About mid-April, the Azure Container Apps team announced a public preview of a new hosting plan and pricing structure for hosting your Container Apps. By default, there was a Serverless consumption hosting plan which you can use to host your Container Apps. This provided support for scale-to-zero scenarios and you’d only pay for resources that your application would use. With the Dedicated hosting plan now in preview, you still have the option of having a fully managed environment for hosting your Container Apps with scale-to-zero capabilities, but in addition to this you can also run applications with customized hardware using Dedicated workload profiles. ...

Azure Container Apps manages automatic horizontal scaling through declarative scaling rules. We can scale out our container apps based on a variety of different scalers. I recorded a video over the weekend covering how scaling works in Azure Container Apps, what KEDA is and how to set scaling rules within Azure Container Apps, using HTTP and Azure Queue storage scale rules as an example. If you prefer reading rather than watching, continue reading this post. I’ll only be covering the storage queue scaler in this post, so if you want to see how the HTTP scaler works, please watch the video. ...

Azure Kubernetes Service (AKS) simplifies deploying a managed Kubernetes cluster into Azure by offloading the operational overhead to Azure. Azure Container Registry allows you to build, store and manage container images in a private registry, from which you can pull your images into your AKS cluster. Azure Container Registry integrates with AKS. We can attach container registries to our AKS clusters using an Azure Active Directory managed identity. We can then assign that managed identity will the AcrPull role assignment that allows our AKS cluster to pull images from our Azure Container Registry. ...

Azure Container Apps is a serverless container platform that we can use to run microservices and containerized applications without having to worry about managing complex infrastructure and container orchestrations. In this video, I introduce the key concepts and features of Azure Container Apps and go through a demo on how you can create a simple Container App using Bicep. If you have any question about this video or Azure Container Apps in general, feel free to comment below or reach out to me on Twitter. ...
