What is Azure Container Apps?
• Serverless platform to run containerized and cloud-native applications
• Built on top of battle-proven open-source projects
• Kubernetes
• Envoy
• Dapr
• KEDA
• Hides most of the complexicity from us as customers
Introduction

Why do we need yet another service for containers?
• There is no serverless pricing-model for Azure Kubernetes Service (AKS)
• AKS (and vanilla Kubernetes) is complex
• It’s hard to find, hire, and keep people that really know Kubernetes
• Azure Container Instances and Web App for Containers have some “glitches” and
“gotchas”

Ingress (Envoy)
• Envoy https://www.envoyproxy.io/ acts as Ingress controller for your workloads
• Apps could be exposed to the internet
• We can use traffic split (see SMI Spec) https://github.com/servicemeshinterface/smi-
spec/blob/main/apis/traffic-split/v1alpha4/traffic-split.md
• Apps hosted in the same environment, can interact with each other
• In this case, think of a regular Kubernetes service FQDN
myservice.mynamespace.svc.cluster.local

Microservice (with Dapr)
• Dapr https://dapr.io is part of Azure Container Apps
• Dapr simplifies building distributed application architectures
• Dapr components are injected automatically
• leveraging Kubernetes sidecar-pattern
• Dapr is 100% optional!

Autoscaling with KEDA (Kubernetes Event Driven Autoscaling)
• KEDA https://keda.sh allows you to scale workloads using scalers
• Scalers define scaling-behavior due to external or internal signals
• KEDA has 50+ built-in scalers like for example
• Azure Service Bus Queue, Redis, Apache Kafka, …
• Scaling configuration is part of the overall deployment manifest

Consuming Docker Images
• Containers can be consumed from any kind of Container registry
• Public and Private Container registries are supported
• Authentication is supported via
• Username and Password (or Tokens)
• System-Assigned or User-Assigned Managed Service Identity (MSI)

How to deploy Azure Container Apps
• Azure Container Apps are regular Azure Resource Manager (ARM) entities
• Azure Container Apps can be provisioned using
• Project Bicep
• Pulumi
• Terraform using the AzAPI provider
• finally, also available in the AzureRM provider (since January 2023)
• Azure CLI integration is available via extension

Observability
• Seamless Observability integration
• Container logs will be streamed to Azure Log Analytics Workspace (or Azure Monitor)
• Log Analytics workspace should be linked to the Azure Container App Environment
• Logging agents enrich logs written to STDOUT and STDERR with data like
• Container App Name
• Revision & Environment Name
• Container Image Repository & Tag

How to investigate and troubleshoot
• Query Log Analytics Workspace for individual logs
• Directly access log stream in your terminal or Azure Portal
• Shell access to containers using your terminal or Azure Portal
