The blog post by Jenny Salem explores the differences between API catalogs and API developer portals, emphasizing the challenges and solutions associated with the rapid expansion of APIs due to cloud-native development and microservices. API catalogs serve as centralized repositories for internal APIs, facilitating discoverability, documentation, governance, and optimization by providing developers with essential information like functionality, usage statistics, and performance feedback. In contrast, API developer portals offer a more comprehensive solution by managing the entire API lifecycle, integrating API data with microservices, and enhancing developer experiences through self-service actions, scorecards, and dashboards. These portals not only improve API quality and compliance but also unify various software components to streamline development workflows, enhance collaboration, and improve visibility across projects. By integrating API management into a broader development framework, organizations can reduce cognitive load, minimize duplication, and accelerate innovation.
