Harness Internal Developer Portal (IDP) serves as an effective bridge between monorepos and microservices, offering features like flexible YAML definition locations, localized documentation, streamlined service onboarding, and path-aware scorecard checks, thus enhancing development workflows. While microservices have gained popularity due to the rise of Cloud Native tools, monorepos still offer significant benefits, such as simplified dependency management and efficient code reviews. The IDP is designed to accommodate both monorepos and microservices, making it versatile for organizations at different stages of their development journey. It allows YAML files to be placed anywhere in the repository for maximum flexibility, ensures documentation is closely aligned with code, facilitates the onboarding of new services without creating new repositories, and provides scorecard checks that are aware of specific paths within a monorepo. This versatility makes the Harness IDP a valuable tool for enterprises and startups looking to optimize their software development processes.
