Pulumi vs. Terraform: Why Software Engineers are Switching

Introduction

For years, HashiCorp Terraform and HCL have dominated the Infrastructure as Code domain. However, many software engineers are pushing back against the constraints of domain-specific markup languages. Pulumi answers this friction by allowing developers to manage cloud infrastructure using standard programming languages like TypeScript, Python, Go, and C#.

Pulumi TypeScript Example

import * as aws from "@pulumi/aws";

const createInfrastructure = true;

if (createInfrastructure) {
    for (let i = 0; i < 3; i++) {
        new aws.s3.Bucket(`my-app-bucket-${i}`);
    }
}

Conclusion

While Terraform remains an exceptionally reliable and battle-tested choice, Pulumi is rapidly carving out a massive footprint among engineering organizations that prioritize deep testing models and software engineering patterns over plain markup configurations.
