Overview
A release pattern that switches traffic from one environment to another.
Definition
A release pattern that switches traffic from one environment to another.
Real-world example
Blue runs v1.2 in production; green builds v1.3 on the same server. Traffic flips to green only after smoke tests succeed.
Common mistake
Sharing one database schema between blue and green without backward-compatible migrations.
Better-PaaS in practice
Better-PaaS uses a simpler model: new container + health gate + traffic switch. For true dual environments, run separate apps or servers.
FAQ
Is blue-green deployment only relevant to Better-PaaS?
No. blue-green deployment appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
