Therefore you don’t need to second-guess and pre-allocate disk space. You also only pay for the amount of storage you actually use. For one, Amazon can provide a highly durable storage service for the fraction of the cost of block storage. The abstraction away from the lower layers of storage and the separation of data from its metadata comes with a number of benefits. Unlike Amazon’s Elastic Block Store (EBS) or the local file system of your traditional PC, where data is managed in a directory hierarchy, Amazon S3 treats data as individual objects. So, what about Amazon S3 vs Amazon Glacier? Thanks to Amazon’s Simple Storage Service (S3) and its younger sibling, Amazon Glacier, you have the right services at hand to establish a cost-effective, yet practical backup solution. This can only be mitigated with an effective backup strategy. While you may have designed a highly resilient and durable solution, this won’t necessarily protect you from administrative mishaps, data corruption, or malicious attacks against your system. When you set out to design your first AWS (Amazon Web Services) hosted application, you will need to consider the possibility of data loss.
