What is technical operation and maintenance?

Technical operation and maintenance, which refers to Internet operation and maintenance here, usually belongs to the technical department, which is the four major departments of Internet product technical support, R&D, testing and system management. This division will be somewhat different at home and abroad, between large companies and small companies. The general process of an Internet product generation is: product manager (non-technical department) demand analysis, R&D department development, testing department testing, operation and maintenance department deployment and long-term operation and maintenance. Generally speaking, domestic Internet operation and maintenance is responsible for the release and management of software after delivery, and its core goal is to efficiently and reasonably integrate the delivered business software and hardware infrastructure into products that can provide high-quality services in a sustainable way, while minimizing service operation costs and ensuring service operation safety.
