What are rollback strategies in continuous delivery?
Rollback strategies are methods used to revert to a previous stable version of software after a failed deployment.
Can you explain some common rollback strategies?
Sure! Common strategies include blue-green deployments, canary releases, and feature toggles.
How do blue-green deployments work?
In blue-green deployments, two identical environments are maintained. One is live (blue) while the other (green) is idle. After deployment, traffic is switched to the green environment if everything works well.
What are the risks of not having a rollback strategy?
Without a rollback strategy, you risk prolonged downtime, user dissatisfaction, and potential data loss.
