Explanation

An Azure Container Apps environment includes a scalable edge ingress proxy responsible for the following features: * Transport Layer Security (TLS) termination *-> Load balancing and traffic splitting between active container app revisions. Having control over where you direct incoming traffic allows you to implement patterns like blue-green deployment and conduct A/B testing. * Session affinity, Blue-green deployment in Azure Container Apps The container app must have the configuration.activeRevisionsMode property set to multiple to enable traffic splitting. Note: Blue-Green Deployment is a software release strategy that aims to minimize downtime and reduce the risk associated with deploying new versions of an application. In a blue-green deployment, two identical environments, referred to as "blue" and "green," are set up. One environment (blue) is running the current application version and one environment (green) is running the new application version. Once green environment is tested, the live traffic is directed to it, and the blue environment is used to deploy a new application version during next deployment cycle. https://learn.microsoft.com/en-us/azure/container-apps/blue-green-deployment https://learn.microsoft.com/en-us/azure/container-apps/ingress-environment-configuration
