Zero Downtime Deployments with Azure PaaS

The DevOps Lab

How can I deploy my applications to Azure Platform-as-a-Service (PaaS) like Azure Kubernetes Service (AKS) without having any downtime? How can I automate this, and how can I ensure my customers won't notice changes are happening? In this interview, you can see Damian chat with Marcel de Vries about how to use Azure DevOps Build and Release pipelines to deliver your application to production many times a day while not interrupting your users.
