Infrastructure bottlenecks and compliance issues are significant challenges for developers, and while platform engineering aims to address these, many platforms fail to have a real impact due to neglecting infrastructure as a foundational concern. The text compares Backstage, a portal-first platform developed by Spotify focused on service catalogs and documentation, with Pulumi IDP, an infrastructure-first internal developer platform that prioritizes governance, cost control, and security from the outset. Backstage requires a lengthy setup and significant maintenance, making it suitable for organizations with existing robust infrastructure tools, whereas Pulumi IDP offers rapid deployment with minimal ongoing overhead, ideal for infrastructure-intensive environments. The article emphasizes that the success of platform engineering depends on treating infrastructure as a first-class concern, rather than an afterthought, and suggests that Pulumi IDP’s infrastructure-first approach provides a scalable and cost-efficient solution. Additionally, hybrid solutions are feasible, as Pulumi provides a Backstage plugin to combine portal features with infrastructure capabilities.
