Edition Types of DB Instances

GaussDB offers two editions: basic edition and enterprise edition. The enterprise edition stands out for its exclusive advanced features, including advanced compression, anti-tampering, dynamic data masking, multitenancy, and transparent data encryption. Additionally, the enterprise edition will continuously introduce new advanced features that are not available in the basic edition. The basic edition of GaussDB is positioned as a cost-effective option but does not include any advanced features. The basic edition delivers the same level of performance as the enterprise edition at a more affordable price. This edition is ideal for users who prioritize cost and do not need advanced features.

For more details about the differences between the two editions, see Table 1.

Supported Deployment Model	Centralized 1 primary + 2 standby 1 primary + 1 standby + 1 log Single Distributed Combined	Centralized 1 primary + 2 standby 1 primary + 1 standby + 1 log Single Distributed Independent
Available Instance Specifications	Supported specification types: General-purpose Dedicated Kunpeng dedicated	Supported specification types: Dedicated Kunpeng dedicated
	Minimum specifications: Centralized 4 vCPUs \| 16 GB (General-purpose, Dedicated, and Kunpeng dedicated) Distributed Combined deployment: 16 vCPUs \| 64 GB (Dedicated and Kunpeng dedicated) NOTE: For a combined deployment, all components must be deployed on a single ECS, which demands higher CPU resources to maintain optimal performance. As a result, a minimum of 16 vCPUs is necessary for a combined deployment.	Minimum specifications: Centralized 4 vCPUs \| 16 GB (Dedicated and Kunpeng dedicated) Distributed Independent deployment: 8 vCPUs \| 64 GB (Dedicated and Kunpeng dedicated)
	Maximum specifications: x86: 64 vCPUs \| 512 GB Arm: 60 vCPUs \| 480 GB	Maximum specifications: x86: 64 vCPUs \| 512 GB Arm: 60 vCPUs \| 480 GB
Advanced Feature	Advanced compression, anti-tampering, dynamic data masking, multitenancy, and transparent data encryption are not available.	All advanced features are supported.
Performance (Benchmark: Enterprise Edition)	Centralized instance: same as the enterprise edition Distributed instance in a combined deployment: 50% of the performance of the enterprise edition, when the same specifications are configured	-
Price (Benchmark: Enterprise Edition)	When the specifications are the same, the cost of a centralized instance in the basic edition is about 30% of the cost of the enterprise edition. When the specifications are the same, the cost of a distributed instance in a combined deployment of the basic edition is about 7.5% of the cost of the enterprise edition.	-
