Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
  • Minimum commitment recommended for cost optimization

Kubernetes

  • Complex initial setup and configuration with multiple interdependent components
  • Significant resource requirements for both hardware infrastructure and specialized human expertise
  • Expensive specialized talent in Kubernetes domain; hiring costs prohibitive for many organizations
  • New security challenges around container isolation and network security requiring robust measures
  • Requires continuous maintenance and updates to stay current with releases and security patches
