This table illustrates the significant differences between Amazon S3 and Amazon EBS. Amazon EBS volumes are network-attached hard drives that can be written to or read from at a block level. Amazon S3 is an object-level storage medium. This means that you must write whole objects at a time. If you change one small part of a file, you must still rewrite the entire file in order to commit the change to Amazon S3. This can be very time-consuming if you have frequent writes to the same object. Amazon S3 is optimized for write-once/read-many use cases. The other major difference is cost. With Amazon S3 you pay for what you use, and with Amazon EBS you pay for what you provision.

An instance store provides temporary block-level storage for your instance. This storage is located on disks that are physically attached to the host computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, or for data that is replicated across a fleet of instances, such as a load-balanced pool of web servers.

Use the local instance store only for temporary data. For data that requires a higher level of durability, use Amazon EBS volumes or back up the data to Amazon S3. If you are using an Amazon EBS volume as a root partition and want your Amazon EBS volume to persist outside of the life of the instance, set the Delete on termination flag to “No”.
