On-Demand DB Instances costs

On-Demand database (DB) Instances allow you to pay for compute capacity per hour your database instance runs with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms 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.
  • For partial DB instance-hours, they are billed in one-second increments with a 10-minute minimum charge after a billable status change, like creating, starting, or modifying the DB instance class.

T4g and T3 CPU Credits

Amazon RDS for MariaDB T4g and T3 DB instances run in Unlimited mode, meaning you will be charged if your average central processing unit (CPU) utilization over a rolling 24-hour period surpasses the instance baseline. CPU credits are charged at $0.075 per vCPU-hour. The CPU credit pricing is the same across all Regions, for all T4g and T3 instance sizes, and is not covered by Reserved Instances.

Reserved Instances costs

Amazon RDS Reserved Instances (RI) provide you the option to reserve a DB instance for a one- or three-year term, which gives you a significant discount compared to the On-Demand Instance pricing. Amazon RDS provides three RI payment options—No Upfront, Partial Upfront, and All Upfront—which allow you to balance the amount of your upfront payment with your effective hourly price.

Reserved Instances provide size flexibility for the MariaDB database engine. Your RI’s discounted rate automatically applies to usage of any size in the same instance family (M5, T3, R5, etc.) with size flexibility.

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

You may designate database instances as Reserved Instance by calling to the Purchasing API or selecting the Reserved Instance option in the AWS console. When designating your DB instance as a Reserved Instance, you’re required to designate an instance type, Region, and quantity for the applicable Reserved Instances. You may only use the Reserved Instances in the designated Region.

AWS may terminate the Reserved Instance pricing program at any time. As well as being subject to Reserved Instance pricing, Reserved Instances are subject to all other fees applicable under the AWS Customer Agreement, including data transfer fees, or other agreements with AWS governing your usage of AWS services.

    • Single-AZ Deployment

    • Calculation of RI monthly fees

      * This is the average monthly payment over the course of the Reserved Instance term. For each month, the actual monthly payment will either equal the actual number of hours in that month multiplied by the hourly usage rate or the number of seconds used in that month multiplied by the hourly usage rate, divided by 3600. The formula you use will depend on the Amazon RDS for MariaDB instance type you run.

      The hourly usage rate is equivalent to the total average monthly payments over the term of the Reserved Instance divided by the total number of hours (based on a 365-day year) over the term of the Reserved Instance.

      Calculation of RI effective hourly rate

      ** Effective hourly pricing helps you calculate the amount of money a Reserved Instance will save you over On-Demand pricing.

      When you purchase a Reserved Instance, you are billed for every hour during the entire Reserved Instance term you select, regardless of whether the instance is running. The effective hourly price shows the amortized hourly instance cost. This takes the total cost of the Reserved Instance over the entire term, including any upfront payment, and spreads it out over each hour of the Reserved Instance term.

    • Multi-AZ Deployment

    • Calculation of RI monthly fees

      * This is the average monthly payment over the course of the Reserved Instance term. For each month, the actual monthly payment will either equal the actual number of hours in that month multiplied by the hourly usage rate or the number of seconds used in that month multiplied by the hourly usage rate, divided by 3600. The formula you use will depend on the Amazon RDS for MariaDB instance type you run.

      The hourly usage rate is equivalent to the total average monthly payments over the term of the Reserved Instance divided by the total number of hours (based on a 365-day year) over the term of the Reserved Instance.

      Calculation of RI effective hourly rate

      ** Effective hourly pricing helps you calculate the amount of money a Reserved Instance will save you over On-Demand pricing.

      When you purchase a Reserved Instance, you are billed for every hour during the entire Reserved Instance term you select, regardless of whether the instance is running. The effective hourly price shows the amortized hourly instance cost. This takes the total cost of the Reserved Instance over the entire term, including any upfront payment, and spreads it out over each hour of the Reserved Instance term.

Database storage costs

Dedicated Log Volume costs

A Dedicated Log Volume is an additional storage volume specifically for database redo logs and binlogs that is separate from the volume containing the database tables, making transaction write logging more efficient and consistent. A Dedicated Log Volume is ideal for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency sensitive workloads.

Dedicated Log Volumes are priced the same as a data volume with 1,000 GiB and 3,000 IOPS and by storage type. Dedicated Log Volumes are only supported in Provisioned IOPS storage. For example, in US East (N. Virginia), an io1 Dedicated Log Volume attached to a Single-AZ instance in RDS for MariaDB would cost $0.125 x 1024 GiB plus $0.10 x 3000 IOPS, or $428/month. If you were to run an io1 Dedicated Volume in the same AWS Region attached to Multi-AZ with one standby, it would cost you $0.25 x 1024 GiB plus $0.20 x 3000 IOPS, or $856/month.

To learn more about data volume pricing, see the Provisioned IOPS SSD storage costs section above.

Backup storage costs

Snapshot export costs

Amazon RDS snapshot export provides an automated method to export data within an Amazon RDS for MariaDB snapshot to Amazon S3 in Parquet format. The Parquet format consumes up to 6x less storage in Amazon S3 compared to text formats and is up to 2x faster to unload. You can analyze the exported data using AWS services, such as Amazon SageMaker, Amazon Athena, and Amazon EMR.

Snapshot export pricing example

For example, suppose you have a 100 GB snapshot and you use filtering to select a 10 GB table from this snapshot to export to Amazon S3. To export this data, you would pay 100 GB * $0.013 per GB of snapshot size. Subsequent exports of data from the same snapshot are not incremental.

Additional charges apply for encrypting or decrypting data with AWS Key Management Service. Find more about these charges on the AWS KMS pricing page. Charges also apply for storing exported data in Amazon S3 and for PUT requests made against your S3 bucket. Find more about these charges on the Amazon S3 pricing page.

Data transfer costs

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

When launching your Amazon RDS for MariaDB instance, use the same instance type and Region for which you made the reservation. Amazon RDS for MariaDB will apply the reduced hourly rate for which you are eligible to the new DB instance so long as your reservation purchase is active. 

How many Reserved Instances can I purchase?

You can purchase up to 40 Reserved Instances. If you wish to run more than 40 DB instances, please complete the Amazon RDS DB Instance request form.

How do the Reserved Instance payment options impact my Amazon RDS for MariaDB bill?

There is no difference between Reserved Instances (RIs) and On-Demand Instances when creating, modifying, and deleting an Amazon RDS for MariaDB instance. The AWS system automatically applies your reservation(s) when computing your bill, such that all eligible Amazon RDS for MariaDB DB instances are charged at the lower hourly Reserved DB Instance rate.

  • All-Upfront option: You pay for the entire term of the RI in one upfront payment when purchasing a RI under the All-Upfront payment option.
  • No Upfront option: When you choose the No Upfront option, you can choose to pay nothing upfront. The entire value of the No Upfront RI is spread across every hour in the term and, regardless of usage, you will be billed for every hour in the term.
  • Partial upfront option: This is a hybrid of the All Upfront and No Upfront options. You make a small upfront payment. You are then billed a low hourly rate for every hour in the term regardless of usage.

Can I modify my Reserved Instance terms after purchasing?

No, once you have purchased your Reserved Instance, modifications of RI terms cannot be made in Amazon RDS for MariaDB. You are unable to change the DB instance class, DB engine, DB Edition, Region, Deployment Type, or term length after you purchase your RIs. For more details, visit the Reserved Instance page.
