Pulumi vs Terraform: Comparing Infrastructure as Code Tools

Are you tired of the high costs, manual errors, and non-scalable stacks that come with manually provisioning application infrastructure?

Are you tired of the high costs, manual errors, and non-scalable stacks that come with manually provisioning application infrastructure? If so, you’re not alone. As companies have expanded their infrastructure stacks, the need for a better solution has become increasingly apparent. Enter Infrastructure as Code (IaC), a paradigm that allows developers to define their infrastructure stacks using code, rather than relying on manual provisioning. Pulumi and Terraform are both infrastructure-as-code tools used for managing and deploying cloud infrastructure.

Two of the most popular IaC tools are Pulumi and Terraform. While they offer similar features to provision and manage virtual environments, it can be challenging to decide which one is right for your business. Terraform has long been the go-to choice for many organizations, but Pulumi is a newer, more modern solution that is quickly gaining popularity.

In this article, we’ll take a closer look at both Pulumi and Terraform, comparing and contrasting their features and capabilities. By the end, you’ll have a better understanding of the Pulumi vs Terraform debate and which tool might be the best fit for your organization’s infrastructure needs.

What is Pulumi?

Discover the future of Infrastructure as Code with Pulumi! This innovative open-source tool offers seamless design, deployment, and management of cloud resources across a variety of public, private, and hybrid cloud providers, including AWS, Azure, Google Cloud, Kubernetes, phoenixNAP Bare Metal Cloud, and OpenStack. Pulumi allows you to create and manage both traditional infrastructure elements like virtual machines and networks, as well as modern cloud components like containers, clusters, and serverless functions.

In DevOps, Infrastructure as Code is essential for ensuring scalable and testable infrastructure configurations. Pulumi makes configuring the DevOps pipeline a breeze, freeing up IT operations to focus on software development. Unlike Terraform, Pulumi doesn’t require you to learn a complex DSL, making it easier and faster to use. With Pulumi, you can use your existing programming skills to create, deploy, and manage a cloud infrastructure in your preferred programming language.

If you’re using AWS, Pulumi AWS provides high-level multi-cloud libraries and low-level fine-grained control of AWS-specific resources to get your code up and running on the AWS cloud quickly. Whether you’re a seasoned developer or just starting, Pulumi is the perfect choice for businesses looking to streamline their Infrastructure as Code process.

What is Terraform?

If you’re looking for a reliable Infrastructure as Code (IaC) tool to build, modify, and version virtual infrastructure, Terraform is one of the most widely-used options out there. It’s a declarative tool that allows you to define the desired final state of your infrastructure, and then automatically manages how to get there. With Terraform, you can easily provision low-level components like storage and networking, as well as higher-end resources like DNS entries, across multiple cloud providers. Plus, it offers a user-friendly interface and a consistent CLI workflow, making it a popular choice for many companies. If you want to learn more about how Terraform can help you streamline your cloud service management and deliver infrastructure as code, keep reading!

Pulumi vs Terraform: Which is the Better Infrastructure as Code (IaC) Tool for You?

In the world of infrastructure as code, Pulumi and Terraform are two widely used open-source tools. But how do they compare? In this article, we’ll dive into the differences between the two, helping you determine which one is the best fit for your needs.

To begin, both Pulumi and Terraform enable defining and deploying infrastructure as code. Terraform enforces guidelines and restrictions through its HCL language, whereas Pulumi makes use of language concepts like loops and classes, providing convenience for developers to design testing suites, use extensions and libraries.

When it comes to learning curve, Pulumi offers an easier start, since it allows you to use your preferred programming language to define infrastructure stacks. For instance, with Python, you can easily design an AWS DynamoDB table using Pulumi, as shown below:

import pulumi

import pulumi_aws as aws


attributes = {

“name”: “Id”,

“type”: “S”



with pulumi.Resource(“aws:dynamodb/table”, “ddb-table”,







In this version, the with statement creates a new aws:dynamodb/table resource called “ddb-table” with the specified arguments. The attributes argument is a dictionary created with the ** syntax to unpack the attributes keyword arguments. The pass statement is used to indicate that the resource definition is empty, since we don’t need to add any additional configuration beyond the arguments provided.

On the other hand, Terraform requires knowledge of HCL syntax, which is intuitive and relatively simple. Here’s an example of Terraform code for a DynamoDB table that’s similar to the Pulumi example:

provider “aws” {

region = “us-west-2”



resource “aws_dynamodb_table” “ddb_table” {

name           = “ddb-table”

billing_mode   = “PAY_PER_REQUEST”

hash_key       = “Id”

read_capacity  = 5

write_capacity = 5


attribute {

name = “Id”

type = “S”



This code creates an AWS DynamoDB table named “ddb-table” with a single string attribute named “Id”, and is configured to use the PAY_PER_REQUEST billing mode. The hash key is set to “Id”, and the read and write capacity is set to 5. The AWS provider is also specified with the “us-west-2” region.

While Pulumi offers a more seamless learning curve, learning HCL may still be valuable, as all Terraform files are formatted in HCL.

Both Pulumi and Terraform work with popular cloud providers and operating systems, but some IDEs may need an external plugin for Terraform. Pulumi provides advantages like code completion and automatic syntax correction.

Pulumi enables working with larger and more intricate infrastructure stacks in a modular way, making them more manageable over time. Ultimately, choosing between Pulumi and Terraform depends on individual requirements, and understanding the distinctions between the two tools can assist in making an informed decision.

How to use Pulumi with AWS?

As already discussed, Pulumi can help you get your code to the AWS cloud way faster than ever before. To be specific, Pulumi is an AWS Advanced Technology Partner providing you with all the necessities required to get code to the AWS cloud. Pulumi offers a cloud development platform allowing Development and DevOps teams to code, deploy, any cloud app, ranging from serverless functions to container apps, to data services and infrastructure as well.

Pulumi has an infrastructure-as-code SDK that enables you to create, deploy, and manage AWS containers, serverless functions, and infrastructure with the help of programming languages like TypeScript, Python, Go, C#, and Java, and markup languages like YAML. The Pulumi AWS provider packages and CLI further make the process of completing all these tasks within just a few minutes.

The Use of Pulumi and Azure DevOps to deploy infrastructure as code

Infrastructure as code integrates IT operations into the software development team, with scalable and infrastructure configurations that can be further examined. To receive the maximum benefits, IaC tools integrate with other DevOps offerings. This is how Pulumi offers infrastructure as code provisioning, while Azure DevOps, on the other hand, provides version control as well as a build and release tool. They create a pipeline conjointly to define, build, test and deploy infrastructure, and also to share infrastructure configurations.

Pulumi in DevOps allows to make build and release stages for the Pulumi Project. The integration of Pulumi Project within Azure DevOps can extend the pipeline to make changes to the environment. The stages are logical divisions meant to imitate different phases in an app’s lifecycle.

In the stage titled Build, Test & Release, Azure DevOps will establish the project, run tests and then make package and publish an artifact. In the Preview Stage, the engineer or project team can preview the changes made within the infrastructure. Finally, in the Deploy stage, the changes can be approved and can be made live in the environment to provision infrastructure.

Maximizing Infrastructure Management with Pulumi and Terraform Combined

If you’re interested in infrastructure as code (IaC), you’ve likely come across two popular tools: Pulumi and Terraform. Although they have notable differences, they can work in tandem to streamline your IaC.

Don’t be deterred by the initial extra effort required to integrate both tools, as the benefits are worth it. With Pulumi supporting the consumption of Terraform state, you can continue to use Terraform for subsets of your virtual infrastructure. For example, you can keep low-level network definitions in Terraform and use Pulumi for high-level infrastructure design. This combined approach allows for streamlined automation and more efficient infrastructure management.

So, if you want to make the most of your infrastructure management, consider combining the strengths of Pulumi and Terraform.

Wrapping Up

Looking for the right infrastructure as code tool for your business? Both Pulumi and Terraform offer similar functionalities, but there are some key differences that you need to consider. Pulumi is a flexible tool focused on functionality, while Terraform is a mature tool with strong community support and better documentation.

The biggest difference between the two lies in their fit with the DevOps culture. Pulumi uses popular programming languages to bridge the gap between development and operations, while Terraform’s domain-specific language can create silos between departments.
