Amazon Simple Storage Service (Amazon S3) - How AWS Pricing Works
Estimating Amazon S3 storage costs

Amazon Simple Storage Service (Amazon S3)

Amazon S3 is object storage built to store and retrieve any amount of data from anywhere: websites, mobile apps, corporate applications, and data from Internet of Things (IoT) sensors or devices. It is designed to deliver 99.999999999 percent durability, and stores data for millions of applications used by market leaders in every industry. As with other AWS services, Amazon S3 provides the simplicity and cost-effectiveness of pay-as-you-go pricing.

Estimating Amazon S3 storage costs

With Amazon S3, you pay only for the storage you use, with no minimum fee. Prices are based on the region of your Amazon S3 bucket. When you begin to estimate the cost of Amazon S3, consider the following:

  • Storage class: Amazon S3 offers a range of storage classes designed for different use cases. These include S3 Standard for general-purpose storage of frequently accessed data; S3 Intelligent-Tiering for data with unknown or changing access patterns; S3 Standard-Infrequent Access (S3 Standard-IA); S3 One Zone-Infrequent Access (S3 One Zone-IA) for long-lived, but less-frequently accessed data; Amazon S3 Glacier Instant Retrieval (S3 Glacier Instant Retrieval) for long-lived data that is rarely-accessed and requires milliseconds retrieval; Amazon S3 Glacier Flexible Retrieval (S3 Glacier Flexible Retrieval); Amazon S3 Glacier Deep Archive (S3 Glacier Deep Archive) for long-term archive and digital preservation. Amazon S3 also offers capabilities to manage your data throughout its lifecycle. Once an S3 Lifecycle policy is set, your data will automatically transfer to a different storage class without any changes to your application.

  • Storage: Costs vary with number and size of objects stored in your Amazon S3 buckets as well as type of storage.

  • Requests and data retrievals: Requests costs made against S3 buckets and objects are based on request type and quantity of requests.

  • Data transfer: The amount of data transferred out of the Amazon S3 region. Transfers between S3 buckets or from Amazon S3 to any service(s) within the same AWS Region are free.

  • Management and replication: You pay for the storage management features (Amazon S3 inventory, analytics, and object tagging) that are enabled on your account’s buckets.
