Are My RDS DB Instances Available When Scaling?
Updated at: Jun 09, 2021 GMT+08:00
Currently, you can scale up storage space and change the CPU or memory of a DB instance.
- When storage space is being scaled up, RDS DB instances are still available and services are not affected. However, you cannot delete or reboot DB instances that are being scaled.
- When the CPU or memory of DB instances is being changed, the network is intermittently disconnected once or twice within a few seconds. (For Microsoft SQL Server 2017 Enterprise Edition, you need to stop services first and then change the CPU or memory of DB instances.) For primary/standby DB instances, a failover may occur and services may be briefly interrupted.
