20. @hossambarakat_
    • Pulumi is an open source infrastructure as code tool
    the lets you use real languages – C#, TypeScript,
    Go,… – to provision and manage cloud resources.

21. @hossambarakat_
    • Control flow with loops and if conditions
    • Abstraction with functions, classes, packages,…
    • Code sharing with package management (Nuget,
    npm,…)
    • Authoring with favourite IDEs, refactoring, code
    completion, static type checking
    • Testing with existing frameworks and tools
    Benefits

    Terraform vs Pulumi
    var resourceGroup = new ResourceGroup("pulumi-resources",
    new ResourceGroupArgs
    {
    Location = "West Europe"
    });
    );
    var environments = new string[]{"dev", "uat", "prod"};
    foreach (var environment in environments)
    {
    var storageAccount = new Account($"storage{environment}",
    new AccountArgs
    {
    Name = $"iacpulumi{environment}",
    ResourceGroupName = resourceGroup.Name,
    Location = resourceGroup.Location,
    AccountReplicationType = "LRS",
    AccountTier = "Standard",
    });
    }
    resource "azurerm_resource_group" "rg" {
    name = "terraform-resources"
    location = "West Europe"
    }
    variable "environments" {
    description = "storage account regions"
    type = list(string)
