What is the basis for billing by peak traffic - ApsaraMQ for Kafka

Peak traffic defines the data processing capability of an ApsaraMQ for Kafka instance, not just its network bandwidth. When you select a peak traffic tier, you are provisioning the overall throughput capacity of the entire cluster.

How peak traffic determines data processing capability

The daily data processing capability of an instance is derived from its peak traffic:

Data processing capability = Peak traffic x Duration

Example: An instance with a peak traffic of 30 MB/s can process at least 2.47 TB of data per day:

30 MB/s x 60 s x 60 min x 24 h / 1024 / 1024 = 2.47 TB/day

Use this formula to calculate the minimum daily processing capability for any peak traffic value. The following table shows additional examples:

Peak traffic	Minimum daily processing capability
20 MB/s	~1.65 TB/day
30 MB/s	~2.47 TB/day
60 MB/s	~4.94 TB/day
120 MB/s	~9.89 TB/day

Note

These values are calculated from the formula above. Actual processing capability may be higher than the listed minimum.
