Azure Container Apps: Endlich Serverless?!

Mit Azure Container Apps können Sie Container-basierte verteilte Anwendungen professionell in der Cloud betreiben, ohne sich selbst um den darunterlegenden Kubernetes kümmern zu müssen. Einfach und professionell zu automatisieren, ein konkurrenzfähiges Feature-Set, und dennoch einfach zu bedienen! Das ist das Versprechen, das Microsoft gibt.

Besuchen Sie diesen Vortrag von Thorsten Hans und lernen Sie Azure Container Apps kennen! Gemeinsam werden wir unterschiedliche Anwendungstypen bereitstellen, dienstspezifische Features einsetzen, Provisionierung und Deployment automatisieren, um festzustellen, ob das Versprechen von Microsoft eingehalten wurde. Am Ende des Vortrages haben Sie einen Überblick über das Leistungsspektrum von Azure Container Apps und können einschätzen, ob Ihre Anwendung dank Azure Container Apps Serverless betrieben werden kann, wodurch Sie um die Administration eines eigenen Kubernetes-Clusters herumkommen.

4. • Introduction • Azure Container Apps Capabilities • Hands-On Azure Container Apps • Inner-Loop performance with Azure Container Apps • Conclusion Agenda
5. 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
6. Why do we need another service for containers? • There is no serverless pricing-model for AKS • Kubernetes itself 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” Introduction
7. The new Azure landscape for containers* Introduction Azure WebApps for Containers Azure Container Instances Azure Container Apps Azure Kubernetes Service * Azure offers more services that can run containers, however those are typically more specialized

13. Supported types of apps Azure Container Apps Capabilities https://learn.microsoft.com/en-us/azure/container-apps/overview
14. 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 Azure Container Apps Capabilities
15. 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! Azure Container Apps Capabilitites
16. 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 60+ 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 Azure Container Apps Capabilitites

20. 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) Hands-On Azure Container Apps
21. 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 supports Container Apps since January 2023 • Azure CLI integration is available via extension Hands-On Azure Container Apps
22. Provision and Deploy Azure Container Apps Demo
23. 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 Hands-On Azure Container Apps
24. 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 Troubleshooting
