Amazon Elastic Block Store
Easy to use, high performance block storage at any scale
What is Amazon EBS?
Amazon EBS allows you to create storage volumes and attach them to Amazon EC2 instances. Once attached, you can create a file system on top of these volumes, run a database, or use them just like you would use block storage. Amazon EBS volumes are placed in a specific Availability Zone, where they are automatically replicated to protect from the failure of a single component. All EBS volume types offer durable snapshot capabilities and are designed for high availability.
