<p>This article describes how to create a DDS general instance quickly.</p> <p><strong><span style="font-size:18px">Usage Guidelines</span></strong></p> <p>1. When there is only one availability zone in the region where a general instance is created, the system will create a three-node replica set with one primary node and two secondary nodes in the same availability zone by default. For more information, see <a href="http://pinganyun.com/ssr/help/database/mongodb/index.Architecture" target="_blank">Basic Architecture</a> of 3+0+1.1 architecture.</p> <p>2. When there are two or more availability zones in the region where the general instance is created, the system will create three-node replica sets in the same region in different availability zones: one primary node and one secondary node in the primary availability zone; one citywide disaster recovery instance in another availability zone; For more information, see <a href="http://pinganyun.com/ssr/help/database/mongodb/index.Architecture" target="_blank">Basic Architecture</a> of 2+1+1.1 architecture.</p> <p>3. When a DDS general instance is created successfully, region and availability zone cannot be modified. The instance name is automatically generated by the system and cannot be modified, but you can manage it through customizing the instance tag.
