ApsaraDB for Redis supports the subscription and pay-as-you-go billing methods.
- An ApsaraDB for Redis instance is billed based on the specifications of the instance,
instead of the consumed cache space.
For example, if you purchase an ApsaraDB for Redis instance of 2 GB memory and store 256 MB of data on this instance, the instance is billed for the 2 GB memory capacity.
- The internal network traffic that is consumed by an ApsaraDB for Redis instance is free of charge. No fees are charged for data transmission between an Elastic Compute Service (ECS) instance and an ApsaraDB for Redis instance.
