Information infrastructure is a technical structure of an organizational form, an analytical perspective or a semantic network. The concept of information infrastructure (II) was introduced in the early 1990s, first as a political initiative (Gore, 1993 & Bangemann, 1994), later as a more specific concept in IS research.

Software-defined infrastructure (SDI) is the definition of technical infrastructure controlled by computer hardware, that is entirely under the control of software. It operates independent of any hardware-specific dependencies and is programmatically extensible. Drive for innovation boosts demand for software-defined equipment.
Infrastructure as a service is taking the physical hardware and going completely virtual (e.g. all servers, networks, storage, and system management all existing in the cloud). This is the equivalent to infrastructure and hardware in the traditional (non-cloud computing) method running in the cloud.
The report of the GCSC Critical Infrastructure Assessment Working Group has summarized the results of their survey in a comprehensive definition of Critical Internet infrastructure, which includes the following elements: [2] Packet routing and forwarding; Naming and numbering systems; Security and identity protection; Physical transmission media
