Instance Family¶
Overview¶
An instance is a purchased BMS. Different instance types provide varied computing capabilities, storage space, and network performance. You can select a type that meets your service requirements.
BMS Types¶
The cloud platform provides a variety of BMS flavors that you can choose from.
Compute-optimized
This BMS type uses SDI iNICs and supports OLTP databases with higher performance, higher memory ratio, and transactional workloads cache.
