Pulumi's Automation API elevates the infrastructure as code concept by offering a programmatic interface that allows organizations to dynamically create, update, configure, and destroy infrastructure, moving beyond command-line interactions. This API enables the creation of customized Software-as-a-Service (SaaS) applications that can provision unique infrastructure for each customer, addressing specific requirements for security and performance, particularly in regulated industries. By encoding infrastructure knowledge into self-service tools, Automation API facilitates streamlined access for application developers without exposing them to infrastructure complexity. It supports various programming languages, allowing developers to integrate it into custom platforms, developer portals, and CI/CD workflows, as seen in various applications like Mercedes-Benz Research & Development's platform and Pulumi's GitHub Action. The general availability of Automation API was announced at PulumiUP, highlighting its capability to transform infrastructure management and unlock new SaaS opportunities through unique, single-tenant infrastructure offerings.
