What's the difference between a Blue/Green Deployment and a Rolling Deployment?

The main differences between Blue/Green Deployment and Rolling Deployment are:

Blue/Green Deployment

• Requires two identical production environments, one active (Blue) and one idle (Green)[1][3][5]
• New version is deployed to the idle Green environment and tested[1][3]
• Traffic is then switched from Blue to Green to release the new version[1][3][5]
• Allows easy rollback by switching traffic back to the Blue environment if issues occur[1][3]
• Provides no downtime during deployment[1][3]

Rolling Deployment

• Deploys the new version gradually to different parts of the infrastructure[4]
• Allows the new version to be deployed to a subset of servers or containers at a time[4]
• Provides a way to test the new version with a small portion of traffic before full rollout[4]
• Allows the old and new versions to run concurrently during the rollout...
