The compute nodes for PolarDB for MySQL Cluster Edition and Multi-master Cluster (Limitless) Edition are available in two specification types: General-purpose and Dedicated. This topic describes the differences between these two specification types to help you choose the right one.
Comparison between General-purpose and Dedicated specifications
Specification type | Features | Scenarios |
Dedicated |
| Scenarios that require high performance and stability, where the database is a core part of the system. This includes finance, e-commerce, government services, and large or medium-sized internet businesses. |
General-purpose |
| Cost-sensitive scenarios that require high cost-effectiveness. |
Node specifications and prices
Cluster Edition
The following table compares the details and prices of General-purpose and Dedicated node specifications for PolarDB for MySQL Cluster Edition.
The prices in the table are for a single compute node of a PolarDB for MySQL Cluster Edition cluster in the Chinese mainland. For the prices of compute nodes in other regions, see Compute nodes.
Maximum IOPS values are theoretical values. It is not guaranteed that these nominal values can be accomplished under any conditions.
Clusters in a Global Database Network (GDN) do not support 2-core 4 GB and 2-core 8 GB node specifications.
