What Are the Differences Between the General-Purpose, Dedicated, and Kunpeng Dedicated Specification Types Provided GaussDB?

GaussDB instances support the x86 or Arm architecture, and the specification types supported by different architectures are as follows. For details about the differences between them, see Table 1.

  • x86: Dedicated (1:4), Dedicated (1:8), and General-purpose (1:4). 1:4 and 1:8 refer to the vCPU-to-memory ratio.
  • Arm: Kunpeng dedicated (1:4) and Kunpeng dedicated (1:8)

Instance Specifications

Supported Instance Type

Description

General-purpose

Basic edition

This type of specifications uses general-computing ECSs, which prioritize resource performance sharing and offer better cost-effectiveness. However, if the database is heavily loaded, it can lead to performance contention and fluctuations in computing performance. Consequently, this specification type is not suitable for large applications, and it is not offered in the enterprise edition.

Dedicated
  • Basic edition
  • Enterprise edition

This type of specifications uses general computing-plus x86 ECSs. Such ECSs ensure that there is no resource contention between instances and provide stable performance.

Kunpeng dedicated
  • Basic edition
  • Enterprise edition

This type of specifications uses general computing-plus Kunpeng ECSs. Such ECSs ensure that there is no resource contention between instances and provide stable performance. This specification type is mainly used in IT application innovation scenarios.
