Amazon EBS Tutorial

1. Introduction

Amazon Elastic Block Store (EBS) is a cloud block storage service designed for use with Amazon EC2. It provides highly available and durable storage volumes that can be attached to EC2 instances. EBS is essential for applications requiring a database, file system, or access to raw block-level storage. It matters because it ensures data persistence even when instances are terminated, making it a crucial part of cloud architectures.

2. Amazon EBS Services or Components

Amazon EBS includes several key components:

• Standard Volumes: General-purpose SSD and magnetic storage options.
• Provisioned IOPS SSD: Designed for I/O-intensive applications.
• Snapshots: Point-in-time backups of your EBS volumes.
• Encryption: Data-at-rest and data-in-transit encryption capabilities.

3. Detailed Step-by-step Instructions

To create and attach an EBS volume to your EC2 instance, follow these steps:

aws ec2 create-volume --size 10 --availability-zone us-east-1a --volume-type gp2

aws ec2 attach-volume --volume-id vol-0abcd1234efgh5678 --instance-id i-0abcd1234efgh5678 --device /dev/sdf
