Pulumi is an infrastructure-as-code (IaC) tool for defining, provisioning, and managing cloud resources using general-purpose languages such as TypeScript, Python, Go, and C#. It is commonly used by DevOps and platform engineering teams to standardize environments, reduce configuration drift, and apply familiar software engineering practices to infrastructure changes across AWS, Azure, Google Cloud, and Kubernetes.
Pulumi is typically integrated into CI/CD pipelines to preview changes in pull requests, promote updates across accounts or clusters, and package reusable components for consistent patterns. It often complements broader platform engineering efforts focused on guardrails and repeatable delivery.
Infrastructure-as-Code is a way for provisioning infrastructure by describing the state of the infrastructure you want to get as a program that can be interpreted and executed.
Pulumi is an infrastructure-as-code (IaC) tool that provisions and manages cloud and Kubernetes resources using general-purpose programming languages. It is used when teams want reusable, testable infrastructure delivery with software engineering workflows and tooling.
Pulumi is a strong fit for teams building internal platforms, shared infrastructure modules, and multi-environment delivery pipelines. Because it is real code, it also introduces typical software concerns such as dependency management, versioning, and test strategy, and stable deployments usually require provider version pinning and clear state conventions; details are covered in the Pulumi documentation.
Common alternatives include Terraform, AWS CloudFormation, and Azure Bicep, with the best choice depending on preferred authoring model, governance requirements, and target cloud footprint.
Our experience with Pulumi helped us turn infrastructure delivery into an engineering practice—building reusable components, CI/CD workflows, and guardrails that make cloud provisioning repeatable, testable, and safe across teams and environments.
Some of the things we did include:
This delivery experience helped us accumulate significant knowledge across migrations, platform builds, and day-2 operations, and it enables us to implement high-quality Pulumi setups that are maintainable, secure, and aligned with how engineering teams ship software.
