ForgeRock Blue-Green Deployment is a strategy using two identical production environments to minimize downtime during upgrades. This method allows you to deploy new versions of your application with minimal risk and disruption to your users. What is Blue-Green Deployment? Blue-Green Deployment involves running two identical production environments, referred to as “blue” and “green.” While one environment (blue) handles live traffic, the other (green) is idle. After deploying updates to the green environment and validating them, you switch traffic from blue to green. This process ensures that there is always a stable environment available to handle requests, thus minimizing downtime. ...
