How is Amazon S3 Priced?
Amazon Simple Storage Service (Amazon S3) is an elastically scalable object storage service. The service provides a free tier to get you started, with limited capacity for 12 months.
Beyond the limits of the free tier, S3 storage pricing has five components:
1. Storage tiers - S3 prices per GB-month of storage, and pricing varies according to the storage tier you select. The S3 Standard tier provides instant access with low data retrieval costs, but a relatively high cost per GB. There are lower cost tiers that offer lower cost per GB, but higher cost of data retrieval or delayed data retrieval.
2. Cost per requests - S3 has a cost per 1,000 requests, depending on the request type.
3. Data transfer - there are extra charges for data transfer from S3 to the Internet, or certain AWS regions.
4. Management and analytics - S3 charges extra for automating the data lifecycle and moving data automatically to the most optimal storage tiers.
5. Replication - if you set up replication in S3, data transfer and operations performed during replication are charged like regular S3 operations.
