Amazon Elastic Block Store: High-performance, user-friendly block storage at any size
What is Amazon EBS?
Amazon Elastic Block Store provides high-performance, scalable block storage with Amazon EC2 instances. AWS Elastic Block Store can create and manage several block storage resources:
Amazon EBS volumes: Amazon EC2 instances can use Amazon EBS volumes. A volume associated to an instance can be used to install software and store files like a local hard disk.
Amazon EBS snapshots: Amazon EBS snapshots are long-lasting backups of Amazon EBS volumes. You can snapshot Amazon EBS volumes to backup data. Afterwards, you can always restore new volumes from those snapshots.
Advantages of the Amazon Elastic Block Store
Quickly scale
For your most demanding, high-performance workloads, including mission-critical programs like Microsoft, SAP, and Oracle, scale quickly.
Outstanding performance
With high availability features like replication within Availability Zones (AZs) and io2 Block Express volumes’ 99.999% durability, you can guard against failures.
Optimize cost and storage
Decide which storage option best suits your workload. From economical dollar-per-GB to high performance with the best IOPS and throughput, volumes vary widely.
Safeguard
You may encrypt your block storage resources without having to create, manage, and safeguard your own key management system. Set locks on data backups and limit public access to prevent unwanted access to your data.
Easy data security
Amazon EBS Snapshots, a point-in-time copy that can be used to allow disaster recovery, move data across regions and accounts, and enhance backup compliance, can be used to protect block data storage both on-site and in the cloud. With its integration with Amazon Data Lifecycle Manager, AWS further streamlines snapshot lifecycle management by enabling you to establish policies that automate various processes, such as snapshot creation, deletion, retention, and sharing.
How it functions
A high-performance, scalable, and user-friendly block storage solution, Amazon Elastic Block Store was created for Amazon Elastic Compute Cloud (Amazon EC2).
Use cases
Create your cloud-based, I/O-intensive, mission-critical apps
Switch to the cloud for mid-range, on-premises storage area network (SAN) applications. Attach block storage that is both high-performance and high-availability for applications that are essential to the mission.
Utilize relational or NoSQL databases
Install and expand the databases of your choosing, such as Oracle, Microsoft SQL Server, PostgreSQL, MySQL, Cassandra, MongoDB, and SAP HANA.
Appropriately scale your big data analytics engines
Detach and reattach volumes effortlessly, and scale clusters for big data analytics engines like Hadoop and Spark with ease.
Features of Amazon EBS
It offers the following features:
Several volume kinds: Amazon EBS offers a variety of volume types that let you maximize storage efficiency and affordability for a wide range of uses. There are two main sorts of volume types: HDD-backed storage for workloads requiring high throughput and SSD-backed storage for transactional workloads.
Scalability: You can build Amazon EBS volumes with the performance and capacity requirements you want. You may adjust performance or dynamically expand capacity using Elastic Volumes operations as your needs change, all without any downtime.
Recovery and backup: Back up the data on your disks using Amazon EBS snapshots. Those snapshots can subsequently be used to transfer data between AWS accounts, AWS Regions, or Availability Zones or to restore volumes instantaneously.
Data protection: Encrypt your Amazon EBS volumes and snapshots using Amazon EBS encryption. To secure data-at-rest and data-in-transit between an instance and its connected volume and subsequent snapshots, encryption procedures are carried out on the servers that house Amazon EC2 instances.
Data availability and durability: io2 Block Express volumes have an annual failure rate of 0.001% and a durability of 99.999%. With a 0.1% to 0.2% yearly failure rate, other volume types offer endurance of 99.8% to 99.9%. To further guard against data loss due to a single component failure, volume data is automatically replicated across several servers in an Availability Zone.
Data archiving: EBS Snapshots Archive provides an affordable storage tier for storing full, point-in-time copies of EBS Snapshots, which you must maintain for a minimum of ninety days in order to comply with regulations. and regulatory purposes, or for upcoming project releases.
