A blue-green deployment strategy involves running two identical production environments, "Blue" (the current version) and "Green" (the new version), in parallel. All incoming traffic is routed to the current (Blue) environment. The new version (Green) is deployed and thoroughly tested in its own separate environment. Once validated, traffic is instantly switched from Blue to Green.
