SAP Dev/Test & Automation in Azure Ross Sponholtz Principal Program Manager, Azure CAT

So, what is SAP Dev & Test? Dev & Test environment managed by IT Developer Workstation A workstation with IDE and role specific/project-specific tools installed to be productive. Team Collaboration Environment Development teams collaboratively design, develop and deploy applications using developer and lifecycle management services. Dev & Test environment managed by IT Pre-prod Environments Developers and teams need pre-production environments for development, integration, user acceptance testing and QA. Production Support For supporting the production environments, teams often have a duplicate “production support” environment for testing.

Dev/Test Scenarios drive Azure Consumption

Why is Dev/Test an easy workload win 50% of infrastructure is used for dev- test environments 65% of developers say it is too complicated and time-consuming to get development and test resources 10% Average utilization of dedicated dev-test infrastructure Security/Compliance is a lesser concern Dev/Test != “Developers spinning up VMs for development” Dev/Test = Dev + Test + Staging + QA + .. = “non-production”

Myth: Dev/Test is a low consumption workload 11/10/2018 6:19 AM 2 2 Myth: Dev/Test is a low consumption workload Share Point Dev/Test in Azure 53% cost savings1 Azure Services included in scenario 55 VMs: 20 medium, 22 extra large, 13 A7 35 TB LR storage 35 TB zone 1 egress, 5 VPN connections Azure Cost Breakdown Annual Azure VMs expense $172,071 Annual storage expense $21,462 Annual egress expense $36,792 Annual admin expense $6,110 Annual other expenses $1,599 Total $238,034 On-premises DC Cost Breakdown Annual hardware expense $371,774 Annual software expense $89,200 Annual power expense $10,913 Annual administration costs $11,638 Annual DC facility expenses $27,166 Total $510,691 Note: Assumptions have been sourced from public data sources including www.dell.com and www.hp.com and third party reports including Simpson, Nik. “Counting the cost of the Elephant in the Data Center.” Burton Group (2009). The savings quoted in the slides are actually quite conservative (e.g., we assume on-premises infrastructure is 100% utilized, assume a very power-efficient on-premises data center).

Deploying SAP Test/Dev in Azure

Deploying HANA from SAP Cloud Appliance Library to Microsoft Azure https://cal.sap.com/

Automation of SAP on Azure Address the multitude of environments Need for environments with identical infrastructure Remove the potential for human error in configuration process Allow environments to be created and removed easily

Automation Technologies Azure Resource Group Templates Desired State Configuration (DSC) Puppet/Chef Azure script extensions

What is an ARM Template? Artifacts (optional depending on resources) JSON files – “Infrastructure-as-Code” Artifacts (optional depending on resources) Configuration files to apply to resources Examples: Desired State Configuration (DSC) Script and DSC Resources Also “Infrastructure-as-Code” Web Deployment Packages

Arm template basic format "resources": [ { "apiVersion": "2016-01-01", "type": "Microsoft.Storage/storageAccounts", "name": "mystorageaccount", "location": "westus", "sku": { "name": "Standard_LRS" }, "kind": "Storage", "properties": { } }] PUT https://management.azure.com/subscriptions/{s ubscriptionId}/resourceGroups/{resourceGroupN ame}/providers/Microsoft.Storage/storageAccou nts/mystorageaccount?api-version=2016-01-01 REQUEST BODY{ "location": "westus", "properties": { } "sku": { "name": "Standard_LRS" }, "kind": "Storage" } API Explorer: https://azure.github.io/projects/apis/ All resources descriptions have apiversion, type, name, location

DSC for Azure Declarative configuration of the virtual machine Windows Features and Roles Custom application configuration

Desired State Configuration Configuration Main { Param ( [string] $nodeName ) Import-DscResource -ModuleName PSDesiredStateConfiguration Node $nodeName { WindowsFeature WebServerRole { Name = "Web-Server" Ensure = "Present" } Package InstallWebDeploy { Path = "C:\WindowsAzure\WebDeploy_amd64_en-US.msi" Name = "Microsoft Web Deploy 3.6" ProductId = "{ED4CC1E5-043E-4157-8452-B5E533FE2BA1}" Arguments = "ADDLOCAL=ALL" Service StartWebDeploy { Name = "WMSVC" StartupType = "Automatic" State = "Running" DependsOn = "[Package]InstallWebDeploy"

Puppet Puppet Master contains repository of configurations Agent nodes register with Puppet Master, receive their specific configuration Puppet runs configuration code, similar to DSC
