Neo: Zero-downtime migration from CDK, Terraform & Azure ARM

The barrier to migrating to Pulumi has always been the infrastructure you already have. Your existing resources can’t be disrupted, and manually importing them into a new tool is risky and time-consuming. Today, we’re excited to share how Neo removes this barrier entirely with automated, zero-downtime migration to Pulumi from AWS CDK, AWS CloudFormation, Terraform, CDKTF, and Azure ARM templates.

Introducing the new and improved ESC Editor

Introducing the new and improved ESC Editor

Pulumi ESC is Pulumi Cloud’s centralized solution for managing secrets and configuration across every vault and cloud provider you use. It helps teams secure their configuration while adopting modern best practices like short-lived credentials with OIDC and automated secret rotation.

Whether you’re configuring Pulumi programs, powering applications and services, or managing credentials for tools like the AWS CLI, ESC provides a single, consistent way to do it safely and at scale.

Behind the scenes, ESC integrates with multiple cloud providers and secret managers, supports composable environments, and offers rich built-in functions, from simple value transformations to encoding files as Base64.

With this level of power, usability matters more than ever. That’s why today we’re introducing the new and improved Pulumi ESC Web Editor, designed to make managing secrets and configuration easier, faster, and more intuitive.

How Ralph Wiggum Built a Serverless SaaS with Pulumi

I was about to do something that felt either genius or completely reckless: hand over my AWS credentials to an AI and step away from my computer. The technique is called “Ralph Wiggum,” named after the Simpsons character who eats glue and says “I’m in danger” while everything burns around him. And honestly, that felt about right for what I was attempting.

Kubernetes ConfigMap Revisions with Pulumi

ConfigMaps in Kubernetes don’t have built-in revision support, which can create challenges when deploying applications with canary strategies.

When using Argo Rollouts with AWS Spot instances, ConfigMap deletions during canary deployments can cause older pods to fail when they try to reload configuration. We solved this by implementing a custom ConfigMap revision system using Pulumi’s ConfigMapPatch and Kubernetes owner references.

Speeding up Pulumi Operations by up to 20x

Today we’re introducing an improvement that can speed up operations by up to 20x. At every operation, and at every step within an operation, pulumi saves a snapshot of your cloud infrastructure. This gives pulumi a current view of state even if something fails mid-operation, but it comes with a performance penalty for large stacks. Here’s how we fixed it.

Introducing the Stash Resource in Pulumi IaC

We’re excited to announce the Stash resource, a new built-in Pulumi resource that lets you save arbitrary values directly to your stack’s state. Whether you need to capture a computed result, record who first deployed your infrastructure, or persist configuration that should remain stable across updates, Stash provides a simpler and more ergonomic solution.

How to Move to the Gateway API: post ingress-nginx Retirement

The upcoming retirement of ingress-nginx in early 2026 gives infrastructure teams both a deadline and an opportunity to rethink traffic management. Configuring the Ingress API often meant relying on controller-specific annotations that varied between implementations. The Gateway API offers a cleaner, standardized alternative. This post investigates the practical reality of this migration and explores why kgateway emerges as a robust solution for the future.

Pulumi 2025: Neo, Next-Gen Policies, and Platform Engineering at Scale

The era of AI-accelerated development has arrived, creating both unprecedented opportunity and unprecedented challenge. Developers ship code faster than ever, but platform teams struggle to keep pace. The velocity gap threatens to become a bottleneck.

As 2025 comes to a close, let’s look back at how we addressed this challenge.

This year, we took a giant leap forward to close that gap with several major innovations, including purpose-built AI for platform engineers, next-generation policy management that transforms governance into an accelerator, and the foundation for building Internal Developer Platforms that enable self-service without sacrificing control.
