Serverless vs Premium/Dedicated Functions — The Cost Crossover
Understand cold start tradeoffs, when serverless breaks down at scale, and how to find the cost crossover point for your workload.
Serverless is one of those technologies that seems like a silver bullet until you hit the edge cases. At low scale, it is practically free. At medium scale, it is cost-effective and operationally simple. At high scale, the economics flip — and suddenly, a dedicated server running 24/7 is cheaper than paying per millisecond.
Understanding where that crossover point lives for your specific workload is one of the most important infrastructure decisions you will make. Get it right and you save money while maintaining simplicity. Get it wrong and you either overpay for serverless at scale or over-engineer with dedicated infrastructure when serverless would have been fine.
