ApsaraDB for MongoDB provides general and dedicated instance type families.
Instances that have exclusive use of CPU, memory, storage, and I/O resources. Instances of this type family feature high performance and stability and are independent of other instances running on the same physical server.
The top configuration of this type family is the Exclusive physical machine (also called the DDH), which exclusively occupies all resources owned by a physical server.
|A database is a core component of certain businesses, such as finance, e-commerce, government, and large and medium-sized online businesses.|
For more information about instance types and specifications such as the number of CPU cores, memory, storage space, maximum number of allowed connections, and IOPS, see Instance types.
For the price of each instance type, see Billing items and pricing.
