This article discusses the challenges of onboarding new software engineers in large organizations with microservices architecture, where codebases are complex and documentation is often lacking. Internal Developer Platforms (IDPs) like Backstage aim to solve this problem by consolidating information about all components and services in one place, enforcing standards, and streamlining development operations. IDPs provide a standardized set of tools, frameworks, libraries, and development environments across teams and projects, reducing the time developers spend setting up their development environments. They also catalog critical metadata about components, making it easier for developers to collaborate and onboarding new hires faster. Additionally, IDPs incorporate developer productivity tools, enforce security best practices, reduce costs, and improve code quality. However, implementing an IDP comes with challenges such as integration with existing systems, security and compliance, adoption, and ongoing maintenance and support. Despite these challenges, IDPs can increase developer productivity and code quality, making them a worthwhile investment for growing organizations and large enterprises.
