Deploying a Vaadin Application to Azure Cloud
This tutorial shows you how to deploy a Vaadin application to Microsoft’s Azure cloud using the traditional App Service, that works well for most typical Vaadin applications. If you have specific requirements, Azure has several other options to host Vaadin applications, such as raw virtual machines, and Container Apps (which are used in the tutorial). Azure also has great Kubernetes support.
Azure offers a 30-day free trial that includes 12 months of free commercial services. You can find details of their free and commercial services on the Azure website.
