What it shows

  • Identical Blue and Green environments run side-by-side in production.
  • Ingress controller switches 100% of user traffic in milliseconds.
  • Instant rollback requires only flipping the ingress route back to Blue.

The takeaway

Blue-green decouples deployment from release, eliminating downtime and slashing rollback time to seconds.
