A deployment strategy that maintains two identical production environments, routing traffic to the new version only after it's verified healthy.
Blue-green deployment keeps the current version (blue) running while the new version (green) is deployed and tested in parallel. Once verified, traffic switches from blue to green. If issues arise, instant rollback is possible by switching traffic back to blue.
Deploying a new version of the Django backend to a green environment, running smoke tests, then updating Nginx to route traffic to the new version.
Blue-green deployments eliminate downtime and provide instant rollback — critical for production systems where availability matters.
