Amazon RDS for SQL Server Pricing

On-Demand DB Instances let you pay for compute capacity by the hour your DB Instance runs with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs. 

For both Single-AZ and Multi-AZ deployments, pricing is per DB instance-hour consumed from the time a DB instance is launched until it is stopped or deleted. Partial DB instance-hours are billed in one-second increments with a 10 minute minimum charge following a billable status change, such as creating, starting, or modifying the DB instance class.

T3 CPU Credits

Amazon RDS T3 DB instances run in Unlimited mode, which means that you will be charged if your average CPU utilization over a rolling 24-hour period exceeds the baseline of the instance. CPU Credits are charged at $0.144 per vCPU-Hour. The CPU Credit pricing is the same for all T3 instance sizes across all regions and is not covered by Reserved Instances.

Amazon RDS Reserved Instances give you the option to reserve a DB instance for a one or three year term and in turn receive a significant discount compared to the On-Demand Instance pricing for the DB instance. Amazon RDS provides three RI payment options -- No Upfront, Partial Upfront, All Upfront -- that enable you to balance the amount you pay upfront with your effective hourly price.

Single-AZ DB Reserved Instances can be applied to a database instance in a single Availability Zone. Multi-AZ deployments have separate reservation options.

Please note that Reserved Instance prices don't cover storage or I/O costs. To learn more about features, payment options, and rules, please visit our Reserved Instances page.

You may designate database instances as Reserved Instances by calling to the Purchasing API or selecting the Reserved Instance option in the AWS console. When you designate a database instance as a Reserved Instance, you must designate a region, instance type, and quantity for the applicable Reserved Instances. The Reserved Instances may only be used in the designated region. We may terminate the Reserved Instance pricing program at any time. In addition to being subject to Reserved Instance pricing, Reserved Instances are subject to all data transfer and other fees applicable under the AWS Customer Agreement or other agreement with us governing your use of our services.

For each DB Instance class, Amazon RDS provides you the ability to select up to 16 TB of associated storage capacity for your primary data set.

Amazon RDS provides you the ability to select from 20 GiB to 16 TiB of associated General Purpose (SSD) storage capacity for your primary data set. 

Provisioned IOPS volumes are designed to meet the needs of your most I/O intensive workloads, particularly database workloads that require low I/O latency and consistent I/O throughput. With provisioned IOPS volumes, you can scale from 1000 IOPS – 256,000 IOPS and 100 GiB to 64 TiB of storage. You will be charged for the IOPS and storage you provision. Note that maximum realized IOPS will vary by database workload.

Amazon RDS provides you the ability to select from 20 GiB to 3 TiB of associated Magnetic Storage capacity for your primary data set. Magnetic storage is supported for backward compatibility. We recommend that you use General Purpose SSD or Provisioned IOPS SSD for any new storage needs.

The pricing below is based on data transferred “in” and “out” of Amazon RDS.

• Data transferred between Amazon RDS and Amazon EC2 Instances in the same Availability Zone is free.
• Data transferred between Availability Zones for replication of Multi-AZ deployments is free.
• Amazon RDS DB Instances outside VPC: For data transferred between an Amazon EC2 instance and Amazon RDS DB Instance in different Availability Zones of the same Region, there is no Data Transfer charge for traffic in or out of the Amazon RDS DB Instance. You are only charged for the Data Transfer in or out of the Amazon EC2 instance, and standard Amazon EC2 Regional Data Transfer charges apply ($.01 per GB in/out).
• Amazon RDS DB Instances inside VPC: For data transferred between an Amazon EC2 instance and Amazon RDS DB Instance in different Availability Zones of the same Region, Amazon EC2 Regional Data Transfer charges apply on both sides of transfer.
• DB Snapshot Copy is charged for the data transferred to copy the snapshot data across regions. Once the snapshot is copied, standard database snapshot charges will apply to store it in the destination region.
• Cross Region Automated Backups is charged for the data transferred to copy the DB snapshot and DB transaction logs across regions. Once the snapshot is copied, standard database snapshot charges will apply to store it in the destination region. There is no additional charge for storage of the DB transaction logs.
• As part of AWS’s Free Usage Tier, AWS customers receive 100 GB of free data transfer out to the internet free each month, aggregated across all AWS Services and Regions (except China and GovCloud).
• Rate tiers take into account your aggregate Data Transfer Out usage across Amazon EC2, Amazon EBS, Amazon S3, Amazon Glacier, Amazon RDS, Amazon SimpleDB, Amazon SQS, Amazon SNS, AWS Storage Gateway, Amazon DynamoDB, and Amazon VPC.
