3.1 About DB Systems

A DB System is a logical container for the MySQL instance. It provides an interface enabling management of tasks such as provisioning, backup, monitoring, and so on. It also provides a read/write endpoint enabling you to connect to the MySQL instance using the standard MySQL protocols.

DB System Components

A DB System consists of the following components:

  • An Amazon EC2 instance type (with resources defined by the associated shape; see Supported Shapes for more information).

  • Oracle Linux Operating System


    It is not possible to access the operating system. Only the MySQL instance is exposed through the DB System endpoint.

  • MySQL Server Enterprise Edition. For more information, see MySQL Server.

  • Virtual Network Interface Card (VNIC) which attaches the DB System to a subnet of the Virtual Private Cloud (VPC). For connections to the DB System, a public endpoint is exposed as a fully-qualified domain name (FQDN). Specific IP addresses in CIDR format can be specified to limit access to the public endpoint.

  • Network-attached block storage. HeatWave on AWS uses Amazon EBS block storage. For more information, see Amazon Elastic Block Store (Amazon EBS) in the Amazon EC2 User Guide for Linux Instances.

DB System Storage

Storage size should be determined based on your data size and performance requirements.

For information about increasing the storage available to the DB System, see Increasing DB System Storage.
