EBS Storage

The data stored on a local instance store will persist only as long as that instance is alive. However, data that is stored on an Amazon EBS volume will persist independently of the life of the instance. Therefore, we recommend that you use the local instance store for temporary data and, for data requiring a higher level of durability, we recommend using Amazon EBS volumes or backing up the data to Amazon S3. If you are using an Amazon EBS volume as a root partition, you will need to set the Delete On Terminate flag to "N" if you want your Amazon EBS volume to persist outside the life of the instance.

Amazon EBS provides two volume types: Standard Volumes and Provisioned IOPS Volumes. They differ in performance characteristics and price, allowing you to tailor your storage performance and cost to the needs of your applications.

Standard volumes offer storage for applications with moderate or bursty I/O requirements.

These volumes deliver approximately 100 IOPS on average with a best effort ability to burst up to hundreds of IOPS. Standard volumes are also well suited for use as boot volumes, where the burst capability provides fast instance start-up times. Provisioned IOPS volumes are designed to deliver predictable, high performance for I/O intensive, random read and write workloads such as databases. With Provisioned IOPS, you specify an IOPS rate when creating a volume, and then Amazon EBS provisions that rate for the lifetime of the volume.

Amazon EBS currently supports up to 4000 IOPS per Provisioned IOPS volume.

You can stripe multiple volumes together to deliver thousands of IOPS per Amazon EC2 instance to your application.

Unlike the data stored on a local instance store (which persists only as long as that instance is alive), data stored on an Amazon EBS volume can persist independently of the life of the instance. Therefore, we recommend that you use the local instance store only for temporary data. For data requiring a higher level of durability, we recommend using Amazon EBS volumes or backing up the data to Amazon S3. If you are using an Amazon EBS volume as a root partition, set the Delete on termination flag to "No" if you want your Amazon EBS volume to persist outside the life of the instance.
