Single Node

Huawei Cloud has discontinued the sale of DDS single node instances since July 15, 2023.

A single node instance, as its name suggests, contains only one node and that node can be accessed directly.

As a supplement to the cluster and replica set architectures, the single-node architecture is useful for R&D, SQL commissioning, and lab project testing. While not as robust as replica sets, single node architecture can be a less expensive way to visualize O&M and provide elastic scaling.
