GCF on GCP auto-scales (as does GAE & GCR). Each instance only supports one request at a time. Additional instances will be spun up to support other concurrent requests. If your function (or app or container) "goes viral," GCP automatically handles the traffic for you. However, not everyone has unlimited budget, so there's a way you can control the max # of instances spun-up. To learn more about concurrent requests, check out this page in our documentation: https://cloud.google.com/functions/docs/concepts/exec
