Note
The everyday sense is the one that fills news pages: roads, bridges, dams, water mains, sewers, power grids. It often stands before another noun, as in an infrastructure law or water infrastructure. Where the systems-theory sense is abstract, this one is concrete. Last Week Tonight with John Oliver (2015) joked that it is anything an action movie can destroy, which is a fair test of the meaning.
- 2The underlying base or foundation that supports a building, organization, or system.
The organization's entire infrastructure rested on a handful of overworked volunteers.
Without a sound technical infrastructure, the platform could not scale to millions of users.
Similarfoundation, framework, backbone, base, structure

Note
Systems theory uses the word for the layer everything else stands on. It was borrowed from French, where infra-, meaning "below," is joined to structure. Its natural opposite is superstructure, what rests on top. Understructure and underpinnings draw the same picture of support from beneath. It can be countable (an organization's infrastructure) or a mass noun for underlying systems in general.
