What is Amazon EBS? How to Execute EBS in AWS? An Elastic Block Storage (EBS) Volume hosts virtual data in segments. It’s like a storage disk with the ability to contain various sizes of data. These virtual storage devices usually replicate within one AWS region to increase their availability. EBS volumes provide additional storage for EC2 instances, similar to a hard drive. Like physical hard disks, it’s critical to manage EBS volumes as they affect your AWS bill. Because of volatile cloud storage, EBS volumes provide a suitable alternative to permanent and robust storage.

AWS Elastic Block Store (EBS) is Amazon’s block-level storage solution used with the EC2 cloud service to store persistent data. This means that the data is kept on the AWS EBS servers even when the EC2 instances are shut down.

EBS offers the same high availability and low-latency performance within the selected availability zone, allowing users to scale storage capacity at low subscription-based pricing model. The data volumes can be dynamically attached, detached and scaled with any EC2 instance, just like a physical block storage drive. As a highly dependable cloud service, the EBS offering guarantees 99.999% availability.

AWS EBS is different from the standard EC2 Instance Store, which merely provides temporary storage available on the physical EC2 host servers. The EC2 Instance Store is useful for temporary data content such as caches, buffers or files that are replicated across the hosted servers. For data that needs to be available persistently, regardless of the operating life of an EC2 instance, the AWS EBS offers the following storage volume options:

  • General Purpose SSD (gp2): An optimum balance between cost and performance for a variety of IT workloads. Use cases include virtual desktops, apps, dev and test environments, among others.
  • Provisioned IOPS SSD (io1): The high-performance functionality serves particularly well for mission-critical IT workloads. Suitable use cases include large databases and business apps that require 16,000 IOPS or 250 MiB/s of throughput per volume.
  • Throughput Optimized HDD (st1): A low cost alternative for large storage volume workloads with high performance throughput requirements. Examples include streaming workloads, big data applications, log processing and data warehousing.
  • Cold HDD (sc1): An inexpensive alternative for use cases with a requirement to maintain minimal cost for large volume data storage. Examples include workloads that are accessed less frequently.

It’s important to note that each storage option doesn’t represent individual physical storage media, but a distributed system of storage options as per the categorized volume options. This AWS resource provides a detailed overview of the various EBS volume types.

What is AWS EBS in Amazon?

Let me explain what is AWS EBS in laymen terms with the help of an example. Suppose, you have a system with 120GB of storage. You run out of space and you need more space, so you get an external disk and attach it to your system. Life is good, you are happy again. The Amazon EBS is equivalent to that external disk, with the only difference that it is supposed to be used with your EC2 instances (virtual systems) on AWS cloud.

Now let’s understand what is AWS EBS Volume in technical terms.
Although Amazon does offer local storage for every EC2 Instance that you can use while you run the instance but as soon as the instance is shut down, the data in that local storage is also lost. Therefore, if you need to save the data, you would need Amazon EBS with your EC2 instance.

Since we have already understood what EBS is, in Laymen terms, let’s now focus on more technical definition of Amazon EBS.

AWS EBS is largely defined as a raw block level storage service, designed to be used with Amazon EC2 instances. Each block acts like a hard drive, where any type of file can be stored or even a whole operating system can be installed on it. Each EBS volume that you attach with your EC2 instance is automatically replicated within its availability zone to prevent data loss and component failure. With EBS, one can easily scale their usage up or down in a matter of few minutes.

The current generations of Amazon EBS offer four different types of volumes each with different characteristics which help to grow the business rapidly.

AWS EBS provides two types of volumes that are SSD-Backed delivering low-latency with highest IOPS and HDD-Backed for streaming sequential access for highest throughput.

SSD is best for the boot volumes and transactional workload which require low latency and high IOPS. Enterprises Applications, Relational Databases, and NoSQL Databases can all support the power of SSD-Backend.

HDD is best compatible for streaming IO and the highest throughput. Applications such as Big data Applications, Data Warehousing Applications, and Staging Applications will provide the cost one desires with the performance one needs.

In all cases, one can choose the volume type one needs. The User can connect different volume types to the EC2 instance. It is also compatible with the applications having different performance profiles.

The EBS provides maximum data protection as the failure rate is between 0.1 to 0.2%. The user can still take precautions by taking point-in-time snapshots for efficient backup, Archiving, and recovery for procuring new EC2 instances.

Create an EBS volume, choose a size, and then attach it to your EC2 instances to get started. An instance can have numerous volumes associated with it. However, an EBS system can only be attached to one instance simultaneously.

To offer the equivalent of a backup, you may take a snapshot of a volume, which records the data at a fixed time slot. Another volume you may attach to another instance can also be made using the snapshot.

If you change the snapshot permissions, you may make EBS snapshots accessible to the public or share them with a team member. EBS snapshots may also be copied to different AWS regions for disaster recovery and migration needs.
