x86-based Instance Specifications

TaurusDB for PostgreSQL supports the following x86-based instance specifications for the cloud SSD storage type: general-purpose (recommended) and dedicated (recommended). For details, see Table 1 and Table 2.

**Table 1** x86-based instance specifications
Instance Specifications	Description	Scenario	Constraints
General-purpose (recommended)	CPU resources are shared with other general-purpose DB instances on the same physical machine. CPU usage is maximized through resource overcommitment. It is a cost-effective option and suitable for scenarios where stable performance is not critical.	Suitable for scenarios that have high requirements on cost-effectiveness.	These instance specifications are available in the following regions: AP-Singapore AP-Bangkok TR-Istanbul LA-Sao Paulo1 ME-Riyadh
Dedicated (recommended)	Your instance gets dedicated vCPUs and memory, so the performance is stable. It is not affected by other instances on the same physical machine. Dedicated instances are good for scenarios that require stable performance.	Suitable for core database scenarios such as e-commerce, gaming, finance, government, and enterprise applications.
