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. This distinction matters more than you’d think. The grounding problem Most AI tools treat infrastructure l...| Pulumi Blog
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-...| Pulumi Blog
Neo just got significantly more capable. We’ve shipped three major updates: Operating Modes for flexible control, full ecosystem tool access, and Claude Sonnet 4.5 for better performance on complex infrastructure tasks. You decide how much control you keep The same action has different risks in different contexts. Building a new dev environment is low risk. Opening a PR that changes shared infrastructure requires more scrutiny. Operating Modes let you adjust autonomy based on context: Revie...| Pulumi Blog
Since launching Pulumi Neo two weeks ago, we’ve seen platform teams discover creative ways to put their newest AI teammate to work. We have also been using Neo internally for a handful of use cases. Neo shifts the conversation from “what could AI do for infrastructure?” to “what can I actually accomplish with Neo today?” The answer is quite a bit. Here are 10 concrete workflows that platform teams can use Neo for right now, each one designed to save hours of manual work while keepin...| Pulumi Blog
Welcome to the third post in our IDP Best Practices series, where we explore how to implement policy as code with Pulumi CrossGuard to create deployment guardrails that make self-service infrastructure both powerful and safe. Platform engineering presents a fundamental tension: we want to enable developer velocity while maintaining security and compliance. Every platform team faces the same question: how do you give teams the freedom to deploy infrastructure quickly without compromising on sa...| Pulumi Blog
AI coding assistants have transformed the speed at which developers can write and deploy code. Pull request velocity has increased significantly. Feature delivery has accelerated beyond what we thought possible just two years ago. This should be a victory for everyone in the software organization. Instead, it’s created significant challenges for infrastructure and platform teams. Every line of code that ships faster creates new platform needs: monitoring, secrets management, deployment pipe...| Pulumi Blog

Building and maintaining reusable infrastructure has always been about more than just writing good code. It’s about making that code discoverable, understandable, and easy to adopt across your organization. Today, we’re excited to announce a new feature that removes significant friction from sharing and consuming infrastructure components: automatic multi-language API documentation in Pulumi Private Registry. The Challenge of Sharing Infrastructure at Scale Platform teams invest significa...| Pulumi Blog

Welcome to the first post in our IDP Best Practices series. In this guide, we’ll walk through the strategic foundations for designing an Internal Developer Platform that empowers developers without sacrificing governance, security, or operational control. At Pulumi, we’ve worked with hundreds of teams facing the same core challenge: How do you give developers the infrastructure access they need, while maintaining the governance and security your organization requires? That tension is at t...| Pulumi Blog
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. Quick comparison: Backstage vs Pulumi IDP Backstage is an open-source developer portal framework from Spotify that focuses on se...| Pulumi Blog

Frustratedly trying to figure out what's actually happeningIn previous articles in this series, we’ve shown how platform engineering turns infrastructure chaos into consistency, gives teams self-service tools, smooths developer workflows, and bakes security into the platform. Each pillar builds on the last. Together, they create an internal developer platform that cuts friction and speeds innovation. Even so, teams still face a big challenge: seeing what’s really happening. Whether things...| Pulumi Blog

2 Months ago, user deacon91, after years of working in the industry has declared DevOps to be a dead end on Reddit’s r/devops. And I’ve been thinking about his thoughts on the industry since then. His point was that DevOps, the breaking down of silos between development and operations, had been tried. We learned the lessons of this approach and need to do something better: Platform Engineering. And platform engineering has certainly emerged as a new hot area. But is it truly an evolutiona...| Pulumi Blog
