Amazon RDS instance types
Why Amazon RDS instances?
Amazon RDS provides a selection of instance types optimized to fit different relational database use cases. Instance types comprise varying combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your database. Each instance type includes serveral instance sizes, allowing you to scale your database to the requirements of your target workload.
Not every instance type is supported for every database engine, version, edition or region. Please see the database engine-specific pricing pages for details. Looking for M1, M2, M3 or R3 instances? See the Previous Generation Instances page.
General Purpose
T4g
T4g instances are the next generation burstable general purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. T4g instances offer a balance of compute, memory, and network resources and are ideal for database workloads with moderate CPU usage that experience temporary spikes in use.
T4g instances accumulate CPU credits when a workload is operating below baseline threshold. Each earned CPU credit provides the T4g instance the opportunity to burst with the performance of a full CPU core for one minute when needed. Amazon RDS T4g instances are configured for Unlimited mode, which means they can burst beyond the baseline over a 24-hour window for an additional charge.
Features:
Custom built AWS Graviton2 Processor with 64-bit Arm Neoverse cores
Burstable CPU, governed by CPU Credits, and consistent baseline performance
Unlimited mode to ensure performance during peak periods
Powered by the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor

Instance Features
Amazon RDS database instances provide a number of additional features to help you deploy, manage, and scale your database workloads.
Burstable Performance Instances
Amazon RDS allows you to choose between Fixed Performance Instances (e.g. M5 and R5) and Burstable Performance Instances (e.g. T3). Burstable Performance Instances provide a baseline level of CPU performance with the ability to burst above the baseline.
Amazon RDS T3 instances can sustain high CPU performance for as long as a workload needs it. For most general-purpose workloads, T3 instances will provide ample performance without any additional charges. The hourly T3 instance price automatically covers all interim spikes in usage when the average CPU utilization of a T3 instance is at or less than the baseline over a 24-hour window.
T3 instances’ baseline performance and ability to burst are governed by CPU Credits. Each T3 instance receives CPU Credits continuously, the rate of which depends on the instance size. T3 instances accrue CPU Credits when they are idle, and use CPU credits when they are active. A CPU Credit provides the performance of a full CPU core for one minute.
For example, a db.t3.small instance receives credits continuously at a rate of 12 CPU Credits per hour. This capability provides baseline performance equivalent to 20% of a CPU core (20% x 60 mins = 12 mins). If the instance does not use the credits it receives, they are stored in its CPU Credit balance up to a maximum of 288 CPU Credits. When the t3.small instance needs to burst to more than 20% of a core, it draws from its CPU Credit balance to handle this surge automatically.
Amazon RDS T3 instances can burst above the baseline even when its CPU Credit balance is zero. For a vast majority of database workloads where the average CPU utilization is at or below the baseline performance, the basic hourly price for t3.small covers all CPU bursts. If the instance happens to run at an average 25% CPU utilization (5% above baseline) over a period of 24 hours after its CPU Credit balance is drawn to zero, it will be charged an additional 9 cents (7.5 cents/vCPU-hour x 1 vCPU x 5% x 24 hours). See Amazon RDS Pricing for pricing details.
Many database workloads don’t need consistently high levels of CPU, but benefit significantly from having full access to very fast CPUs when they need them. Burstable Performance instances are engineered specifically for these use cases. If you need consistently high CPU performance for your database, we recommend you use Fixed Performance Instances.
Database Storage Options
Storage for Amazon RDS for MySQL, MariaDB, PostgreSQL, Oracle, and SQL Server is built on Amazon EBS, a durable, block-level storage service. Amazon RDS provides three volume types to best meet the needs of your database workloads: General Purpose (SSD), Provisioned IOPS (SSD), and Magnetic. General Purpose (SSD) is an SSD-backed, general purpose volume type that we recommend as the default choice for a broad range of database workloads. Provisioned IOPS (SSD) volumes offer storage with consistent and low-latency performance, and are designed for I/O intensive database workloads. Magnetic volumes provide a low cost per gigabyte and are provided for backwards compatibility.
Amazon Aurora features a distributed, fault-tolerant, self-healing storage system that auto-scales up to 128 TiB per database cluster. It delivers high performance and availability to power up to 15 low-latency read replicas and provides point-in-time recovery, continuous backup to Amazon S3, and replication across three Availability Zones (AZs).
EBS-optimized Instances
EBS-optimized instances enable Amazon RDS to fully use the IOPS provisioned on an EBS volume. EBS-optimized instances deliver dedicated throughput between Amazon RDS and Amazon EBS, with options between 500 and 4,000 Megabits per second (Mbps) depending on the instance type used. The dedicated throughput minimizes contention between Amazon EBS I/O and other traffic from your RDS instance, providing the best performance for your EBS volumes. EBS-optimized instances are designed for use with both Standard and Provisioned IOPS Amazon EBS volumes. When attached to EBS-optimized instances, Provisioned IOPS volumes can achieve single digit millisecond latencies and are designed to deliver at least 90% of the provisioned IOPS performance 99.9% of the time in a given year. We recommend using Provisioned IOPS volumes with EBS-optimized instances or instances that support cluster networking for applications with high storage I/O requirements.
Enhanced Networking
Enhanced Networking enables you to get significantly higher packet per second (PPS) performance, lower network jitter and lower latencies. This feature uses a new network virtualization stack that provides higher I/O performance and lower CPU utilization compared to traditional implementations. Amazon RDS automatically enables Enhanced Networking for supported database instance types.
