management infrastructure.
