In this episode, Martin Jensen, Head of Engineering, breaks down the true cost of scaling for peak demand. He explains the limits of autoscaling, when pre-scaling makes sense, and how tools like virtual waiting rooms are used to handle sudden spikes in traffic. Martin also discusses system bottlenecks, performance trade-offs, and practical strategies for staying in control during high-demand moments like ticket sales, product drops, and popular registrations.
