Hidden Costs Breakdown

1

Cloud Provider Markup

critical implementation

Running ClickHouse on AWS or other major cloud providers incurs significant markup compared to self-hosting on dedicated servers. The same workload that costs under $100/month on a VPS can cost $4,000/month on AWS.

our ClickHouse server on AWS cost around $4,000 per month, whereas our own VPS setup costs less than $100 per month and offers at least ten times the capacity.

SQL Compatibility Gaps Requiring Workarounds

medium implementation

ClickHouse doesn't support many standard SQL constructs that users rely on, requiring code rewrites, denormalization, or workarounds. This adds engineering time and complexity to migration and ongoing development.

Operational Complexity for Self-Hosted Deployments

Self-hosting ClickHouse requires managing OS updates, automated backups, monitoring, and ongoing maintenance. While cost-effective on infrastructure, it's an expensive use of engineering time.

Having to stay on top of OS updates, automated backup, monitoring, ... is an expensive use of my time when I could be using it to work on my actual project.

Join Performance Requiring Denormalization
