CrossGuard, Pulumi’s Policy as Code solution, has reached general availability as part of the 2.0 release, offering enhancements like improved CLI support for managing Policy Packs and the ability for organization administrators to enable or disable them using simple commands. The updated version provides policies with more resource information, such as options, parent, and dependencies, allowing for more comprehensive policy creation, like ensuring DynamoDB tables have scaling policies. Python support has been added, enabling the authoring of Policy Packs using the Python SDK, which can enforce policies across stacks written in any language. Configurable Policy Packs introduce flexibility, allowing organizations to adjust policies for diverse environments, such as restricting EC2 instance types differently in production and non-production stacks. These advancements aim to enhance the user experience for both enterprise and open-source users, with resources like webinars available for further learning.
