Scaling .Net containers with event-driven workloads

Scaling .Net containers with event-driven workloads

Slide deck related to the talk presented at Surati Tech Talks 2022 event on 10th January 2022. Demonstrates the power of Kubernetes along with Kubernetes-based Event Driven Autoscaing (KEDA) project to support event driven workloads. Microsft Azure is used as the cloud platform with managed Azure Kubernetes Service (AKS) as target environment

  4. AGENDA ▸ Scaling options with Kubernetes ▸ KEDA overview ▸

    TechTalks demo with RabbitMQ ▸ Autoscaling with KEDA ▸ KEDA Architecture 4
  5. Pre-requisites • Self contained application with all its dependencies Docker

    • Orchestrates containers • Self healing • Service discovery • Scaling Kubernetes • Dockerhub / private container registry • Repository for storing container images Container Registry • Managed Kubernetes service on Azure • Native integration with other Azure services like Azure Active Directory (AAD), Azure Container registry (ACR), Azure Container Instances (ACI), Azure Monitor etc. Azure Kubernetes Service (AKS)

  8. @nileshgule TechTalks Producer setup https://github.com/NileshGule/pd-tech-fest-2019  Techtalks producer .Net Core

    API  2 replicas  Exposed as Kubernetes service using LoadBalancer
  9. @nileshgule TechTalks Consumer setup https://github.com/NileshGule/pd-tech-fest-2019  Techtalks consumer .Net Core

    exe  Not exposed outside Kubernetes cluster  Consumes configured number of messages in a batch
  10. @nileshgule RabbitMQ setup https://github.com/NileshGule/pd-tech-fest-2019  RabbitMQ deployed using Helm chart

     Exposed as Kubernetes service
  11. @nileshgule TechTalks Demo setup 1000 (configurable) messages Batch of 50

  22. Summary ▸ Single purpose lightweight component ▸ Any Kubernetes cluster

    (1.16+) ▸ Extends Kubernetes with event driven capabilities ▸ No overwriting or duplication of existing functionalities ▸ Maps an event source to Deployment, StatefulSet, Custom Resource or Job for scaling ▸ Flexible and safe to run alongside any other Kubernetes framework or application ▸ Support 45+ auto scalers out of the box 25
