Learn PULUMI with Real Code Examples

Enables infrastructure provisioning using code rather than declarative templates.

Supports multiple cloud providers including AWS, Azure, GCP, Kubernetes, and more.

Allows developers to leverage programming constructs like loops, functions, and abstractions for infrastructure.

Provides a unified model for managing both cloud and on-prem resources.

Integrates with CI/CD pipelines for automated provisioning and updates.

Resource abstraction for cloud services

Stack management for isolated environments

Dependency graph handling for infrastructure

Real-time diff and preview of changes

CLI and SDKs for multiple languages

Stack - isolated environment for infrastructure state

Resource - individual cloud or Kubernetes entity

Program - code defining infrastructure

Outputs - exposed values from a stack

Secrets - encrypted sensitive data

Pulumi.yaml - project configuration

Pulumi.<stack>.yaml - stack-specific configuration

index.ts / main.py / main.go - main infrastructure program

node_modules or virtual environment - SDK dependencies

tests/ - infrastructure tests or mocks

Write infrastructure code in supported language

Run pulumi preview to see changes

Run pulumi up to apply changes

Inspect stack outputs and monitor resources

Update or destroy infrastructure with pulumi update/destroy

Beginner: single cloud stack deployment

Intermediate: multi-service application on cloud

Advanced: multi-cloud deployments with abstractions

Expert: CI/CD-integrated automated provisioning

Enterprise: multi-team governance and policy enforcement

Pulumi vs Terraform: general-purpose language vs HCL DSL

Pulumi vs CloudFormation: multi-cloud vs AWS-specific

Pulumi vs Ansible: declarative vs imperative code

Pulumi vs CDK: SDK-based vs cloud-native libraries

Pulumi vs Chef/Puppet: IaC code vs configuration management
