Are My RDS DB Instances Still Available During Storage Scale-up and Instance Class Change?
Currently, you can scale up storage space and change the vCPU 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.
- During the change of the vCPU or memory, the network is intermittently disconnected for one or two times in seconds. A failover may occur during this period and services may be briefly interrupted. Changing the vCPU or memory takes 5 to 15 minutes.
After you change the vCPU or memory, the DB instances will reboot and services will be interrupted. Therefore, you are advised to change instance classes during off-peak hours.
