If you're looking for a service that can generate infrastructure code with AI and natural language prompts, and supports modular environments and internal developer portals, Pulumi is a great option. Pulumi is an open-source infrastructure as code (IaC) SDK that lets developers write, deploy and manage infrastructure across multiple clouds in languages they already know. It's got a code engine that uses AI to generate code, supports modular environments, and offers internal developer portals, so it's a good fit for teams that want to boost productivity, scalability and collaboration.
Another contender is GitHub Copilot. Although geared for software development, GitHub Copilot can turn natural language prompts into code suggestions, which can be useful for generating infrastructure code. It offers context-aware help as you write code, works in a variety of IDEs and terminals, and integrates with other GitHub features to help developers code more efficiently and write better software.
