Introduction to EC2 Storage-
Amazon EC2 provides you with flexible, cost-effective, and easy-to-use data storage options for your instances. EC2 basically provides two types of block-level storage. Instances can either be launched with Elastic block storage volume (EBS volume) or Instance store-backed volumes as to their root volumes. Each option has a unique combination of performance and durability. But Aws recommends using EBS storage-backed AMIS as they get launched faster and provide persistent storage.
