A software catalog is proposed as the optimal solution for managing developer portals, offering a comprehensive approach to cataloging infrastructure assets and services within platform engineering. Unlike microservice catalogs, software catalogs aim to reduce developer cognitive load and streamline the software development lifecycle (SDLC) by providing a unified system that covers services, environments, deployed services, and deployments. This approach enhances developer self-service capabilities, minimizes redundant tasks, and improves onboarding processes by establishing a shared language among engineering teams. By offering detailed insights into the lifecycle and dependencies of each service, software catalogs help maintain clarity and control across various DevOps architectures, ultimately improving the developer experience and productivity.
