ITIL
ITIL (Information Technology Infrastructure Library) is a widely adopted framework of best practices for IT service management (ITSM). It provides a set of detailed practices for aligning IT services with the needs of businesses, focusing on delivering value to customers through efficient service design, transition, and operation. ITIL helps organizations manage IT risks, improve customer relations, and optimize costs.
Developers should learn ITIL to understand how IT services are managed in enterprise environments, especially when working in DevOps, SRE (Site Reliability Engineering), or IT operations roles. It is crucial for improving service delivery, incident management, and change control processes, making it valuable in regulated industries like finance, healthcare, and government where compliance and reliability are priorities.
