Compute nodes of ApsaraDB PolarDB MySQL-compatible edition Cluster Edition are classified into two types: General-purpose and Dedicated. This topic describes the differences between the two types of compute nodes.

Compute node types

Type Feature Scenario
ApsaraDB PolarDB MySQL-compatible edition Cluster Edition Dedicated
  • A cluster of Dedicated occupies all of the allocated compute resources, such as vCPUs.
  • Compute resources are not shared with other clusters that run on the same server. This improves the reliability and stability of the cluster that occupies these resources.
Scenarios where databases are the key component of business systems that require high stability, such as finance, e-commerce, public service sectors, and large or medium-scale Internet services.
ApsaraDB PolarDB MySQL-compatible edition Cluster Edition General-purpose
  • Idle compute resources, such as idle vCPUs, are shared among clusters that run on the same server.
  • Resource sharing allows you to deploy a large number of clusters at low costs.
Scenarios where cost-effectiveness is required.
