At 10:00 AM, you queue JobA.
JobA starts and runs for 10 minutes until 10.10 AM.
At 10:00 AM, you queue JobB.
JobB starts and runs for 20 minutes until 10.20 AM.
At 10:05 AM, you queue JobC.
At 10.05 AM there are no available job slots.
At 10.10 AM on slot is free. JobC starts to run at 10.10 AM.
Note: Make your deployment faster parallelizing your jobs in Azure ...
In Azure DevOps, parallel jobs are used to run multiple jobs simultaneously, speeding up pipeline execution. If you have more jobs than available parallel jobs, the extra jobs will be queued and run sequentially after the others complete. You can control how many jobs run in parallel, either through pipeline settings or by managing parallel job capacity within your organization.

You can check policy compliance with gates.
You can extend the approval process for the release by adding a gate. Gates allow you to configure automated calls to external services, where the results are used to approve or reject a deployment.
You can use gates to ensure that the release meets a wide range or criteria, without requiring user intervention.

Explanation:
Box 1: 7
All has triggers (manual and releases)
Box 2: Web Application Artifact
It does not have artifacts (build or code) to trigger automatic release process.

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.
