Why compare a canary against a baseline running the old version at the same time?
- ✓Correct answer: Both get the same traffic, so differences come from the code
- 2The old version must keep running for licensing reasons
- 3Comparing against history is impossible in Kubernetes
Explanation
Comparing with last week's numbers mixes in traffic patterns and incidents. A same-size baseline deployed alongside isolates the effect of the change.
