Once upon a time ... and it‘s still 1 The company, the legacy software application 2 Introduction Omg, what do we need to do? Why do we need to migrate to the cloud?

Patrick Koch | | 22 June 2023 | / 6 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 “A legacy system is outdated computing software and/or hardware that is still in use.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?

Patrick Koch | | 22 June 2023 | / 8 Public Traditional use case: the engine test bed

Patrick Koch | | 22 June 2023 | / 9 Public Data processing with AVL CONCERTO

Public The cloud migration journey starts…

Patrick Koch | | 22 June 2023 | / 11 Public An evolution happens – why even more automation, and more data? 2021 .. 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

Patrick Koch | | 22 June 2023 | / 13 Public Cloud Migration Strategy Pain Point 1

Patrick Koch | | 22 June 2023 | / 14 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

Patrick Koch | | 22 June 2023 | / 15 Public Pain Point 2 Starting with a too complex implementation

Patrick Koch | | 22 June 2023 | / 16 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)”

Patrick Koch | | 22 June 2023 | / 17 Public The goal of the first implementation Azure Container Registry Azure Kubernetes Service Azure Virtual Machine Azure File Share Container 1 2 3 4

Patrick Koch | | 22 June 2023 | / 18 Public The faults 1. ACR not properly attached with AKS 2. Missing statements in Workload 3. Wrong Firewall Settings

Patrick Koch | | 22 June 2023 | / 19 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

Patrick Koch | | 22 June 2023 | / 20 Public The faults 1. ACR not properly attached with AKS 2. Missing statements in Workload 3. Wrong Firewall Settings

Patrick Koch | | 22 June 2023 | / 21 Public Start lightweight: use e.g. a Serverless Service Azure Container Instance

Patrick Koch | | 22 June 2023 | / 22 Public Pain Point 3 Manual Provisioning

Patrick Koch | | 22 June 2023 | / 23 Public Manual Provisioning of the resources e.g.: Creating a Kubernetes Cluster in Azure Can you reproduce your environment after the destruction?

Patrick Koch | | 22 June 2023 | / 24 Public Use Infrastructure as Code Approach Terraform Configuration File Azure Kubernetes Service

Patrick Koch | | 22 June 2023 | / 25 Public Pain Point 4 Costs

Patrick Koch | | 22 June 2023 | / 26 Public

Estimate the costs using tools

Patrick Koch | | 22 June 2023 | / 28 Public Automation – Establish Pipelines Terraform Configurations Azure Azure DevOps Pipeline • Create pipelines for conducting the Terraform commands • Controlled way of provisioning/destroying the resources • Everyone can trigger the pipeline

Patrick Koch | | 22 June 2023 | / 29 Public Automation – Establish Pipelines • Create pipelines for conducting the Terraform commands • Controlled way of provisioning/destroying the resources • Everyone can trigger the pipeline Video source: Azure Portal

Patrick Koch | | 22 June 2023 | / 30 Public The result of the first implementation

Patrick Koch | | 22 June 2023 | / 31 Public Conclusion Decide for a cloud migration strategy first Start lightweight with your first implementation Use an Infrastructure as Code approach Increase your automation
