Public Today’s Agenda 3 2 Who is this guy? Introduction 1 Once upon a time ... and it‘s still What happened before the cloud? Omg, what do we need to do? Why do we need to migrate to the Cloud? Conclusion 5 The Pain Points Of course we didn‘t avoid making embarrassing mistakes ;) 4 Q&A 6

Public Introduction

Public Who am I? @PK_Koch patkoch87 patrickkoch.dev Graz (Austria) DevOps Engineer Patrick Koch Icon sources: icons8.de

Public AVL List GmbH Founded 1948 More than 11,000 worldwide 4,000 in Graz (headquarters) 45 affiliates worldwide Export quota of 97% AVL List GmbH (“AVL”) is the world’s largest independent company for development, simulation and testing in the automotive industry, and in other sectors. Drawing on its pioneering spirit, the company provides concepts, solutions and methodologies to shape future mobility trends.”

Public Evolved to platform product Container, K8s Automation Framework Web components Started > 25 years ago Python support REST interface 2014 New Generation (unmanaged legacy (C++) and managed (C#) code). Windows® application (component & full integration in internal products) 2018 ~ 8200 files ~ 2,9 Mio LOC Linux components (data, Python) 2022 ... “A legacy system is outdated computing software and/or hardware that is still in use. ” ~ 800 customers ~ 23000 users The application to migrate in the cloud: AVL CONCERTO

Public Once upon a time ... What happened before the
cloud?

Public Traditional Use Case: The Engine Test Bed

Public Data Processing Use Case

Public Why do we need to migrate to the cloud…

Public An evolution happens – why even more automation? 2021 .. ~ 30 years Huge testbed for single unit under test (UUT) 1 Operator per testbed Very high costs Exchanging of unit is labour-intesive One testing unit for multiple UUTs (Battery Cells) 1 Operator for whole lab Costs per UUT are much lower UUT exchange works automated 2021 ..

Public The Pain Points

Public Cloud Migration Strategy Pain Point 1

Public Cloud Migration Strategy Decide for a strategy before starting the implementation Lift & Shift (Rehost) Whole application is taken and pushed into container not possible / would cause to much costs Refactoring Rebuild

Public Pain Point 2 Starting with a too complex implementation

Public Lift and shift to container using Azure Kubernetes Service Source: https://docs.microsoft.com/de-de/azure/architecture/solution-ideas/articles/migrate-existing-applications-with-aks “Easily migrate existing application to container(s) and run within the Azure managed Kubernetes service (AKS)”

Public The goal of the first implementation Azure Container Registry Azure Kubernetes Service Azure Virtual Machine Azure File Share Container running Concerto 1 2 3 4

Public The faults 1. ACR not properly attached with AKS 2. Missing statements in Workload 3. Wrong Firewall Settings

Public The faults 1. ACR not properly attached with AKS 2. Missing statements in Workload 3. Wrong Firewall Settings nodeSelector: kubernetes.io/os: windows tolerations: - key: "kubernetes.io/os" operator: "Equal" value: "windows" effect: "NoSchedule" restartPolicy: Never backoffLimit: 4

Public The faults 1. ACR not properly attached with AKS 2. Missing statements in Workload 3. Wrong Firewall Settings

Public Start lightweight: use e.g. a Serverless Service Azure Container Instance

Public Pain Point 3 Manual Provisioning

Public Manual Provisioning of the resources e.g.: Creating a Kubernetes Cluster in Azure Can you reproduce it after destroying it?

Public Use Infrastructure as Code Approach Terraform Configuration File Azure Kubernetes Service

Public Pain Point 4 Costs

Public

Public Estimate the costs using tools

Public Automated Resource Provisioning in Azure with ADO Pipelines and Terraform Terraform Configurations State Files .tf .tfstate Azure Subscription ADO Pipeline

Public Conclusion Decide for a Cloud Migration Strategy Avoid to start with a too complex implementation – start lightweight Don‘t do manual provisioning – use Infrastructure as Code approach Be aware of the costs, monitor them
