Blue/Green Deployments with Coordinated DB Migrations
A deployment strategy that runs a new app version beside the old and switches traffic when safe, while coordinating database schema changes to avoid downtime or data loss.
"I want to flip to a new release without locking the database or breaking in-flight requests."
Blue/green deployment separates traffic between two environments (blue and green) and switches users to the new one once validated; coordinated DB migrations stage backwards-compatible schema changes, migrate data while both app versions run, then finalize breaking changes after cutover.
