A serverless cold start is the delay that occurs when the cloud platform has to wake up a function that's been idle. The platform needs to load your code, pull in dependencies, and spin up a new runtime environment from scratch, which can take hundreds of milliseconds to seconds. This delay directly impacts the user who initiated the request, creating a poor first impression even if subsequent requests are instant.
