Database instance size can be selected to meet your requirements. Instance size defines vCPU count and memory.
Available instance sizes are topology-specific and region-specific.
All database nodes within a service use the same instance size.
Enterprise Server Single Node
Enterprise Server With Replica(s)

Initial Instance Size
Initial instance size is defined at time of service launch.
With auto-scaling of nodes, Up/Down (vertical) scaling of instance size can be triggered automatically based on load.
Instance size can be manually changed after launch using Self-Service Operations.
