Migrating to Pulumi from CloudFormation

Increase productivity with programming languages

AWS CloudFormation provides a configuration DSL for you to describe and provision infrastructure resources on AWS.

Pulumi enables you to describe the same infrastructure resources as real code, providing huge productivity gains, while decreasing the brittleness of YAML-based configuration files.

The benefits of using Pulumi

Tame cloud complexity

Deliver infrastructure from 50+ cloud and SaaS providers. Pulumi’s SDKs provide a complete and consistent interface that offers full access to clouds and abstracts complexity.

Bring the cloud closer to application development

Build reusable cloud infrastructure and infrastructure platforms that empower developers to build modern cloud applications faster and with less overhead.

Use engineering practices with infrastructure

Use engineering practices with infrastructure” to: “Replace inefficient, manual infrastructure processes with automation. Test and deliver infrastructure through CI/CD workflows or automate deployments with code at runtime.

Foster collaboration and innovate faster

Unite infrastructure teams, developers, and security teams around shared languages and tools so that everyone can ship products quickly and reliably.

Creating a Simple Web Server on AWS

In this example, we use JavaScript to create a simple web server on AWS using EC2.

This code creates the necessary security group, deploys a very simple web server for example purposes, and then creates the instance, before exporting the IP and hostname.

Pulumi can be used on any resource on AWS, Azure, Google Cloud, Kubernetes, and OpenStack, covering serverless, containers, and infrastructure.

const aws = require("@pulumi/aws");

                    let size = "t2.micro";
                    let ami  = "ami-7172b611"

                    // Create a new security group for port 80.
                    let group = new aws.ec2.SecurityGroup("web-secgrp", {
                    ingress: [
                    { protocol: "tcp", fromPort: 22,
                    toPort: 22, cidrBlocks: [""] },
                    { protocol: "tcp", fromPort: 80,
                    toPort: 80, cidrBlocks: [""] },

                    // Create a simple web server.
                    let userData =
                    "#!/bin/bash \n" +
                    "echo 'Hello, World!' > index.html \n" +
                    "nohup python -m SimpleHTTPServer 80 &";

                    let server = new aws.ec2.Instance("web-server-www", {
                    tags: { "Name": "web-server-www" },
                    instanceType: size,
                    securityGroups: [ group.name ],
                    ami: ami,
                    userData: userData

                    exports.publicIp = server.publicIp;
                    exports.publicHostName = server.publicDns;

Featured Customer


Hyland, a blockchain SaaS company faced two challenges with their cloud infrastructure:

By moving to Pulumi, Hyland were able to solve both challenges with significant increases in capability:

25,000 Lines of CloudFormation reduced to 500 Lines of JavaScript
New customer provisioning time reduced from 3 weeks to 1 hour

Pulumi has given our team the tools and framework to achieve a unified development and DevOps model, boosting productivity and taking our business to any cloud environment that our customers need. We retired 25,000 lines of complex code that few team members understood and replaced it with 100s of lines in a real programming language.
