An internal developer platform (IDP) enhances developer productivity and velocity by providing self-service infrastructure, service catalogs, and standardized service templates designed to reduce friction and improve the developer experience. A well-structured service catalog acts as a central repository for services, promoting discoverability, reusability, and clear ownership, while service templates offer consistent project scaffolding, built-in quality tools, and documentation to guide developers from the start. Streamlining local development environments and integrating fast, reliable CI/CD pipelines further aids in reducing time to first commit and time to production, ultimately leading to quicker delivery and increased developer satisfaction. By focusing on these aspects, platform engineering initiatives can create significant competitive advantages, enabling teams to move faster and build better products.
