ITU‐T's Technical Reports and Specifications 37 The ICT infrastructure is at the core and acts as the nerve centre, orchestrating all the different interactions between the pillars and the infrastructure elements. It is an essential ingredient, since it acts as the \"glue\" that integrates all the other elements of the smart sustainable city in the form of a foundational platform. ICT acts as the \"great equalizer\" (human‐to‐human, human‐to‐machine and machine‐to‐machine) to connect a variety of everyday living services to public infrastructures, such as utilities, mobility and water.
