Question

Quizplus · Accepted Answer

Miriam has chosen a blue-green deployment strategy, where she maintains two identical environments: one active (green) and one idle (blue). After testing the update in the idle environment, she switches traffic to it, effectively making it the new active environment. This approach minimizes downtime and allows for quick rollback if needed.
