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

The year 2025 marked a significant evolution in platform engineering with the introduction of Pulumi Neo, a purpose-built AI designed to address the challenges faced by platform engineers, who had been struggling to keep pace with the rapid advancements in AI-accelerated development. Neo brings dedicated AI tools to platform teams, understanding cloud environments and infrastructure as code, and operates within Pulumi’s existing platform capabilities, ensuring security and compliance. Innovations throughout the year included AI-assisted development tools integrated with Pulumi's CLI, next-generation policy management for AI-powered governance, and the foundation of Internal Developer Platforms (IDP) for self-service infrastructure. Pulumi also enhanced secrets management to address security risks, introduced comprehensive Identity and Access Management (IAM), and expanded Infrastructure as Code (IaC) capabilities with major cloud provider updates and language support. These developments aimed to transform platform engineering from a reactive process to a proactive, strategic enabler of sustainable velocity in AI-driven environments, setting the stage for further innovations in the future.
