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.
