Softwaredefined
Software-defined is an approach to building and managing information technology infrastructure in which the control logic and decision-making are implemented in software rather than in the underlying hardware devices. This enables programmable, automated, and centralized management of resources such as networks, storage, and data centers. The term is often used in contrast to traditional, appliance-centric designs where hardware devices carry both data-path and control logic.
Key idea is the separation of the control plane from the data plane, allowing a centralized controller
Common manifestations include software-defined networking (SDN), which centralizes control of network forwarding; software-defined storage (SDS), which
Benefits include increased agility, improved utilization, and easier policy enforcement. Challenges include system complexity, potential security
Software-defined approaches continue to evolve with emphasis on automation, policy-driven management, and interoperability across hardware and
