Developers are losing days every month to infrastructure bottlenecks, compliance hurdles, and inconsistent environments. Platform engineering promised to fix that, yet too many platforms fail before they deliver real impact.
In this comparison of Backstage vs Pulumi IDP, we’ll explore why choosing the right architectural approach matters more than the tool itself.
Infrastructure as Code (IaC) has evolved beyond simple automation into a fundamental shift toward applying software engineering practices to infrastructure management. In 2025, leading organizations aren’t just provisioning infrastructure—they’re treating it as software, complete with testing, version control, code reviews, and continuous integration.
Today, we’re excited to announce a major advancement in Pulumi’s mission to make modern infrastructure as code accessible to every developer: direct support for executing Terraform modules. This new capability addresses one of the most significant challenges our users face when migrating from Terraform to Pulumi—complex projects with extensive module dependencies.
Infrastructure teams struggle with growing YAML configurations and CloudFormation templates that take hours to understand and deploy. Daniel Ward, Microsoft MVP and consultant, shares proven strategies for transitioning teams to programming languages like those supported by Pulumi, including the 10% rule for change management and viral adoption techniques.
SEITENBAU GmbH faced a unique challenge - building a platform for 20+ independent projects, each with different tech stacks, deployment targets, and operational models. Instead of forcing standardization, they built an infrastructure buffet using Pulumi.
Infrastructure as Code (IaC) tools such as Pulumi can provide enormous amounts of leverage, but they must be used correctly to also provide safety. One of our main jobs as infrastructure engineers is to not break things, so leverage without safety is useless. If something is safe, we can change things easily without even thinking about it. If it isn’t, we’ll be up until 2 a.m. fixing what we broke.
Pulumi Cloud empowers engineers to automate, secure, and manage modern infrastructure platforms.
Many companies are building internal developer platforms or modern infrastructure platforms to provide developer self-service while maintaining security and compliance. Companies adopt Pulumi IaC so they can apply software engineering practices to their infrastructure scaling problems and because it is fully open source with a strong community and public roadmap.
At Pulumi, we’re committed to open source—always have been; always will be. Pulumi IaC is entirely open source (Apache 2.0 license), meaning you can adopt and extend it however you like. If you’re new to Pulumi, the open source edition is an excellent way to start modernizing your infrastructure. But as your organization grows and the complexity of your environment increases, you may find yourself devoting significant time to rolling your own enterprise IaC backend features.
Infrastructure as Code (IaC) has revolutionized how cloud resources are managed, allowing for more efficient, scalable, and repeatable deployments. We designed Pulumi IaC to let you program cloud infrastructure using familiar programming languages like TypeScript, JavaScript, Python, Go, .NET, Java, and YAML. This approach not only simplifies the process but also integrates seamlessly with existing development tools and ecosystems (e.g., IDEs, standard unit test frameworks, integration test). You can define infrastructure with code, often in just one line, for serverless, Kubernetes, AI/ML, databases, and more. You can also preview changes before deploying unlike many other IaC solutions. Pulumi IaC is fully open source with a public roadmap. We value working with the community to shape the product through feedback and contributions.
Pulumi is excited to be at AWS re:Invent this week, where we’re showcasing our broad and deep support for AWS across all our products. From automating infrastructure with Pulumi IaC to securing secrets with Pulumi ESC to managing cloud assets with Pulumi Insights, Pulumi makes AWS a competitive advantage. Whether you’re a developer, DevOps pro, or platform engineer, Pulumi delivers the tools you need to build and manage modern cloud applications with ease.
Stop by the Pulumi re:Invent booth #370 this week to chat with experts on the Pulumi team. If you can’t make it to re:Invent, join our workshop, Accelerating Platform Engineering with Pulumi on AWS, on December 11, 2024, to see how Pulumi can enhance your cloud operations on AWS.
Continuing our work to bring the best of modern Python to Infrastructure as Code, we are excited to announce built-in support for uv in Pulumi. uv is an extremely fast Python package manager that can install dependencies up to 100x faster than traditional tools, providing one of the fastest ways to manage your Python dependencies and virtual environments.
