# Amazon AuroraDB instance classes
The DB instance class determines the computation and memory capacity of an Amazon Aurora DB instance. The DB instance class that you need depends on your processing power and memory requirements.
A DB instance class consists of both the DB instance class type and the size. For example, db.r6g is a memory-optimized DB instance class type powered by AWS Graviton2 processors. Within the db.r6g instance class type, db.r6g.2xlarge is a DB instance class. The size of this class is 2xlarge.
For more information about instance class pricing, see [Amazon RDS pricing](https://aws.amazon.com/rds/pricing/).

# Hardware specifications for DB instance classesfor Aurora
In the table in this section, you can find hardware details about the Amazon RDS DB instance classes for Aurora.
For information about Aurora DB engine support for each DB instance class, see [Supported DB engines for DB instance classes](Concepts.DBInstanceClass.SupportAurora.md).
**Topics**
+ [Hardware terminology for DB instance classesfor Aurora](#Concepts.DBInstanceClass.hardware-terminology)
+ [Hardware specifications for the memory-optimized instance classes](#hw-specs-aur.mem-opt)
+ [Hardware specifications for the burstable-performance instance classes](#hardware-specifications.burstable-inst-classes)
## Hardware terminology for DB instance classesfor Aurora
The following terminology is used to describe hardware specifications for DB instance classes:
**vCPU**
The number of virtual central processing units (CPUs). A *virtual CPU *is a unit of capacity that you can use to compare DB instance classes. Instead of purchasing or leasing a particular processor to use for several months or years, you are renting capacity by the hour. Our goal is to make a consistent and specific amount of CPU capacity available, within the limits of the actual underlying hardware.
**ECU**
The relative measure of the integer processing power of an Amazon EC2 instance. To make it easy for developers to compare CPU capacity between different instance classes, we have defined an Amazon EC2 Compute Unit. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. One ECU currently provides CPU capacity equivalent to a 1.0–1.2 GHz 2007 Opteron or 2007 Xeon processor.
**Memory (GiB)**
The RAM, in gibibytes, allocated to the DB instance. There is often a consistent ratio between memory and vCPU. As an example, take the db.r4 instance class, which has a memory to vCPU ratio similar to the db.r5 instance class. However, for most use cases the db.r5 instance class provides better, more consistent performance than the db.r4 instance class.
**Max. EBS bandwidth (Mbps)**
The maximum EBS bandwidth in megabits per second. Divide by 8 to get the expected throughput in megabytes per second.
This figure refers to I/O bandwidth for local storage within the DB instance. It doesn't apply to communication with the Aurora cluster volume.
**Network bandwidth**
The network speed relative to other DB instance classes.
For information on using Amazon CloudWatch metrics to monitor your Aurora DB instance throughput, see [Evaluating DB instance usage for Aurora MySQL with Amazon CloudWatch metrics](AuroraMySQL.BestPractices.CW.md) and [Evaluating DB instance usage for Aurora PostgreSQL with CloudWatch metrics](AuroraPostgreSQL_AnayzeResourceUsage.md#AuroraPostgreSQL_AnayzeResourceUsage.EvaluateInstanceUsage).
