Pulumi is an open-source infrastructure as code (IaC) tool that enables you to define, provision, and manage cloud infrastructure using familiar programming languages like Python, TypeScript, JavaScript, Go, .NET, and Java. It bridges the gap between traditional IaC tools and modern cloud development practices, offering flexibility, productivity, and collaboration benefits.

• **Multi-Language Support:** Pulumi lets you define your infrastructure using popular programming languages, allowing you to leverage your existing skills and tools.
• **Cloud-Agnostic:** Pulumi supports major cloud providers like AWS, Azure, Google Cloud, and Kubernetes, providing flexibility and avoiding vendor lock-in.
• **State Management:** Pulumi automatically tracks the state of your infrastructure, enabling you to preview changes before applying them and facilitating easy rollbacks.
• **Modularity and Reusability:** Pulumi encourages the use of modular and reusable components, simplifying infrastructure management and promoting best practices.
• **Collaboration:** Pulumi's cloud backend and collaboration features enable teams to work together effectively on infrastructure projects.

• **Developer-Friendly:** Pulumi's use of familiar programming languages makes it accessible to developers, reducing the learning curve associated with traditional IaC tools.
• **Flexibility:** The ability to use different programming languages and support for multiple cloud providers offers flexibility in choosing the best tools and platforms for your infrastructure.
• **Productivity:** Pulumi's automation and code reusability features help improve productivity and accelerate infrastructure provisioning.
• **Collaboration:** The cloud backend and collaboration features streamline teamwork and facilitate knowledge sharing.
• **Strong Ecosystem:** Pulumi integrates with various tools and services, enhancing its capabilities and providing a rich ecosystem for infrastructure management.

1. **Creating an AWS S3 Bucket (TypeScript):**

```typescript import * as aws from “@pulumi/aws”;

const bucket = new aws.s3.Bucket(“my-bucket”); ```

2. **Deploying a Kubernetes Deployment (Python):**

```python import pulumi import pulumi_kubernetes as k8s

app_labels = { “app”: “nginx” } deployment = k8s.apps.v1.Deployment(“nginx”,

   spec={
       "selector": { "match_labels": app_labels },
       "replicas": 1,
       "template": {
           "metadata": { "labels": app_labels },
           "spec": {
               "containers": [{
                   "name": "nginx",
                   "image": "nginx:latest",
                   "ports": [{ "container_port": 80 }]
               }],
           }
       }
   })

3. **Provisioning an Azure Resource Group (C#):**

```csharp using Pulumi; using Pulumi.AzureNative.Resources;

var resourceGroup = new ResourceGroup(“my-resource-group”, new ResourceGroupArgs {

   Location = "West US"

These examples demonstrate how Pulumi allows you to define infrastructure using code in different programming languages, simplifying provisioning and management across various cloud platforms.
