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. You can choose BMS flavors that best suit your needs.

• General-purpose

  This BMS type uses Intel Xeon Skylake CPU and meets the requirements for dedicated resources, isolated networks, and basic performance in scenarios such as databases, core ERP systems, and financial systems.

  Table 1 General-purpose BMS specifications

  Flavor Name/ID	CPU	Memory	Local Disk	Extended Configuration
  physical.s4.3xlarge	2 x 22 Core Intel Xeon Skylake Gold 6161 (2.20 GHz/2.70 GHz)	DDR4 RAM (384 GB)	None	2 x 2-port 10GE

• Compute-optimized

  This BMS type uses SDI iNICs and supports OLTP databases with higher performance, higher memory ratio, and transactional workloads cache.
