Why do we call it that now, instead of A/B deployment like we used to?
- _asummers 9y agoTo me, blue/green is for infrastructure, and A/B is for the user side of it. That is, you should be able to do blue/green with the content not changing, but when you're A/B testing, you're collecting metrics and other usage data about the users to make future product decisions. You can also do A/B testing without having a B/G setup, using things like user gates. This distinction may be incorrect, but that's how I've used them.
- nine_k 9y agoA/B implies certain symmetry, while B/G is highly asymmetrical: G is known good, battle-tested, and B is new and suspicious.
