Are My RDS DB Instances Available When Scaling?

Currently, you can scale up storage space and change the CPU or memory of a DB instance.

When scaling storage space, RDS DB instances are available and services are not affected. However, you cannot delete or reboot DB instances that are being scaled.
When changing the CPU or memory of DB instances, the network is intermittently disconnected for one or two times within 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 interrupted for a short period of time.
