What is Azure Container Apps? • Serverless platform to run containerized applications • Built on top of powerful open-source projects • Kubernetes | Envoy | Dapr | KEDA • Hides most of the complexicity from the customer Introduction

Why do we need another service for containers? • There is no serverless pricing-model for AKS • Kubernetes itself could become 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” Introduction

The new Azure landscape for containers* Introduction Azure WebApps for Containers Azure Container Instances Azure Container Apps Azure Kubernetes Service * Azure has more services that can run containers, however those are typically a bit more specialized

Ingress (Envoy) • Envoy (https://www.envoyproxy.io/) acts as Ingress controller for your workloads • Apps could be exposed to the internet • We can implement 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 Platform Capabilities

Microservice (with Dapr) • Dapr (Distributed Application Runtime) 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! Platform Capabilitites

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, • Container resource utilization e.g., CPU or memory • Scaling configuration is part of the overall deployment manifest Platform Capabilitites

Hello Azure Container Apps Demo

How to deploy workloads to Azure Container Apps • Containers can be consumed from any kind of container registry • Public and Private registries are supported • If necessary, authentication is supported via • Username and Password • System-Assigned or User-Assigned Managed Service Identity (MSI) Consuming Docker Images

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 • AzureRM provider support is tracked at https://github.com/hashicorp/terraform- provider-azurerm/issues/14122 • Azure CLI integration is available via extension Deployment and monitoring

Provision and Deploy Azure Container Apps Demo

Azure Monitor Integration • Seamless Azure Monitor integration • Container logs will be streamed to Azure Log Analytics Workspace (Azure Monitor) • Log Analytics workspace must 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 • … Observability

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 Observability
