Cost of S3 Standard vs S3 Standard IA
This video compares the annual cost of S3 standard and S3 standard IA based on 3 separate use cases. This clearly shows why the object access pattern should be taken into consideration before deciding on your storage class. Storage cost is only a part of your S3 cost. Retrieval cost is too important to ignore. If you miss this point, you may end up incurring cost which may be 1000% more than what you would have paid otherwise.
S3 Standard is used for storing frequently accessed data. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored across S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA. You can use S3 Lifecycle policies to automatically transition objects between storage classes without any application changes.
S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. It has a low per GB storage price and per GB retrieval charge. This combination of low cost and high performance make S3 Standard-IA ideal for long-term storage, backups, and as a data store for disaster recovery files. S3 Storage Classes can be configured at the object level and a single bucket can contain objects stored across S3 Standard, S3 Intelligent-Tiering, S3 Standard-IA, and S3 One Zone-IA.
