Concepts of Dark launches are useful when you want to launch a new version of an existing service

I have a pleasure to recall that, Adrian Hilton, Customer Reliability Engineer in its first part of this series introduced us to the concept of dark launches.

In fact, in a dark launch, you take a copy of your incoming traffic and send it to the new service, then throw away the result.

Dark launches are useful when you want to launch a new version of an existing service, but don’t want wrong surprises when you turn it on.
