Why the totals differ

Google Cloud is significantly cheaper for this Extra Small Kafka deployment, costing less than $1 monthly compared to over $2800 on AWS and $3100 on Azure. This dramatic difference is due to Google Cloud's sustained use discounts, which are not explicitly modeled in the AWS and Azure on-demand pricing for this service. While on-demand pricing is used across the board, the underlying pricing models for Kafka services vary greatly between providers. A commitment term or reservation on AWS or Azure would likely reduce their costs, but Google Cloud's sustained use is the primary cost driver here.
