This document provides an overview of Azure Container Apps. It discusses the different container options in Azure, including Container Instance, App Service, Kubernetes Service, and Kubernetes on VMs. It presents Container Apps as a simpler option compared to Kubernetes that provides auto-scaling and other capabilities without managing a Kubernetes cluster. The rest of the document demonstrates Container Apps features like environments, containers, revisions, Dapr for microservice management, and KEDA for auto-scaling. It provides pricing information and the presenter's wish list for future Container Apps capabilities. In summary, the presenter believes Container Apps is a promising evolution from Container Instance but not yet production ready.

- 2. AGENDA Use Cases & Capabilities Which Tool and Why? A Simple Example Dapr Inter-Service Communication Scaling 2021 Azure Container Apps 2
- 3. ABOUT MYSELF • Software Architect, focus on scalable cloud solutions • Software Development background (App Dev) • Dad • Gamer and Hobbyist • Wisconsin Sports Fan (don’t @ me) 2021 Azure Container Apps 3
- 4. CONTAINER OPTIONS IN AZURE Azure Container Instance - Simple solution for deploying containers with a fixed scaling need - Does not support auto scaling or changing scale without recreating the service (downtime) - Assumes ingress (must expose a port), so it is clunky to run headless jobs Azure App Service - Easily launch and deploy HTTP-oriented services in containers - Built for HTTP based solutions - Allows Slot deployments for Green/Blue - Replication control (1 app instance per node, per-site scaling options) - Supports auto-scale based on Azure Monitor metrics across the whole 2021 Azure Container Apps 4
- 5. CONTAINER OPTIONS IN AZURE Azure Kubernetes Service - Cluster-as-a-service - Microsoft manages the master nodes, worker nodes size/scale defined by you - Tight-integration with Azure services such as application gateway, monitor, identity, etc. - Auto scale options across nodes, access to K8s based scaling options for apps Kubernetes on VMs - Bring-your-own-solution, run on Azure IaaS 2021 Azure Container Apps 5
- 6. PROBLEM STATEMENT Why Container Apps? Why Now? • More capabilities than Azure Container Instance • Less involved than Azure Kubernetes Service (AKS) • FAR less involved than rolling your own Kubernetes on VMs 2021 Azure Container Apps 6
- 7. WHY SHOULD WE CONSIDER AZURE CONTAINER APPS? Azure Container Apps provides turn-key microservice solutions, on-par with a high performing Kubernetes solution, at scale, and without the need to deal with any Kubernetes cluster management 2021 Azure Container Apps 7
- 8. 2021 Azure Container Apps 8 Container Instance App Service Kubernetes Service Kubernetes on VMs Simple Less Flexible Fewer Options Complex More Flexible Most Options
- 9. 2021 Azure Container Apps 9 Container Instance App Service Kubernetes Service Kubernetes on VMs Container Apps Simple Less Flexible Fewer Options Complex More Flexible Most Options
- 10. AZURE CONTAINER APPS Don’t worry about a k8s cluster Like Azure Container Instance, you just deploy the containers you want. There’s no cluster to worry about. Blue-Green by default More options for scaling your instances out than on Azure App Service with KEDA. Access to microservice management toolchain Like AKS, Optional access to microservice management toolchain Dapr. gRPC or HTTP for internal service communication is available. 2021 Azure Container Apps 10 No downtime required for any deployment or scaling operation Auto-scaling with greater depth

- 16. WHAT IS DAPR? Service Discovery / Service Invocation Services register with Dapr and become discoverable via Dapr’s API which is available to the container. Services can be directly invoked by calling the Dapr API as a proxy to the service State Storage Dapr has a full arsenal of state storage options, including Blob, Sql Server, Redis, and many more Pub/Sub Program against a pub/sub model 2021 Azure Container Apps 16 https://docs.dapr.io/reference/components- reference/supported-pubsub/ https://docs.dapr.io/reference/components- reference/supported-state-stores/ And many other solutions… Actors, Observability, Secret Management, Rate Limits, Authorization, others…

- 22. THIS IS IN PREVIEW! KEN’S WISH LIST I need these • Azure Monitor / Metrics • Provisioning Diagnostics • KEDA / Dapr diagnostics • A little more portal observability • Clarity on Idle pricing vs Active pricing I guess I could live without these, for a while • Custom Domains / Hostname Binding TLS / Cert Management • Virtual Network Integration (Private Endpoint) • Managed Identity • Bash / Shell Container access It’d be sweet if I could have these • Key Vault Integration • Bicep definitions • Scaling interval/cooldown access Here’s a list of features you’ll find in other container products in Azure, but are not yet available in Azure Container Apps
- 23. IN SUMMARY Looks REALLY promising. Cool stuff Love the evolution from Container Instance (ACI) Love the middle ground approach Not production ready just yet 2021 Azure Container Apps 23
