Platform engineering is a specialized discipline that enhances developer productivity by creating automated tools and processes to streamline the software delivery lifecycle (SDLC). It builds upon DevOps principles by emphasizing centralization, consistency, and self-service access, often managed by dedicated platform teams which may collaborate with DevOps, infrastructure, and IT services teams. Platform engineering facilitates the creation of internal developer platforms (IDPs), which serve as centralized toolboxes for developers, simplifying tasks through interfaces like CLIs and APIs. IDPs automate various DevOps tasks, improve build quality and reliability, reduce build times, and enable self-service access to infrastructure, ultimately enhancing developer efficiency and satisfaction. The implementation of an IDP requires careful planning and integration of tools, with popular frameworks like Spotify Backstage aiding in deployment. By addressing common SDLC challenges, platform engineering supports faster and more consistent software delivery, elevating developer productivity and satisfaction while ensuring security and compliance standards are met.
