3. Azure infrastructure as code Azure Resource Manager - is a consistent management layer which allows to work with separate resources as a group, in a single, coordinated operation. Background Azure Resource Manager, or ARM, is the primary deployment type for Azure Replaces the classic Azure Service Manager (ASM) model; aka “Azure v1” Used across cloud environments, including: Public (Azure), Sovereign (Gov Cloud), and Private (Azure Stack) The ARM model lets you state "Here is what I intend to create" without having to write the sequence of programming commands to create it. Azure Resource Manager template - A JavaScript Object Notation (JSON) file that defines one or more resources to deploy to a resource group. It also defines the dependencies between the deployed resources. The template can be used to deploy the resources consistently and repeatedly.

5. Azure infrastructure as code ( IaC ) Understanding ARM Template

6. ARM Template Tools we can use Visual Studio Visual Studio Code Terraform, Azure Building Blocks, Ansible, etc. Configuration via Azure Automation DSC (aka PowerShell DSC), IaaS VM Custom Script Extension, Puppet, Chef, Salt Stack Visualize with ARMViz NotePad ++

7. ARM Template Core Structure { "$schema" : "https://schema.management.azure.com/schemas/2015-01-01/ deploymentTemplate.json #" , "contentVersion" : "1.0.0.0" , "parameters" : {}, "variables" : {}, "resources" : [], "outputs" : {} }

8. ARM Template Core Structure The allowed types for values are: String or secureString – any valid JSON string int – any valid JSON integer bool – any valid JSON Boolean object – any valid JSON object array – any valid JSON array

9. ARM Template Parameters "parameters" : { " storageAccountType " : { "type" : "string" , " defaultValue " : " Standard_LRS " , " allowedValues " : [ " Standard_LR S " , " Standard_GRS " , " Standard_ZRS " , " Premium_LRS " ], "metadata" : { "description" : "Storage Account type" } } , " storageAccountName " : { "type" : "string" , " defaultValue " : "azureglobalbootcamp2018" , " maxlength " : 24 , "metadata" : { " description" : "The name of the Storage Account" } } In the parameters section of the template, you specify which values you can input when deploying the resources

10. ARM Template Parameters file { "$schema": " http://schema.management.azure.com/schemas/201501-01/ deploymentParameters.json #", "contentVersion": "1.0.0.0", "parameters": { “ winServerEdition ": { "value": “2012-R2-Datacenter" }, " adminUsername ": { "value": “ vmAdmin " } } } In the parameters section of the template, you specify which values you can input when deploying the resources

11. ARM Template variable "variables": { " storageName ":"[ concat ( toLower (parameters(‘prefix’)), resourceGroup ().id)]“, " environmentSettings ": { "test": { " instanceSize ": "Small", " instanceCount ": 1 }, "prod": { " instanceSize ": "Large", " instanceCount ": 4 } } } In the variables section, you construct values that can be used throughout your template.

12. Azure infrastructure as code ( IaC ) Used across Public (Azure), Sovereign (Gov Cloud), and Private (Azure Stack) Obtain more granularity, tagging, RBAC Repeatable, templated deployments (including dependencies) Remember the Best Practices Metadata Descriptive Names pascalCasing Impose restrictions (i.e. MinLength , AllowedValues , etc.) Use Variables Do not store sensitive information in the parameters file (i.e. the Local Admin password)
