Platform engineering teams managing infrastructure across Terraform and Pulumi now have a way to unify state management without rewriting a single line of HCL. Starting today, Pulumi Cloud can serve as a Terraform state backend, letting you store and manage Terraform state alongside your Pulumi stacks. Your team continues using the Terraform or OpenTofu CLI for day-to-day operations while gaining the benefits of Pulumi Cloud: AI-powered infrastructure management with Pulumi Neo — our infrastructure agent — encrypted state storage, update history, state locking, role-based access control, audit policies, and unified resource visibility through Insights.

Many organizations have years of infrastructure built and managed with Terraform. Outputs such as VPC IDs, subnet lists, database endpoints, and cluster names are the connective tissue between infrastructure layers. Getting those values into other tools and workflows often means manual copy-paste, wrapper scripts, or brittle glue code.

The terraform-state provider for Pulumi ESC helps bridge that gap. It reads outputs directly from your Terraform state files and makes them available as first-class values in your ESC environments — no scripts, no duplication, no drift. Any output marked as sensitive in your Terraform state is automatically treated as a secret in ESC. If you’ve used pulumi-stacks to read outputs from Pulumi stacks, this is the same idea for Terraform.

Pulumi ESC environments can now validate configuration values against JSON Schema with the new fn::validate built-in function. Invalid configurations are caught immediately when you save, preventing misconfigurations from reaching your deployments.

We’re thrilled to announce that the Pulumi Cloud REST API is now described by an OpenAPI 3.0 specification, and we’re just getting started.

This is a feature that has been a long time coming. We have heard your requests for OpenAPI support loud and clear, and we’re excited to share that not only do we have a published specification for consumption, but our API code is now built from this specification as well. Moving forward, this single source of truth unlocks better tooling, tighter integration, and a more predictable API experience for everyone.

You can fetch the spec directly from the API at runtime or use it for client generation, validation, and documentation, all from one machine-readable contract.

We’re excited to announce ESC Connect — a new capability that lets you integrate any secret source with Pulumi ESC by building simple HTTPS adapter services. If you’ve ever needed to pull secrets from a proprietary system, a legacy tool, or a third-party service that doesn’t have native ESC support, you no longer have to wait for us to build a provider. You can build your own adapter in an afternoon and start using it immediately.

Many teams live with the fear that a production environment might be accidentally opened, exposing credentials or sensitive systems before anyone even notices.

We’re excited to announce a new feature for Pulumi ESC: Open approvals. A governance capability that lets organizations require review and sign-off before an environment is opened (i.e. activated or exposed)

Did you know that 80% of unplanned outages aren’t caused by hardware failures or cyberattacks, but by the very changes we make to improve our systems?

Pulumi ESC already enables safer change management with our innovative versioning capability which allows users to track and roll back environment revisions.

Building on this foundation, we’re excited to announce the release of Approvals in Pulumi ESC—a new feature that enables organizations to bring governance and oversight directly into their environment configuration workflows.

With Approvals, teams can require explicit review and sign-off before applying changes to ESC-managed environments, bringing the same rigor to configuration as they already have with infrastructure-as-code and application development.

Snowflake is the data cloud powerhouse for countless businesses, critical for everything from customer dashboards to billing pipelines. The stakes are immense: this data must be strictly secured and always available. But managing this with static credentials or manual key rotation creates persistent security vulnerabilities and introduces operational instability, risking disruptions during clumsy updates. Pulumi ESC eliminates this dilemma with two purpose-built Snowflake integrations:

1. snowflake-login: Provides dynamic, short-lived OIDC tokens for temporary authentication to Snowflake.
2. snowflake-user: Automates the rotation of RSA keypair secrets for Snowflake users, essential for secure key-pair authentication.

Managing secrets effectively is no longer a “nice-to-have”—it’s a must-have for any organization building and scaling applications in the cloud. Static, long-lived credentials like database passwords, API keys, and IAM user credentials are a major security vulnerability. They’re often overexposed, residing in source code, configuration files, or other easily accessible locations. Manual rotation processes are tedious, error-prone, and infrequent, leaving a wide window of opportunity for potential breaches. Today, we’re thrilled to announce a powerful new capability in Pulumi ESC that directly addresses this challenge: Rotated Secrets.

Managing secrets in modern cloud applications can be challenging, particularly when it comes to rotation policies. While dynamic secrets (like AWS IAM temporary credentials) handle this automatically, many systems still rely on static secrets that require periodic rotation.

Static secrets, like database passwords or API keys, should be rotated regularly to maintain security, and services depending on these secrets need time to transition to new credentials to avoid downtime. This makes rotating credentials error-prone, and often forgotten.

In this post, we’ll explore an approach for automating static secret rotation using Pulumi ESC combined with Pulumi IaC.
