# Elastic Block Storage (EBS)
#cloud #aws #storage
A device access block storage solution by AWS.
Highly available and durable solution for attaching persistent block storage volumes to an EC2 instance. Volumes are automatically replicated within their Availability Zone (AZ) to protect from component failure. Currently most types of EBS do not store multi-attach (Except io1 Provisioned IPOS volume on Nitro based systems).
EBS multi-Attach
You can use a provisioned IOPS io1 volume that could be accessed by Nitro system based
EC2 upto 16 instances.
# EBS Volume Types
1. SSD-Backed Volumes
2. HDD-Backed Volumes
Summary:
# Moving EBS Volumes and Operations
# From one AZ to another
- Take a snapshot
- create an AMI from the snapshot
- launch an EC2 instance
# From one Region to another
- Take a snapshot
- create an AMI from the snapshot
- Copy the AMI from one region to another
- launch an EC2 instance
# EBS - Encrypted Root Volume
You can enable
Encryption on the root volume
# EBS Operations Summary
A EBS volume could be recreated through a snapshot. An Snapshot is alco created while you create a AMI. You can also create a AMI from a snapshot. It is discussed in detail on the slides.
