Change your components, keep your infrastructure (opens on the source site)
Pulumi ·
Components let you turn a group of resources into a reusable building block. You can define a network, a database, or an application service once and share it across projects and teams. People using the component work with its inputs and outputs without needing to understand every resource inside it. Suppose you built your network with the legacy AWSX VPC component. It manages the VPC, subnets, route tables, and gateways behind a few lines of code. Now you want to upgrade to the modern AWSX component. Later, your needs change again: you want more control over the resources than the component…
Self-driving infrastructure with Pulumi and Jev (opens on the source site)
Pulumi ·
It’s been a weirdly great time to be building software. We’ve never had so many tools that help us get things done: endless cloud providers, regions, deployment frameworks, and now AI agents that can actually build and manage infrastructure for us. That’s part of what made this past week feel so big. TypeSafe AI opened early access to Jev, their SystemOne model, and we here at Pulumi were bitten by the excitement bug and got straight to work building. Almost immediately we were able to whip up some test agentic workflows that were making real, live decisions about infrastructure. If you’re…
How Criteo Measures Bare-Metal Infrastructure Carbon (opens on the source site)
Criteo ·
Authors: Aida Cissé, Omar Ait Mous, Vera IlinaFor many years now, we have been computing the global carbon footprint of the Criteo Bare-Metal Infrastructure thanks to the plethora of data we have at the data-center-level — yearly electricity consumption, PUE, the carbon impact of manufacturing the servers, …This was enough for some time as it allowed us to monitor our impact and work on achieving our SBTi commitments. But as awareness grows, people and teams start asking questions to understand the impact of their applications and their share within the global picture.Due to the lack of more…

Implementing GitOps from Infrastructure to DB Operators to Unify Ops for Kubernetes Databases (opens on the source site)
Most platform teams already use GitOps for their Kubernetes apps. The config lives in Git, Argo CD applies it, and deployments are predictable. But look one layer down and things get messy. Infrastructure setup is often still done by hand, running Terraform locally or through scattered scripts. Database operations, especially for databases running through Kubernetes […] The post Implementing GitOps from Infrastructure to DB Operators to Unify Ops for Kubernetes Databases appeared first on Severalnines.

Becoming an AI Team (opens on the source site)
John Grass | Sr. Manager, EngineeringA Fundamental TransformationAn AI team is fundamentally more than just a group whose members incorporate AI tools into their existing workflows. The journey to becoming an AI team necessitates a fundamental and comprehensive paradigm shift in how the team defines ownership, engages in strategic planning, and, most critically, executes on its core goals and objectives. This transformation is not merely an addition of new technology; it is a restructuring of the team’s operating model, philosophy, and individual roles.Becoming an AI team requires a holistic…
Neo Security: Securing Infrastructure in the Agentic Era (opens on the source site)
Pulumi ·
Recently, AI systems have started turning up exploitable flaws in code that survived decades of human review. The frontier labs have released useful tools to help uncover many of these flaws through agent-led static code analysis. This is a huge leap ahead, but cloud infrastructure has many exploitable flaws that code analysis alone cannot find. These flaws are often as severe as the ones in code, or worse, and they await discovery by malicious agents on offense. We realized recently we can uniquely help here. At Pulumi, we have complete visibility into your entire cloud estate:…

Pulumi Context API: query your infrastructure as a graph (opens on the source site)
Pulumi ·
Every platform team fields the same questions: What is running? What breaks if we change this? What can we safely delete? The answers exist, but they’re scattered across state files, cloud consoles, and the memories of whoever set things up. Today we’re launching the Pulumi Context API, a read-only API that connects Pulumi-managed and discovered resources, stacks, and their relationships into a graph. It’s designed agent-first: Pulumi Neo, our infrastructure agent, uses it out of the box, and other agents can fetch the current graph vocabulary and query guidance on demand. It’s available in…

Best Kubernetes Infrastructure as Code Tools in 2026 (opens on the source site)
Pulumi ·
There is no single best Kubernetes infrastructure as code tool, because “Kubernetes IaC” actually spans three different jobs. For provisioning the cluster and its cloud dependencies, Pulumi and Terraform (or OpenTofu) are the strongest general-purpose options. For templating and packaging workloads, Helm and Kustomize dominate. For continuous reconciliation once things are running, Argo CD and Flux lead the GitOps category. The right stack usually combines one tool from each layer, not a single tool that claims to do all three. What counts as infrastructure as code for Kubernetes? Kubernetes…
Flexible Authentication: Reimagining authentication for millions of users at Airbnb (opens on the source site)
Airbnb ·
Rebuilding login and signup surfaced product insights, not just technical challenges. Here’s how we designed Flexible Authentication at the intersection of product intuition and technical architecture.By: Jose Santos, Mike BarryFor Airbnb, logins at irregular intervals are normal. A guest books a trip in January and may not open the app again until summer. A host checks back only when a reservation comes in, and may be busy with other activities when it does. For a two-sided marketplace where a failed login means a lost booking, and lost revenue for both the guest and the host, long gaps…
Never Miss What Your Infrastructure Is Telling You (opens on the source site)
Pulumi ·
Plenty happens in a Pulumi organization while you’re looking somewhere else. Neo finishes a task you kicked off just before taking lunch. A teammate submits an ESC change request that needs your approval before it can land. Until now, catching any of that meant either keeping the right tab open or hoping the right email reached you. Today we’re introducing the Notification Center: a single inbox in the Pulumi Cloud console for the things that actually need you. It lives behind the bell in the sidebar, with a dot when something’s waiting. Notifications arrive in real time — no refresh — and…
7 Tools for Multi-Agent Infrastructure (opens on the source site)
A single agentic workflow calling a single API is an easily tractable engineering problem — the solutions exist, and it’s ultimately just a problem of visibility and integration. A fleet of specialized agents delegating tasks to each other, sharing state, and discovering tools at runtime is decidedly more difficult — almost an order of magnitude ...

Discovered Stacks: One Place for All Your Infrastructure (opens on the source site)
Pulumi ·
Today we’re launching Discovered Stacks: Pulumi Cloud now models your AWS CloudFormation stacks and Azure Resource Manager deployments as stacks, right alongside your Pulumi IaC stacks. And when you’re ready to bring them under Pulumi management, migration is built in, with every resource tracked until the code provably matches the cloud. Why: your infrastructure doesn’t live in one tool Almost nobody’s cloud estate is a single technology. There’s the CloudFormation that came with the AWS account, the ARM templates from the Azure team, the Terraform from an acquisition, and the Pulumi you’re…
