In the evolving landscape of enterprise technology, the traditional approach of building separate API platforms is no longer sustainable. Instead, integrating API management and capabilities into a comprehensive Internal Developer Platform (IDP) ensures greater agility, efficiency, and coherence in software development. This session explores the pitfalls of isolated API platforms and presents a compelling case for their integration into IDPs. By emphasizing modularity, discovery, and composability, this unified approach can streamline workflows and enhance developer productivity. Drawing from the principles of the Platformless Manifesto, practical strategies, architectural considerations, and real-world examples will illustrate the benefits of this integrated methodology.
