Amazon EBS

Amazon Elastic Block Store (Amazon EBS) provides persistent block level storage volumes for use with Amazon EC2 instances in the AWS Cloud. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. Amazon EBS volumes offer the consistent and low-latency performance needed to run your workloads. With Amazon EBS, you can scale your usage up or down within minutes – all while paying a low price for only what you provision.


  • Reliable, secure storage
    Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure. Amazon EBS encryption provides seamless support for data at rest security and data in motion security between EC2 instances and EBS volumes. Amazon's flexible access control policies allow you to specify who can access which EBS volumes.
  • Consistent and low-latency performance
    Amazon EBS General Purpose (SSD) volumes and Amazon EBS Provisioned IOPS (SSD) volumes deliver low-latency through SSD technology and consistent I/O performance scaled to the needs of your application. Stripe multiple volumes together to achieve even higher I/O performance.
  • Backup, restore, innovate
    Backup your data by taking point-in-time snapshots of your Amazon EBS volumes. Boost the agility of your business by using Amazon EBS snapshots to create new EC2 instances.
  • Quickly scale up, easily scale down
    Increase or decrease block storage and performance within minutes, enjoying the freedom to adjust as your needs evolve. Commission thousands of volumes simultaneously.
  • Geographic flexibility
    Amazon EBS provides the ability to copy snapshots across AWS regions, enabling geographical expansion, data center migration, and disaster recovery.

Use Cases

  • Relational databases
    Amazon EBS scales with your performance needs, whether you are supporting millions of gaming customers or billions of e-commerce transactions. Databases such as Oracle, Microsoft SQL Server, MySQL and PostgreSQL are widely deployed on Amazon EBS.
  • Enterprise applications
    Amazon EBS meets the diverse needs of your organization by providing reliable block storage to run mission-critical applications such as Oracle, SAP, Microsoft Exchange and Microsoft SharePoint.
  • File workloads
    Create file systems on Amazon EBS to store your files and applications securely and to support distributed file sharing.
  • Development & test environments
    Amazon EBS enables your organization to be more agile and responsive to customer needs. Provision, duplicate, scale, or archive your development, test and production environments with a few clicks.
  • NoSQL databases
    If you want to leverage Amazon EC2's on-demand compute capacity for additional capacity during peak periods, for new projects, or as a more cost-effective way to run your normal workloads, you can use the AWS Storage Gateway to mirror your volume data to Amazon EC2 instances.
  • Business continuity
    Minimize data loss and recovery time by regularly backing up your data and log files across different geographic regions. Copy Amazon Machine Images (AMIs) and EBS Snapshots to launch applications in new AWS regions.
