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.
High-performance computing
This BMS type provides a large number of CPU cores, large memory size, and high throughput. These BMSs use Intel Skylake V5 CPUs and InfiniBand NICs and can be quickly provisioned.

2 x 18 Core Intel Skylake 6151 V5 (3.0 GHz)
DDR4 RAM (192 GB)
1 x 1.6TB NVMe SSD
1 x 100G IB + 2-port 10GE
I/O-optimized
This BMS type uses SSD disks as both the system and data disks and does not support cloud storage. It is ideal for services that require local high I/O storage or Intel SGX-based trusted execution environments (TEE).
