ApsaraDB for Redis supports Pay-As-You-Go instances, and the instance configuration can be changed in real time.
Changing instance configuration will incur a change in charges. For more information about the billing standard, see ApsaraDB for Redis pricing details.
Pay-As-You-Go instances support real-time configuration upgrade/downgrade.
Cluster instances and master-slave instances support mutual configuration upgrade/downgrade.
The instance will experience intermittent interruption for several seconds during configuration change, so perform upgrade during off-peak hours if possible.
Log on to the Redis console.
Find the target instance and click Change Configuration.
On the Change Configuration page, select the expected configuration and click Confirm to Change.
You will be prompted after the configuration is successfully changed. If the instance is Pay-As-You-Go, it will be billed for the new configuration starting from the billing cycle when the change occurred.
