Amazon provides a number of highly available, fault tolerant, and durable storage options we can take advantage of in our products. They span the range from block to object storage. Depending on your product needs, you can use them individually, or compose them as needed. Integration with compute, networking, and security services is a common practice. The mature APIs and instrumentation of the services simplify their use.
Elastic Block Storage (EBS) is the disk type you want to use for the majority of your products. EBS implements a standard block device for EC2 instances. Disks spawned by EBS can be cloned, extended, or attached to other instances. Snapshots can be taken while EBS volumes are in use to ensure Recovery Time Objectives (RTO) of data can be met.
