RDS for MariaDB Instance Classes

To learn about the DB engine versions supported by RDS for MariaDB, see DB Engines and Versions.

Table 1 lists the instance classes based on the x86 CPU architecture available to RDS for MariaDB instances using cloud SSDs.

Table 1 Instance classes

Instance Class

Description

Scenario

Constraints

General-purpose (recommended)

CPU resources are shared with other general-purpose DB instances on the same physical machine. CPU usage is maximized through resource overcommitment. This instance class is a cost-effective option and suitable for scenarios where performance stability is not critical.

Suitable for scenarios that have high requirements on cost-effectiveness.

Table 2 lists the regions where this instance class is available.

Dedicated (recommended)

The instance has dedicated CPU and memory resources to ensure stable performance. The performance of a dedicated instance is never affected by other instances on the same physical machine. This instance class is good when performance stability is important.

Suitable for core database scenarios such as e-commerce, gaming, finance, government, and enterprise applications.

Table 2 lists the regions where this instance class is available.
