Summary
#362: Feature flags or canary deployments - do you need both? Viktor puts it to Alex Casalboni from Unleash, who says he argues about this with his colleagues roughly every day, and the answer lands clean. Switching a hostname, a database, an API vendor? That is infrastructure, nothing to do with who the user is, so keep your canaries and your blue-green. But a canary switches one thing at a time. Try running three A/B tests and ten behavioral changes through it and the whole approach buckles. Anything that needs to know who the user is belongs in a flag. Different layers of the stack, different tools, and most teams will end up with both whether they planned to or not. Back up, though, because there is a new word attached to all of this. FeatureOps. There is a manifesto and everything, sitting at [featureops.io](https://featureops.io/), reading a lot like someone nailed 95 theses about feature flags to a door. Real discipline, or marketing wrapper? Alex gets about ten seconds of pleasantries before he has to answer for the word. His defense is narrower than the name suggests, and better for it: every ops discipline we have gets you to the deployment and then waves goodbye. Something breaks, you go around the whole loop again - hotfix, pipeline, 20 or 30 or 60 minutes, fingers crossed. FeatureOps is the claim that the same principles apply after the code is already running. Runtime control. Alex says enterprise customers routinely have a 12 to 24-hour round trip between finding a problem and getting the fix live. Even for a hotfix. Viktor is not letting the seconds claim through unchallenged. If it takes you a day to notice and two seconds to flip, that is a day and two seconds - so stop measuring from the convenient starting line. Alex concedes the framing and then go…
