Understanding Kafka’s Engineering Costs

What this post added

This post analyzes the engineering costs of running Kafka, breaking them down into infrastructure, development, and operations. It quantifies these costs by estimating the number of engineers required for different scales of operation and their associated salaries and fully loaded employment costs. It also discusses capacity planning challenges, the need for platform development beyond core Kafka (e.g., connectors, security, monitoring), and the complexities of cluster scaling and ongoing maintenance. The post highlights the opportunity cost of dedicating engineering talent to infrastructure management versus strategic business initiatives and contrasts these self-managed costs with the benefits of managed services like Confluent Cloud.
