Ask a generic LLM to “fix my broken deployment,” and you’ll get generic advice. Ask Pulumi Neo the same question, and you’ll get a fix plan grounded in your actual infrastructure state.
The difference isn’t about better prompts or newer models. It’s about what the AI actually knows. Generic LLMs have been trained on the internet. Neo has been trained on your infrastructure.
Welcome to the fourth post in our IDP Best Practices series. Today we’re diving into the world of drift detection and remediation, those critical day 2 operations that keep your infrastructure aligned with its intended configuration long after the initial deployment.
You’ve built a beautiful platform with robust guardrails, comprehensive templates, and well-defined golden paths. Your developers are productive, deployments are smooth, and everything seems perfect. Then reality hits. An on-call engineer makes an emergency change through the AWS console during a 3 AM incident. A team member tweaks a security group rule to debug a connection issue and forgets to revert it. Auto-scaling adjusts capacity based on load patterns. Before you know it, your actual infrastructure has quietly diverged from what your code describes.
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.
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.
