Platform engineering is a rapidly growing trend in software development that aims to solve complex problems faced by organizations in the cloud-native era. It involves designing and building toolchains and workflows to enable self-service capabilities for software engineering organizations. Platform engineers provide an integrated product, referred to as an Internal Developer Platform (IDP), which covers operational necessities of the entire lifecycle of an application. A platform as a product approach is at the core of platform engineering, where successful IDPs are treated like any other product and built to deliver value to the organization. Key characteristics of a compelling IDP include being self-service for most use cases, composable, quick and cheap to start using, secure and compliant by default, and having a rich internal user community. Platform teams should define their own mission statement, dedicate product managers, conduct user research, create roadmaps aligned with key priorities, invest in tight feedback loops, and consider building or buying an IDP. An enterprise-grade IDP should provide automatic documentation of configuration changes, full version history, integration with UIs and service catalogs, and a Platform Orchestrator that enables Dynamic Configuration Management.
