Introduction to Pulumi: Infrastructure as Real Code

Pulumi lets you write infrastructure as actual code – TypeScript, Python, C#, Go. No DSL to learn. Here’s why it’s worth considering.

Why Pulumi?

• Use your existing programming language
• Full IDE support (IntelliSense, refactoring)
• Reuse patterns with functions, classes, packages
• Test infrastructure code with regular testing frameworks

TypeScript Example

import * as azure from "@pulumi/azure-native";

// Create resource group
const resourceGroup = new azure.resources.ResourceGroup("rg");

// Create storage account
const storageAccount = new azure.storage.StorageAccount("storage", {
    resourceGroupName: resourceGroup.name,
    sku: { name: "Standard_LRS" },
    kind: "StorageV2",
});

// Export the connection string
export const connectionString = storageAccount.primaryEndpoints.blob;

C# Example

var resourceGroup = new ResourceGroup("rg");

var storageAccount = new StorageAccount("storage", new StorageAccountArgs
{
    ResourceGroupName = resourceGroup.Name,
    Sku = new SkuArgs { Name = "Standard_LRS" },
    Kind = "StorageV2"
});

return new Dictionary<string, object?>
{
    ["connectionString"] = storageAccount.PrimaryEndpoints.Apply(e => e.Blob)
};

Terraform vs Pulumi

• Terraform: Stable, huge community, HCL learning curve
• Pulumi: Real code, smaller community, native cloud providers
