Cost comparisons among Kinesis, MSK and Confluent Cloud (on AWS)? I was trying to estimate the cost of building a stream pipeline using different options on the table.


On Confluent Cloud cost estimator page 
I assume I have a 2MB/s write to the stream pipeline and a 2MB/s read from the stream
 - ‘region’ — ‘US-East-1’
 - ‘cluster’ — ‘basic’ 
 - ‘availability’  — ‘multi-zone’
 - ‘storage’ — ‘100GB’
 - partitions — ‘3’

The cost is $1365

On the Kinesis cost estimator page:
 - I assume the above 2MB/s as 1024 msg/s * 2k / msg 
 - used the default (24hr) retentions 
 - number of consumer app — 1
 - number of enhanced fan out— 1

The Kinesis stream cost is $148

Why there is such a 10x cost difference? What Confluent cloud gives me extra by charging 10x more?
