AWS offers Previous Generation DB Instances for users who have optimized their applications around these instances and have yet to upgrade. Previous Generation DB Instances are still fully supported and retain the same features and functionality. Previous Generation DB Instances are available through the AWS management console, CLI and API tools.

We encourage you to use the latest generation of instances to get the best performance, but we will continue to support Previous Generation DB Instances after new instances launch. If you are currently using a Previous Generation DB Instance and would like to see which one would be a suitable upgrade, see the table below and learn how the latest generation of DB Instances could benefit you. 

M4 instances provide better, more consistent performance than M1 instances under most circumstances. M4 instances are also less expensive than M1 instances.

M1   M4
No Latest Intel Xeon Processor Yes
No
Enhanced Networking Yes
Good I/O Performance Better
Good Price per Performance
Better

R3 instances provide the latest Intel Xeon Processors, higher memory bandwidth, and superior I/O and network performance. Certain R3 instance types also offer support for EBS optimization. R3 instances offer a very cost-effective price per GiB of RAM.

 

 

 

 

M2   R3  
No Latest Intel Xeon Processors Yes  
No Enhanced Networking Yes  
Good Sustained memory bandwidth Better  
Good I/O performance Better  
Good Memory per instance Better  
Good Price point per GiB of RAM Best  

R3 instances are recommended for high-performance database instances, particularly for workloads in which operations can be completed out of the database engine's memory cache. Choose M3 instances for database instances that face heavy write traffic, or for which a somewhat lower price point is sought.

 

T2 instances are Burstable Performance Instances that provide a baseline level of CPU performance with the ability to burst above the baseline. They are recommended for workloads that don't use the full CPU often or consistently, but occasionally need to burst to higher CPU performance, such as small database workloads in test and developer environments. T2 DB Instances are less expensive than m1.small, m1.medium, and t1.micro instances in most regions.

T1/M1.small   T2
No Latest Intel Xeon Processors
Yes
No Turbo up to 3.3GHz
Yes

You can change your DB Instance type right from the AWS Management Console. Select the desired instance, click the "Modify" button, and choose a different instance class. You can also use the ModifyDBInstance API. More information about scaling is available in the RDS FAQ document's Hardware and Scaling section.

 


Just like our current Instances, Previous Generation DB Instances give you access to the capabilities of a familiar MySQL, Oracle, Microsoft SQL Server, or PostgreSQL database engine, 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. It also frees you up from the undifferentiated labor of managing relational databases, letting you focus on your applications and your customers.

Instance Type vCPU Memory (GiB) PIOPS-Optimized Network Performance
Standard - previous generation
db.m1.small 1 1.7 - Low
db.m1.medium 1 3.75 - Moderate
db.m1.large 2 7.5 Yes Moderate
db.m1.xlarge 4 15 Yes High
Memory optimized - previous generation
 
db.m2.xlarge 2 17.1 - Moderate
db.m2.2xlarge 4 34.2 Yes Moderate
db.m2.4xlarge 8 68.4 Yes High
Micro instances
db.t1.micro 1 0.613 - Very Low

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.

The pricing below applies to a DB Instance deployed in a Single Availability Zone.

Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of AWS is subject to Japanese Consumption Tax. Learn more.

When you run your DB Instance as a Multi-AZ deployment for enhanced data durability and availability, Amazon RDS provisions and maintains a standby in a different Availability Zone for automatic failover in the event of a scheduled or unplanned outage. Learn more about Multi-AZ deployments.

Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of AWS is subject to Japanese Consumption Tax. Learn more.

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 terminated. Each partial DB Instance-hour consumed will be billed as a full hour.

Amazon RDS Reserved Instances give you the option to reserve capacity within a datacenter and in turn receive a significant discount on the hourly charge for instances that are covered by the reservation. 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 and receive a significant discount over On-Demand prices. To learn more about Reserved DB Instances, please visit our Reserved Instances page.

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

Please note the one-time fee per DB Instance is non-refundable.

Under the "License Included" service model, you do not need separately purchased Oracle licenses; the Oracle Database software has been licensed by AWS. "License Included" pricing is inclusive of software, underlying hardware resources, and Amazon RDS management capabilities.

On-Demand DB Instances for the License Included model 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.

Under the Bring Your Own License (“BYOL”) model, you can run Amazon RDS using your existing Oracle Database software licenses. You can also purchase Oracle Database 11g licenses directly from Oracle and run them on Amazon RDS.

To run a DB Instance under the BYOL model, you must have the appropriate Oracle Database license (with Software Update License & Support) for the DB Instance class and Oracle Database edition you wish to run. You must also follow Oracle's policies for licensing Oracle Database software in the cloud computing environment. DB Instances reside in the Amazon EC2 environment, and Oracle's licensing policy for Amazon EC2 is located here.

On-Demand DB Instances for the BYOL model also let you pay for compute capacity by the hour your DB Instance runs with no long-term commitments.

Supported under this model: Enterprise Edition, Standard Edition, Standard Edition One and Standard Edition Two. Charges do not vary by edition for BYOL Amazon RDS pricing.

Microsoft’s License Mobility program (referred to henceforth as Bring Your Own License or "BYOL") allows customers who already own SQL Server licenses to run SQL Server deployments on Amazon RDS. This benefit is available to Microsoft Volume Licensing (VL) customers with SQL Server licenses (currently including Standard and Enterprise Editions) covered by active Microsoft Software Assurance (SA) contracts. The Microsoft License Mobility program is suited for customers who prefer to use existing SQL Server licenses or purchase new licenses directly from Microsoft or any other reseller. To run a DB Instance under the BYOL model, you must meet the eligibility requirements and follow the Sign Up process laid out here. You must also have the appropriate SQL Server licenses with Software Assurance for the DB Instance class and SQL Server edition you wish to run, and must adhere to Microsoft’s licensing policies.

Supported under this model: Standard Edition and Enterprise Edition. AWS charges are the same for each edition supported under this model. The pricing below applies to a DB Instance deployed in a single Availability Zone.
