ApsaraDB RDS provides high-performance database instances. These database instances support features such as parameter optimization and SQL optimization.
Parameter optimization
All parameters that are used in ApsaraDB RDS have been tested and optimized over years of production practices that are conducted by a team of experienced database administrators (DBAs) from Alibaba Cloud. These DBAs have continued to optimize each ApsaraDB RDS instance throughout the lifecycle of the instance to ensure that the instance runs at its optimal configuration.
SQL optimization
ApsaraDB RDS identifies SQL statements that are run at low speeds and provides recommendations that help you optimize your business code.
High-end hardware
All server hardware that is used by ApsaraDB RDS has passed the tests of multiple concerned parties. This ensures that ApsaraDB RDS can deliver optimal performance and high stability.
High-speed access
If an ApsaraDB RDS instance is used with an Elastic Compute Service (ECS) instance that resides in the same region as the RDS instance, these instances can communicate over an internal network to shorten response time and reduce Internet traffic consumption.
