Amazon EBS [Elastic Block Store]
About Amazon EBS [Elastic Block Store]
For use with Amazon Elastic Compute Cloud, Amazon Elastic Block Store (Amazon EBS) is a high-performance, scalable, and user-friendly block-storage solution (Amazon EC2).
You can consolidate and automate data protection for all AWS services with AWS Backup. The cost-effective, fully managed, policy-based solution provided by AWS Backup makes data protection at scale simple. AWS Backup enables you to accomplish your objectives for business continuity while supporting your duties for regulatory compliance.
Why is Amazon EBS [Elastic Block Store] important?
- Move mid-range SAN (storage area network) workloads from on-premises to the cloud. Attach block storage with high performance and availability for mission-critical applications.
- Your preferred databases, such as SAP HANA, Oracle, Microsoft SQL Server, MySQL, Cassandra, and MongoDB, can be deployed and scaled.
- Detach and reattach volumes at will, and easily scale clusters for big data analytics engines like Hadoop and Spark.

Certificate in Amazon EBS [Elastic Block Store] FAQs
What is Amazon EBS used for?
Amazon EBS provides block-level storage for EC2 instances, suitable for use cases like databases, log processing, and application data storage.
How are EBS volumes different from S3?
EBS provides persistent block storage for running EC2 instances, while S3 is object storage designed for scalable data archiving and retrieval.
Can I move EBS volumes between regions?
Not directly, but you can copy snapshots across regions and create new volumes from those snapshots.
What is the difference between gp2 and gp3?
gp3 offers better baseline performance and allows independent scaling of IOPS and throughput, unlike gp2.
How does EBS encryption work?
EBS supports encryption using AWS KMS, which ensures that all data at rest, in transit, and in snapshots is encrypted.
Can I use a snapshot to create a new volume in a different AZ?
Yes, snapshots can be used to launch new volumes in any Availability Zone within the same region.
What happens if an EBS volume fails?
AWS automatically replicates volumes within an AZ for durability. You can restore from a snapshot if needed.
How do I monitor EBS performance?
Use Amazon CloudWatch to track IOPS, throughput, and latency metrics.
Is data deleted when I terminate an EC2 instance?
Yes, if the EBS volume is marked for deletion on termination. You can modify this setting to retain volumes.
Is EBS included in the AWS Free Tier?
Yes, AWS Free Tier offers limited EBS usage, including 30 GB of storage and 2 million I/Os per month.
