Instance
- An instance is a basic management unit of DDS. One or more databases can be created in a single DDS instance, and one or more collections can be created in each database.
- You can create and manage DB instances of various types and versions on the management console. For details about DB instance types, versions, and specifications, see Instances.
- Resources, such as the CPU, memory, and I/O, of each DDS DB instance are isolated from each other.
