FAQ
When does Lambda win vs EC2? +
Below ~30% utilization Lambda is cheaper. Above 50%, VMs win. Use both — Lambda for spiky APIs, VMs for steady workloads.
Lambda cold starts? +
Cold starts add 100-500ms. Provisioned concurrency eliminates them but charges 24/7 like a VM. Defeats the point for low-traffic functions.
