Accurate Azure Disk TX Cost

Due to the way we calculate IO cost by assuming the worst case, it can result in extremely inaccurate disk costs in Azure (25%). And since disk costs dominate Azure Kafka costs, it can directly result in a deployment cost that’s up to 25% inaccurate! (🚨🚨🚨)

Max Cluster Size

As mentioned in the docs, the maximum cluster size relates a lot to the disk space limitation

Account for Zookeeper / KRaft nodes

The calculator currently doesn’t account for KRaft/ZooKeeper nodes. This issue tracks adding support for it. - What instance should it be? - how many - etc

Cluster Utilization Buffer / Performance Buffer / Avg-Max Throughput / Latency Profile

As mentioned in the docs, the calculator could use one of the following: high-level: latency profiles: some sort of pre-made latency profiles which chooses "low latency < 100ms", med latency "< 250ms p99" and etc. Then, the calculator chooses the right disk and buffer based on that. avg-max throughput: allow users to define their avg throughput for cost calculating purposes (e.g network charges) but configure a max that the cluster must be able to support without trouble at all times low-level: an IOPS utilization buffer. e.g ensure we only use 50% of provisioned IOPS
