Patrick Koch AVL List GmbH (Headquarters) Public Common Cloud Migration Pain Points and how to overcome them based on practical experience

Today’s Agenda 3 What happened before the cloud? Once upon a time ... and it‘s still 1 Who is this guy? 2 Introduction 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 Once upon a time ... What happened before the cloud?

No content

Data Processing with the Desktop Application

Why do we need to migrate to the cloud…

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 ..

The Pain Points

Cloud Migration Strategy Pain Point 1

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

Pain Point 2 Starting with a too complex implementation

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)”

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

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

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

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

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

Pain Point 3 Manual Provisioning

Manual Provisioning of the resources e.g.: Creating a Kubernetes Cluster in Azure Can you reproduce your environment after the destruction?

Use Infrastructure as Code resource "azurerm_resource_group" "example" { name = "example-resources" location = "West Europe" } resource "azurerm_kubernetes_cluster" "example" { name = "patricks-aks" location = azurerm_resource_group.example.location resource_group_name = azurerm_resource_group.example.name dns_prefix = "exampleaks1" default_node_pool { name = "default" node_count = 1 vm_size = "Standard_D2_v2" } Terraform Configuration Azure Kubernetes Service

Pain Point 4 Costs

No content

Estimate the costs using tools

Automated Resource Provisioning in Azure with ADO Pipelines and Terraform Terraform Configurations Azure Azure DevOps Pipeline

Data Processing using an automated way in Azure

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 Monitoring of the costs, increase the automation
